Nick! This episode is gold. Thanks for your hard work and knowledge. You're THE guy to do this kind of video. Please let us look over your shoulder in the future as you consider the weather on future trips.
Must admit that a lot of the info (especially the interview portion) was over my head as not educated enough on the topic to follow! I would love you to walk us through some passage planning scenarios using predictwind and your thoughts process as you determine whether or not to go/when to go.
I'm interested in really long passage planning, like West Coast N America to S. Pacific. Is it even possible to plan that long range? Do you just sail and tweak your routing as you get updates?
@@benlindner5285 Quote you ; " Is it even possible to plan that long range?" If possible, I would harbor hopping, and make passage planning decisions as you go. Other than that there are the recurring patterns. Summer weather is better than winter weather. There is a cyclone/typhoon/hurricane (⇽ those words have the same meaning) season, and the monsoon season as well.
I’ll try to do more of that. There is some passage planning in some videos from a year and a half ago....check the channel, I think the thumbnail on one of them is “Is you go How Fast?”
Yes Ben, on long passages, you wait for the proper time of year when average conditions are most favorable, then you head off with a good window and tweak along the way.
YES YES YES, Please give the break down as if explaining to a (idiot) child. lol... Very Tough digesting this when not familiar at all. Thanks my friend,,, LOVE the content!
Thank you for a very informative video! All complex systems are interesting and it's easy to forget the knowledge required to understand them, whether it's weather, a stock exchange, power grid distribution or fluids in a jet engine. Thanks for sharing!
This is the video I've been waiting for, knowing that you're a meteorologist. Fantastic job, great information, well presented! Thanks!! [Edit: forgot to mention: Loved the intro talking point about the dynamics of the two largest fluids on earth. Nice perspective!]
Nick, wanted to let you know that I totally geeked out on this. I’ve been using PredictWind for a while now is my go to and it was great affirmation hearing from both you and the founder of predict wind. Weather is never a constant in the power of mother nature is always awesome, so thank you so much for doing this video
I can recommend a couple of older books that are useful to cruisers that we have found helpful: "Mariner's Weather Handbook" and "Surviving the Storm", both from 1999 by the Dashews (Steve and Linda). The latter should be in every cruiser's library. Although we have some nicer tools now than weatherfax (still important), his advice and case examples are still good, imho.
This is a much needed amplification of weather tools available to sailors today. Personally, I would put that information ahead of GPS based navigation when off shore! Well done!
Great video. We have used Predict Wind standard for cruising from Pensacola to the Keys/Bahamas for the last three years. The passage planning is great for picking the window (from four sequential days). After picking the day, you have the four models to review for the passage plan. (The CAPE model is also helpful to forecast the potential convective activity.) Predict Wind is very accurate and it's fun to compare the models along the passage.
Thank you for this “deep dive” into what goes into forecasting. Despite the complexity of dealing with so many variables you make it easier for the layperson to understand just what goes into accurate modeling and forecasts. Thank you again
Great tips. I’ve always had a fascination with the weather and the sea, and even took a couple of meteorology and oceanography courses in university when I was attempting to steer myself for a commission with the Air Force 10 years ago. This really puts in perspective just how little I scratched the surface, but I may just get some more courses under my belt for better understanding the nuances of forecasting from boundary conditions. Thanks for the resource recommendations!
I used to use Herb Hilgenberg, via SSB for Atlantic/Caribbean routing back in the early 90's. He was based in Burlington Ontario, and held a check in Net every day for years routing sailors. We always sent him a nice 'stipend' every yr. Thanks for this vid. It's excellent to have an experienced users perspective.
i watched and listened twice and now realize that i need a weather terminology dictionnary, so if this is the intro to weather mapping, weather 101 will be most interesting (i used will be) , because im hopeful. Just noticed that your eye has completly healed, im very happy about that although i kinda miss the pirate patch, and lastly i miss the yatch rock, great work, stay safe.
Saw the beginning and thought that looks like the PNW coastal range and sure enough... Fun discussion on the weather app and models at the end. Very valuable to get into the geek level detail questions with the designer. Having sailed in the sound and Hood's canal the thermals are always a thing. Sailing near land mass especially with mountains and the cool water below you learn quickly to pay attention. You can run up/down a coastline avoiding general offshore wind/current trends if there is a local variation that is favorable. This is also true on the east coast where I am now. I get interior wind patterns plus thermals until I get closer to the ocean and then there is confused wind and then the offshore trend dominates.
As others have mentioned, would love to see a "weather 101" episode or even mini-series. From a theoretical introduction, to global systems, to the effects of local terrain. I wish I could look at the jet-stream-level map and have some idea of what local effect that will have.
Well that was fascinating and underscored how little I know about the weather or the wind models (Predict Wind) I use. Learning more will become another of my winter projects. Thanks for doing this.
I watch you guys, and I watch Delos. I really appreciate that you don't try to imitate Delos. I watched two episodes on another channel, and they even danced around to the Delos theme song. I love what Delos does, but I envision myself sailing more like you guys. Love these in-depth discussions of sailing topics. Fair winds and following seas!
Wow, a lot to digest. And the comments echoed many of my own thoughts and questions. Now I realize I’ll need to budget time (learning curve) and money for one of the most important ingredients I’m seeking when sailing offshore... Good Weather!
Thanks for this, Nick. I hadn't realized that there is a free level of Windy. I just downloaded it, despite not having a boat yet, to flesh out the information for the typhoon season here in Tokyo. It's fascinating to see the winds in Windy and compare it to the track and forecast discussion on CIMSS Tropical Cyclones.
Weather novices have been educated by masters in this video, for which I sincerely appreciate and thank you! Perhaps this is an intro to a few weather classes by our favorite offshore team. Would you consider minimizing our weather naivete with a walk through of a route planning through interesting patterns? This long awaited video is awesome! Thank you
As a pilot, you use all available weather tools, and in my opinion you can't ever learn enough on the variables of changing weather, wind and clear shear. Thanks for sharing this info as I live just a stones throw from the ice near Lockwood Folly inlet, NC coast. I will explore the mentioned programs.
Do a bit of flying when I can as well. Luxury we have on the boat weather-wise is a little more time to consider things, usually less risk of icing, and with Clarity....unlimited fuel.... :) Fly well my friend.
Thanks Nick, great review of Predict Wind, I have downloaded it and use it. As a retired U.S. Army Intelligence Officer we briefed commanders on weather effects on battlefield operating systems, terrain, flight and and of course troops on the ground. As well I have a minor in geography from Southern Illinois University which had a weather component to it. I am a bit of a weather nerd so, I love what your are talking about and understand just how important weather data is before you go on voyage across the ocean. I am coming to you from Turks and Caicos, Seven Stars Resort and Spa. Doing some Scuba tomorrow and am looking forward to getting under the water. But had to look at the weather data to get back out on the water... Good look to getting back to Clarity when you do. Be safe and we look forward to your next videos.
Hey Ron, I (Nick) was a geography undergrad after my meteorology program was cut by Measure 5 legislation. Love geomorphology myself. Enjoy T&C! Say hi to the fishes for us.
excellent my wife and I are going to go board our first sailboat next week and sail it down to florida from new york, very nervous your video helps alot with the detailed information you provided. Thank you very much
Another great video guys. As always, I learn a lot from watching your channel, so thank you for taking the time to produce these super informative videos.
Hello Nick If there is a library of must keep must watch videos, this one will be number one. That was one of the most interesting videos I have ever watched. If I was a fan of meteorology now I am addicted. Thank you , amazing knowledge. Cheers from NYC
Thanks so much for this well produced and structured video. As a long time pilot I have slightly more understanding than the average Joe (only slightly) but of course my predictive capacity is improved by the average very short window needed for a safe flight and restricted to the areas well above the surface. People rarely appreciate the incredible complexity of these models and the dependency on limited data collection ability especially offshore! I have only sailed offshore a few times and that was a number of years ago when these models and apps were not available. It was hold your wet finger up and look at the wind vane and barometer. Scary stuff sometimes. Thanks again for the video and the info on the available predictive software that can now significantly improve both my knowledge and my peace of mind. Stay Safe.
@@TheOKellys Absolutely! It is wonderful the age we live in with the rapid advancements. The old Arthur C. Clarke adage holds true, "Any sufficiently advanced technology will be interpreted as magic to the natives". Welcome native!
Another fantastic video, I’m so happy that you Able to get the interview and you did an awesome job. I’d like to see you do more on this type of video in again thanks so much be safe and take care
I'm looking for my first sail boat now and am studying all the info I can find. Wanted to thank you for all of this and have been following you for a bit now. Maybe someday ill see you in a warm sunny harbor in the Caribbean.
Your obvious passion for sure. Bit above us mere sailors - would be nice to see a series of short videos on a specific decision making process given a set of conditions. Because of this ... we decided to do xyz. Thanks for the great content.
Good idea. When we get underway again on Clarity in a couple weeks, I am going to do a bit more of that...or will try. I do get the feeling that this is boring stuff for a lot of people...but it shouldn't be...absolutely critical to good trips.
@@TheOKellys Don't believe sailors find it boring at all, but short takes on how you process the info for a voyage is practical and we can all learn from it.
As a fellow met, I found this video informative and entertaining. People would be surprised to find how many mets are unable to communicate wx info to the non-met people.
Weather Professor Nick, great video, excellent guest, alumnus and sailor, another weather headjust like you, thanks this information and insight makes us all better sailors! Love it man! Thanks for sharing
Well, that was just awesome. Thanks for the info. I find software generally easier to use once I understand what the developer's intentions are. So getting it straight from the horse's mouth makes predict wind's features and foibles far clearer. To me the key was that it's really about showing the range of possibilities to be prepared for.
exactly. anyone who says..."hey the model was wrong"....just doesn't understand how models work or how to forecast. For the foreseeable future, a human being is required to make a good forecast. That will change eventually, but for now....a (skilled) person needs to know the limitations of each model and the range of possibilities. This video wasn't really about forecast, but maybe that's a topic for another video.
Nick, great video about life importance matter for sailing. Please keep including the short one minute introduction to weather forecast and rout with clouds type identification on each sea passage. It makes a useful practice.
I can recommend a couple of older books that are useful to cruisers that we have found helpful: "Mariner's Weather Handbook" and "Surviving the Storm", both from 1999 by the Dashews (Steve and Linda). The latter should be in every cruiser's library. Although we have some nicer tools now than weatherfax (still important), his advice and case examples are still good, imho.
Best book I've ever found on weather - Modern Marine Weather by David Burch, recommended by those who have gone before me. It blows me away how much more information he provides and in such a way that if I read it some of it a few times, I comprehend. What a great video you did. Really enjoyed the interview. Q: what does it mean when a model "blows up" or "runs away"? I really appreciate you taking the time to do this. I have started the PW / Iridium Go purchase process no less than 3 times in the last few months and then pulled back. I'll check out your affiliate link.
There are a lot of positive feedback processes in the real atmosphere...”nonlinearities” we call them. Too many and too detailed to get into here. But bottom line, in the real atmosphere, little things can have tremendous effects. So the geniuses who build these models try to capture these nonlinear processes, but they can be “too sensitive” in some circumstances and the model solutions get out of control with feedback loops sometimes. That’s what we mean by blowing up. Now this happens with all models all the time, and so there are “smoothing” algorithms applied at some grid scales and time scales in an effort to keep things reigned in....but that can go too far as well.... So the best models for any particular kind of initial conditions are best at “attenuating” these nonlinear processes realistically. It is a very difficult task for any model.
Very informative. Would like to see you do a follow-up video focusing on voyage planning using the apps. Really like how professionally you are invested in this topic. Really showed what to expect from these apps. I want more! Saved in my favorites.
This is very interesting! Since moving to the South where I am now in Tornado Alley and tropical storms, I have really taken an interest in the weather and what it is doing, so I know what to expect. I consider this to be my training! LMBO
Excellent video - thank you! Unless I missed it, I don't think you mention the free portion of PredictWind, which is all we use. The PWE and PWG models are available down to 8km resolution for free on both phone and web/laptop.
I'm fascinated with atmospheric science and would like to learn more about forecasting, without going back to graduate school. This video was very helpful. Do you have additional advice for developing a theoretical underpinning of forecasting?
Great episode. Very informative. I wish all of my hobbies were not weather dependent (sailing, flying..etc.). I'm curious if you've seen forecasts that were way off....so off that it was dangerous?
Yes, sometimes. There have been several documented cases of "bomb cyclone" formation which all of the models miss. We were actually caught in one of those staying in at Lucaya many years before the sailing adventures. Mostly though, I see models overdoing it in some frontal situations and "overreacting."
Man, it is completely different. Everything in aviation is soooo much more structured, from nav to weather to planning.... If people had to operate boats like you do planes, no one would sail.
I agree on the structure comments by Nick! When I was just a VFR (visual flight rules) pilot it was more fun. When I became IFR and type rated in a jet I was safer but flying became less about flying and more about procedures and weather. As far as Foreflight, there would be (as Nick stated) more data to add to your data pile. But for what (I think) you would get out of it and for the effort likely a minimal benefit. So for me 2 thoughts here, if conditions are dicey enough to substantiate digging into foreflight one probably should make the “no go” decision and wait for a better window. On the other hand, if I was stuck in a really bad situation I would use any data available. Lastly, one thing I find very useful in aviation is Pireps. With weather forecast already being analyzed I find actual accounts of reported conditions along my route very helpful. In aviation We have such a shorter time of exposure. I’m not yet experienced or have a solid education in weather for sailing. I see that many Pireps my be used in the models supplied now. Could be a benefit to have current reports plotted on the map for consideration? Another thing aviation has available is routes used by other pilots recently. FLTPLAN make suggestions on routes base upon other flights made recently. Possibly this is a consideration already given inside PredictWind’s routing? Idk. Nick finds these things out! Great video and thank you for sharing your knowledge with us. I’m not ready but I can promise I’ll be watching all your video’s on weather and gaining more knowledge until I’m more confident!!
ShipReps are a thing already, and I talked to a gent from NHC about a program to incorporate more of those from small vessels. No timeline, but that really will make a difference. Suggested routes....now there could be issues with that as bottom contours change a lot over time, especially in shallow areas. Not so much an issue in the skies....
That will be very useful to everyone but possibly more value to someone like me learning. If I’m lucky enough to experience doing a crossing it would reassuring to see actual reports substantiate the weather I’m pulling down. Actual observations are valuable and mostly very accurate but caution still needs to be taken. Example: I was descending into Dallas, was given by the tower while on final, the aircraft just front of me were reporting taking on ice from 2500’ to 2000’ melting and shedding off after descending through 2000’ and before landing. We took ice starting at 2000’ and all the way to the ground. Landed with ice. Lesson: information is good but still not guaranteed. This was maybe 5-10 minutes difference in time.
I still think it would be great to collaborate on trying to find a format to do a primer on basic weather. I’m reminded of a time when my son (I think he was five at the time) asked me, “mom, what makes wind?” My inner weather nerd came out and answered, “unequal heating of the Earth’s surface.” My son did not ask me weather questions again for a couple of years. Is that a mom win or a mom fail? Great vid this week. I always enjoy the weather ones!
There is an interesting book called *Modern Marine Weather: From Time-honored Traditional Knowledge to the Latest Technology* ISBN-10 : 0914025589 ISBN-13 : 978-0914025580 Editorial : Starpath Publications (30 marzo 2018) The book on amazon.es www.amazon.es/Modern-Marine-Weather-Time-honored-Traditional/dp/0914025589/ref=sr_1_1?keywords=Modern+Marine+Weather
Hi guys! Thanks for all your usefull content in your videos. I see the only main difference between the standard and professional package is the Ocean/Tidal Currents feature. In your opinion, is it worth paying double for that one feature? (a circumnavigation is in future plans)
Hey there! Other difference is the 1km resolution model data and more extensive gribs from ECMWF, including wave model. Both the ocean and 1km data is going to be very hard to access offshore due to file sizes. However, if you are going to be operating around strong currents like off E coast of USA, SE coast of Africa, N of Australia, that can be very useful with passage planning. The high res model data is also most useful around land masses where cell signal is going to be more realistic. So yes, you are paying a lot more, but there is also a lot more potentially useful data. If this is all new, go for Standard and upgrade. If you are into serious offshore prep already, I do think having all the Pro data is helpful.
GREAT video! Based on your experience at what duration of passage does adding Iridium or other satellite service become very important for updating weather while underway? A forecast obtained at departure might be great for the first two days, but then accuracy would progressively decline.
We feel pretty naked without satellite connection for more than a couple days. But it depends on the time or year and location. In the trade winds, I’d probably feel ok with a three or four day passage without satellite, but in the substropics or mid latitudes, more than 72 hours without weather would bother me a little.
In a world of vlogs in which everyone seems to think the world wants to watch a sexy young woman in a bikini pull up an anchor (and they may be right) this is refreshingly educational, relevant and helpful. Very well done.
I have predictwind and sailflow, both paid versions. I find Sailflow more accurate when using local/coastal short range forecasts for local races, mostly on Chesapeake Bay. Sailflow mid Atlantic 2km model is usually very good for short range. For route planning, I like SailgribWR, paid version. It's sort of an Android version of Expedition routing and navigation software on Windows, albeit much slimmed down.
Really? I will look into the Sailflow. The WRF may have made some strides over the years. It was a hot mesoscale model for a while in the 90s when developed at NCAR. If Sailflow is running nested grids based on it, it must be quite computer intensive for them. Are they running it just in regional grids?
@@TheOKellys can't comment on what sailflow is doing with the model, just my experience in using it. It's usually really good at local forecast, typically within a few hours of the race, for a race lasting a few hours or a day. This past season doing Wed evening races off of Annapolis, when we can get late afternoon showers or local wind anomolies it has been really good. Predictwind 1km forecast is great for overall trends but seems to smooth local disturbances out. Overall though, I check both PW and SF all the time and keep my eyes open on the race course. Neither seems perfect, gotta make judgements with both as inputs.
My network (ham) has some old salts trying to deliver the best weather we can find. We read it as part of our "Chubasco" network, most of it is geared for the Baja area. But, we will do "fills" for someone in a different area. We are on at 7:30 am 14:30z right now , to change an hour,, soon. This is for those who cannot get weather from "cell" signals. We are on 7.192 mhz every morning. We have sailors in Washington, Oregon , and California. If your a ham we are set up to receive even the very weakest Side-band signals with our "relay" format. I think the future will be in the use of "weak signal" modes. I would be able to transmit to and receive boats From Hawaii east to the shores of California, and they would be able to receive my digital hf signals also. The mode with the most promise is JS8CALL or JS8 for short. The gear is really inexpensive, an HF radio, and a sound card. Many radios have them inside when you buy them, or you can add a Signalink. You could transmit an entire weather forecast fairly quickly and ALL boats could receive it regardless of what frequency in the JS8 40m band they were listening to, and regardless of what speed they were set to. I would receive the slower speeds best, but my signal is so strong I could transmit the weather to their screens at 50 words per minute ! I'm extra class amateur operator N6GRG
One of the big wind events we have to deal with is th PGE safety shutdown forecast. We are going into one I believe tomorrow.. I actually think they missed one, I live right next to the Zogg fire. The wind was coming from the north, a few degrees to the east and I would have been in it.
Then I bet you remember Don of Summer Passage. We relied on him often. Such a kind service he, and now you provide for Mexico sailors. I should have probably mentioned it, but we do carry a receiver on Clarity. We will listen in on the nets from time to time.
@@TheOKellys Awesome, love that we are being listened to. Please consider the JS8CALL as I think it is the future for marine as signals are weak for boats with marginal antennas. Thanks.
I am big fan of predict-wind, I use the high precision model to plan sailing on my local harbor. Weather 4D recently drop Android support as it is not a 64 bit app and google play store has dropped 32bit app. The IOS app is still supported and under active development
Very helpful. A bit of a geeky :) conversation with the guy from PredictWind but very interesting nonetheless. I think an aspect that the models/discussion seem to miss or omit is the effect of bottom topography, ocean current on sea state. I could be wrong on this but I never hear it discussed as a factor in the ocean sailing models. I would love to see a practical discussion of that because sea state more that wind is what makes a passage difficult for most sailors/crews/families. A passage can be great and then a few hours of horrible seas can completely frighten a crew. In many ways the likelihood of bad/short/steep waves is something that can be anticipated by understanding bottom topography. If its anticipated it become less of a "out of nowhere" event. Anyway, thanks for an informative video.
Coastal contour has a much larger effect than bottom topography except with really big waves or really shallow water, at least on the "open" ocean. That being said, I am not familiar enough with the mechanics of ocean models to tell you at what scales these factors become important. What I can speak to is the effect of currents on wave heights. Wind opposing current can make for really big seas if both are really significant and the modeling of these things is still quite course. I expect significant improvements in the coming years as supercomputers become faster and cheaper.
@@TheOKellys What I'm talking about is longer passages over routes where sudden changes in ocean depth would play a factor in sea state. Take for example a passage from Puerto Rico to the Bahamas. The Navidad bank or the the Silver Bank are places that I would avoid in rough weather. I never hear people talk about these considerations in voyage planning. Sea mounts and rapid changes in ocean depth occur all over the place. "Beware the 100 fathom line". :)
@@TheOKellys To follow up - the lovely thing about cruising is going to new places. The scary thing about cruising is going to new places. In familiar places we know where waves or conditions are tough. How do we figure that out in new places. Learning to "read the bottom" is, I think, an important skill in anticipating or avoiding tough conditions. Just my 2 cents worth. Take care. :)
Oh, for sure those are tricky spots. Seems a boat (not necessarily a cruising boat) is lost on Silver Bank every other year. We’ve had crazy waves over seamounts a couple of times. Once was Thetis Bank off Cape Lazaro in the Pacific. Those were unusually large seas to begin with, and the survey of Thetis is incomplete. I know a fair bit about gravity waves, and the bottom doesn’t effect waves until dept is about twice the wave height. However, what does happen around seamounts and other big shoals are strong and changing currents, which like I said earlier, can have a tremendous effect on waves. Yes, the new places and new faces are a big draw for us as well.
Excellent episode! A little off topic but, I didn't know your boat was running for a political office in my area. The political sign on the side of the road said "Vote for Clarity".
Love this content. It’s great info that seems to be said but not explained on other channels. I wonder what you think of the app “MyRadar” they have added lots of features over the last year. Also - do these models take into account solar radiation or surface heating and water temps to forecast? Not i don’t have a background in this. Is there is good laymen’s book to understand forecasting specifically for sailing or in general. Or are you writing one
@@TheOKellys given that a sub needs to come up for fresh air i would argue that weather is even more important than a vessel that is bobbing around on the surface. just sayin
Great vid, Nick. Thanks for that. I'm down the learning path with my marine meteorology and finding one area where I'm a bit stuck, maybe you can help. Can you suggest a resource for learning more about the impact of upper atmosphere interaction with weather systems, specifically the 500mb level winds? I understand the 3 dimensionality of the nature of the air stream and the divergence/convergence with low/high pressure systems, but how do we use that to anticipate whether a system will intensify or be stable? I have Steve Dashews Weather Book that discusses it, but that's about it. I use earth null school for watching the air stream at 500mb and how the circum-polar lobes extend into the 30 latitudes, but I don't get the "so what?" yet. Do you know where else I can read on this topic? Much appreciated !
Nick! This episode is gold. Thanks for your hard work and knowledge. You're THE guy to do this kind of video. Please let us look over your shoulder in the future as you consider the weather on future trips.
Thanks for this video. I am going through the whole 'collect all the information' phase and videos like this are extremely helpful.
Glad it was helpful!
Must admit that a lot of the info (especially the interview portion) was over my head as not educated enough on the topic to follow! I would love you to walk us through some passage planning scenarios using predictwind and your thoughts process as you determine whether or not to go/when to go.
I'm interested in really long passage planning, like West Coast N America to S. Pacific. Is it even possible to plan that long range? Do you just sail and tweak your routing as you get updates?
@@benlindner5285 Quote you ; " Is it even possible to plan that long range?"
If possible, I would harbor hopping, and make passage planning decisions as you go.
Other than that there are the recurring patterns.
Summer weather is better than winter weather.
There is a cyclone/typhoon/hurricane (⇽ those words have the same meaning) season, and the monsoon season as well.
I’ll try to do more of that. There is some passage planning in some videos from a year and a half ago....check the channel, I think the thumbnail on one of them is “Is you go How Fast?”
Yes Ben, on long passages, you wait for the proper time of year when average conditions are most favorable, then you head off with a good window and tweak along the way.
YES YES YES, Please give the break down as if explaining to a (idiot) child. lol... Very Tough digesting this when not familiar at all. Thanks my friend,,, LOVE the content!
Thank you for a very informative video!
All complex systems are interesting and it's easy to forget the knowledge required to understand them, whether it's weather, a stock exchange, power grid distribution or fluids in a jet engine. Thanks for sharing!
This is the best video across the platform that I’ve watched about the subject by FAR. Great job Nick, Fair winds for us all…
This is the video I've been waiting for, knowing that you're a meteorologist. Fantastic job, great information, well presented! Thanks!! [Edit: forgot to mention: Loved the intro talking point about the dynamics of the two largest fluids on earth. Nice perspective!]

Weather is never a constant in the power of mother nature is always awesome, so thank you so much for doing this video
I’m glad Jordie. Jack is a good guy. Could geek out with him for hours.
I guess I need the Weather Interpretation for Dummies package - The one that comes with the dartboard and darts.
I can recommend a couple of older books that are useful to cruisers that we have found helpful:

Overly technical for me, but I'm sure it's a wealth of info for those sailors
able to use the apps and tools.
Judging from that interview I think Nick is in love! Definitely a Bromance going on there :)
lol
This is a much needed amplification of weather tools available to sailors today. Personally, I would put that information ahead of GPS based navigation when off shore! Well done!
Keep this coming. Ventusky and windy are windy are great! I’ll pay for apps when I start going offshore. Love this info. Keep it going
Great video. We have used Predict Wind standard for cruising from Pensacola to the Keys/Bahamas for the last three years. The passage planning is great for picking the window (from four sequential days). After picking the day, you have the four models to review for the passage plan. (The CAPE model is also helpful to forecast the potential convective activity.) Predict Wind is very accurate and it's fun to compare the models along the passage.
Thank you for this “deep dive” into what goes into forecasting. Despite the complexity of dealing with so many variables you make it easier for the layperson to understand just what goes into accurate modeling and forecasts. Thank you again
Great tips. I’ve always had a fascination with the weather and the sea, and even took a couple of meteorology and oceanography courses in university when I was attempting to steer myself for a commission with the Air Force 10 years ago. This really puts in perspective just how little I scratched the surface, but I may just get some more courses under my belt for better understanding the nuances of forecasting from boundary conditions. Thanks for the resource recommendations!

We always sent him a nice 'stipend' every yr. Thanks for this vid. It's excellent to have an experienced users perspective.
Best sailing vid I've seen in well over a month. Very informative.
i watched and listened twice and now realize that i need a weather terminology dictionnary, so if this is the intro to weather mapping, weather 101 will be most interesting (i used will be) , because im hopeful. Just noticed that your eye has completly healed, im very happy about that although i kinda miss the pirate patch, and lastly i miss the yatch rock, great work, stay safe.
Saw the beginning and thought that looks like the PNW coastal range and sure enough... Fun discussion on the weather app and models at the end. Very valuable to get into the geek level detail questions with the designer. Having sailed in the sound and Hood's canal the thermals are always a thing. Sailing near land mass especially with mountains and the cool water below you learn quickly to pay attention. You can run up/down a coastline avoiding general offshore wind/current trends if there is a local variation that is favorable. This is also true on the east coast where I am now. I get interior wind patterns plus thermals until I get closer to the ocean and then there is confused wind and then the offshore trend dominates.
Absolutely awesome. Thank you for going so deep into weather. That helped us understand weather so much better.
Thanks
Timmy
As others have mentioned, would love to see a "weather 101" episode or even mini-series. From a theoretical introduction, to global systems, to the effects of local terrain. I wish I could look at the jet-stream-level map and have some idea of what local effect that will have.
Well that was fascinating and underscored how little I know about the weather or the wind models (Predict Wind) I use. Learning more will become another of my winter projects. Thanks for doing this.
I watch you guys, and I watch Delos. I really appreciate that you don't try to imitate Delos. I watched two episodes on another channel, and they even danced around to the Delos theme song. I love what Delos does, but I envision myself sailing more like you guys. Love these in-depth discussions of sailing topics. Fair winds and following seas!
Thanks! I don’t think we’d do a very good Delos. They are way cooler than us. Lol
@@TheOKellys Way cooler than this old dog, too. And I'm good with that.
Wow, a lot to digest. And the comments echoed many of my own thoughts and questions.
Now I realize I’ll need to budget time (learning curve) and money for one of the most important ingredients I’m seeking when sailing offshore... Good Weather!
It's a huge subject, but it is literally the whole ball of wax in terms of good times vs bad times on a small boat. Or any boat.
Thanks for this, Nick. I hadn't realized that there is a free level of Windy. I just downloaded it, despite not having a boat yet, to flesh out the information for the typhoon season here in Tokyo. It's fascinating to see the winds in Windy and compare it to the track and forecast discussion on CIMSS Tropical Cyclones.
Nick, thanks for all the amazing content! I'm reading your book right now and it is great. Keep up the good work.
Awesome, thank you!
best weather video for cruisers ive seen - bravo
Weather novices have been educated by masters in this video, for which I sincerely appreciate and thank you! Perhaps this is an intro to a few weather classes by our favorite offshore team.
Would you consider minimizing our weather naivete with a walk through of a route planning through interesting patterns?
This long awaited video is awesome!
Thank you
Again thank you very much for the added information I learned more today than I have in years about the weather
You're welcome for clicking. :P I would love to see more weather related sailing videos and you are the perfect person to serve them up!
Ditto! A cruising meteorologist!
As a pilot, you use all available weather tools, and in my opinion you can't ever learn enough on the variables of changing weather, wind and clear shear.
Thanks for sharing this info as I live just a stones throw from the ice near Lockwood Folly inlet, NC coast.
I will explore the mentioned programs.
Do a bit of flying when I can as well. Luxury we have on the boat weather-wise is a little more time to consider things, usually less risk of icing, and with Clarity....unlimited fuel.... :) Fly well my friend.
Thanks Nick, great review of Predict Wind, I have downloaded it and use it. As a retired U.S. Army Intelligence Officer we briefed commanders on weather effects on battlefield operating systems, terrain, flight and and of course troops on the ground. As well I have a minor in geography from Southern Illinois University which had a weather component to it. I am a bit of a weather nerd so, I love what your are talking about and understand just how important weather data is before you go on voyage across the ocean. I am coming to you from Turks and Caicos, Seven Stars Resort and Spa. Doing some Scuba tomorrow and am looking forward to getting under the water. But had to look at the weather data to get back out on the water... Good look to getting back to Clarity when you do. Be safe and we look forward to your next videos.
Hey Ron, I (Nick) was a geography undergrad after my meteorology program was cut by Measure 5 legislation. Love geomorphology myself. Enjoy T&C! Say hi to the fishes for us.
excellent my wife and I are going to go board our first sailboat next week and sail it down to florida from new york, very nervous your video helps alot with the detailed information you provided. Thank you very much
That’s quite a voyage! Fair winds!
Another great video guys. As always, I learn a lot from watching your channel, so thank you for taking the time to produce these super informative videos.
You know a video showing us how you read the winds and seas on your devices for short and long distance trips would be pretty cool IMO :)
Very well done thank you. I took a weather course in boaters university and this helped connect some dots.
You knocked this one out of the park. Excellent. Thank you.
Thanks for sharing , love these types of videos, Note that Ventusky is now $2.99
Hello Nick
If there is a library of must keep must watch videos, this one will be number one.
That was one of the most interesting videos I have ever watched. If I was a fan of meteorology now I am addicted.
Thank you , amazing knowledge.
Cheers from NYC
Thanks Carlos!
Fantastic information! Thx to you for sharing your knowledge, insights, and experience. Cheers.
Thanks so much for this well produced and structured video. As a long time pilot I have slightly more understanding than the average Joe (only slightly) but of course my predictive capacity is improved by the average very short window needed for a safe flight and restricted to the areas well above the surface. People rarely appreciate the incredible complexity of these models and the dependency on limited data collection ability especially offshore! I have only sailed offshore a few times and that was a number of years ago when these models and apps were not available. It was hold your wet finger up and look at the wind vane and barometer. Scary stuff sometimes. Thanks again for the video and the info on the available predictive software that can now significantly improve both my knowledge and my peace of mind. Stay Safe.
I’m hoping that these weather/sailing apps for cruisers evolve to where Foreflight is! Amazing power with these tablets in our hands
@@TheOKellys Absolutely! It is wonderful the age we live in with the rapid advancements. The old Arthur C. Clarke adage holds true, "Any sufficiently advanced technology will be interpreted as magic to the natives". Welcome native!
This was a very helpful video. I had seen other videos on weather apps, but not with this kind of detail. Thank you.
Another fantastic video, I’m so happy that you Able to get the interview and you did an awesome job. I’d like to see you do more on this type of video in again thanks so much be safe and take care
I'm looking for my first sail boat now and am studying all the info I can find. Wanted to thank you for all of this and have been following you for a bit now. Maybe someday ill see you in a warm sunny harbor in the Caribbean.
Your obvious passion for sure. Bit above us mere sailors - would be nice to see a series of short videos on a specific decision making process given a set of conditions. Because of this ... we decided to do xyz. Thanks for the great content.
Good idea. When we get underway again on Clarity in a couple weeks, I am going to do a bit more of that...or will try. I do get the feeling that this is boring stuff for a lot of people...but it shouldn't be...absolutely critical to good trips.
@@TheOKellys Don't believe sailors find it boring at all, but short takes on how you process the info for a voyage is practical and we can all learn from it.
As a fellow met, I found this video informative and entertaining. People would be surprised to find how many mets are unable to communicate wx info to the non-met people.
It is a really fine line to walk, is it not? Too little detail and it is cloud talk, too much and it is matrix algebra and PDEs. Lol
@@TheOKellys Not everyone enjoys reading Holton :) The tools nowadays make it quite easy for non-mets to make informed wx decisions.
Weather Professor Nick, great video, excellent guest, alumnus and sailor, another weather headjust like you, thanks this information and insight makes us all better sailors! Love it man! Thanks for sharing
Capt. Prof. Nick Esq. LOL. Thanks DJ!
Excellent and very helpful! I planned on a GO and PW so it is nice to know I am on the right track. I sail for the S. Pacific in March '21!
Hope we see you out there Ben!
Well, that was just awesome. Thanks for the info. I find software generally easier to use once I understand what the developer's intentions are. So getting it straight from the horse's mouth makes predict wind's features and foibles far clearer. To me the key was that it's really about showing the range of possibilities to be prepared for.
exactly. anyone who says..."hey the model was wrong"....just doesn't understand how models work or how to forecast. For the foreseeable future, a human being is required to make a good forecast. That will change eventually, but for now....a (skilled) person needs to know the limitations of each model and the range of possibilities. This video wasn't really about forecast, but maybe that's a topic for another video.
@@TheOKellys yes please!
Wind guru is fantastic!
Ok, now I know I need to study more on this... Thanks for the great info.
Excellent Info. Thanks so much for doing this video. Well done!
Great video Nick! Really appreciate the drill down on weather and route planning. Might there be a book or video course in the future?
I need more time than I have. I need another Nick....who will work for what I pay myself. lol
Thank you Nick for these weather videos. Very well done, informative, and timely!
This video was great!!! exactly what i needed for my up coming trip up the west coast to the Dalles.
Great video. The interview took me back to discussions in Chem Engineering classes
Nicely done! As always, very informative!
Appreciate it! Glad it was helpful!
Great video thank you. Lots of information that i was going to research.
Thanks for the info, just downloaded the Windy app
Nice to see you geek out👍. Great job.
Thank you, Master weather wisconsin pro. Actually, just thank you. Best feature seems to be wind and tide option. Thanks for sharing.
Nick, great video about life importance matter for sailing. Please keep including the short one minute introduction to weather forecast and rout with clouds type identification on each sea passage. It makes a useful practice.
You got it!
I can recommend a couple of older books that are useful to cruisers that we have found helpful:
"Mariner's Weather Handbook" and "Surviving the Storm", both from 1999 by the Dashews (Steve and Linda). The latter should be in every cruiser's library. Although we have some nicer tools now than weatherfax (still important), his advice and case examples are still good, imho.
Weather geeking! Nice!
This is a great video, I think ill need to watch it again or maybe three times.
Best book I've ever found on weather - Modern Marine Weather by David Burch, recommended by those who have gone before me. It blows me away how much more information he provides and in such a way that if I read it some of it a few times, I comprehend. What a great video you did. Really enjoyed the interview. Q: what does it mean when a model "blows up" or "runs away"? I really appreciate you taking the time to do this. I have started the PW / Iridium Go purchase process no less than 3 times in the last few months and then pulled back. I'll check out your affiliate link.
There are a lot of positive feedback processes in the real atmosphere...”nonlinearities” we call them. Too many and too detailed to get into here. But bottom line, in the real atmosphere, little things can have tremendous effects. So the geniuses who build these models try to capture these nonlinear processes, but they can be “too sensitive” in some circumstances and the model solutions get out of control with feedback loops sometimes. That’s what we mean by blowing up. Now this happens with all models all the time, and so there are “smoothing” algorithms applied at some grid scales and time scales in an effort to keep things reigned in....but that can go too far as well.... So the best models for any particular kind of initial conditions are best at “attenuating” these nonlinear processes realistically. It is a very difficult task for any model.
Very informative. Would like to see you do a follow-up video focusing on voyage planning using the apps. Really like how professionally you are invested in this topic. Really showed what to expect from these apps. I want more! Saved in my favorites.
Thanks Jamel. Will try to integrate into the vlogs this season
This is very interesting! Since moving to the South where I am now in Tornado Alley and tropical storms, I have really taken an interest in the weather and what it is doing, so I know what to expect. I consider this to be my training! LMBO
Thank you for doing this episode I found it really helpful and informative.
Excellent video - thank you! Unless I missed it, I don't think you mention the free portion of PredictWind, which is all we use. The PWE and PWG models are available down to 8km resolution for free on both phone and web/laptop.
Right! And really, that's all we need. We go Pro so we can get downloads over Iridium.
I'm fascinated with atmospheric science and would like to learn more about forecasting, without going back to graduate school. This video was very helpful. Do you have additional advice for developing a theoretical underpinning of forecasting?
Great episode. Very informative. I wish all of my hobbies were not weather dependent (sailing, flying..etc.). I'm curious if you've seen forecasts that were way off....so off that it was dangerous?
Yes, sometimes. There have been several documented cases of "bomb cyclone" formation which all of the models miss. We were actually caught in one of those staying in at Lucaya many years before the sailing adventures. Mostly though, I see models overdoing it in some frontal situations and "overreacting."
Fantastic video thanks Nick! And yes, the Aussie accent is the best 😂😉
Fantastic, you should post this in aviation blogs as well.
Also for your pilot friends, what can you pull out of ForeFlight useable for sailing?
Man, it is completely different. Everything in aviation is soooo much more structured, from nav to weather to planning.... If people had to operate boats like you do planes, no one would sail.
I agree on the structure comments by Nick! When I was just a VFR (visual flight rules) pilot it was more fun. When I became IFR and type rated in a jet I was safer but flying became less about flying and more about procedures and weather.
As far as Foreflight, there would be (as Nick stated) more data to add to your data pile. But for what (I think) you would get out of it and for the effort likely a minimal benefit.
So for me 2 thoughts here, if conditions are dicey enough to substantiate digging into foreflight one probably should make the “no go” decision and wait for a better window. On the other hand, if I was stuck in a really bad situation I would use any data available.
Lastly, one thing I find very useful in aviation is Pireps. With weather forecast already being analyzed I find actual accounts of reported conditions along my route very helpful. In aviation We have such a shorter time of exposure. I’m not yet experienced or have a solid education in weather for sailing.
I see that many Pireps my be used in the models supplied now. Could be a benefit to have current reports plotted on the map for consideration?
Another thing aviation has available is routes used by other pilots recently. FLTPLAN make suggestions on routes base upon other flights made recently. Possibly this is a consideration already given inside PredictWind’s routing? Idk. Nick finds these things out!
Great video and thank you for sharing your knowledge with us. I’m not ready but I can promise I’ll be watching all your video’s on weather and gaining more knowledge until I’m more confident!!
ForeFlight is an awesome app by the way. 👍
ShipReps are a thing already, and I talked to a gent from NHC about a program to incorporate more of those from small vessels. No timeline, but that really will make a difference. Suggested routes....now there could be issues with that as bottom contours change a lot over time, especially in shallow areas. Not so much an issue in the skies....
That will be very useful to everyone but possibly more value to someone like me learning. If I’m lucky enough to experience doing a crossing it would reassuring to see actual reports substantiate the weather I’m pulling down.
Actual observations are valuable and mostly very accurate but caution still needs to be taken. Example: I was descending into Dallas, was given by the tower while on final, the aircraft just front of me were reporting taking on ice from 2500’ to 2000’ melting and shedding off after descending through 2000’ and before landing. We took ice starting at 2000’ and all the way to the ground. Landed with ice.
Lesson: information is good but still not guaranteed. This was maybe 5-10 minutes difference in time.
It took me years to figure out all the functionality in my GPS. I think the same will hold true for these weather applications.
I still think it would be great to collaborate on trying to find a format to do a primer on basic weather. I’m reminded of a time when my son (I think he was five at the time) asked me, “mom, what makes wind?” My inner weather nerd came out and answered, “unequal heating of the Earth’s surface.” My son did not ask me weather questions again for a couple of years. Is that a mom win or a mom fail?
Great vid this week. I always enjoy the weather ones!

What a great video, Thank you for this!
Hi guys! Thanks for all your usefull content in your videos. I see the only main difference between the standard and professional package is the Ocean/Tidal Currents feature. In your opinion, is it worth paying double for that one feature? (a circumnavigation is in future plans)
Hey there! Other difference is the 1km resolution model data and more extensive gribs from ECMWF, including wave model. Both the ocean and 1km data is going to be very hard to access offshore due to file sizes. However, if you are going to be operating around strong currents like off E coast of USA, SE coast of Africa, N of Australia, that can be very useful with passage planning. The high res model data is also most useful around land masses where cell signal is going to be more realistic. So yes, you are paying a lot more, but there is also a lot more potentially useful data. If this is all new, go for Standard and upgrade. If you are into serious offshore prep already, I do think having all the Pro data is helpful.
Really thoughtful discussion
Great stuff Nick! I'm sure Megan appreciated a week off from the limelight. ;o) Next week, sewing machine comparison!
Thanks, super interesting and useful - and the bromance, funny 😆
Great informative video and thank you.
Very useful information and once gain a great video.
GREAT video! Based on your experience at what duration of passage does adding Iridium or other satellite service become very important for updating weather while underway? A forecast obtained at departure might be great for the first two days, but then accuracy would progressively decline.
We feel pretty naked without satellite connection for more than a couple days. But it depends on the time or year and location. In the trade winds, I’d probably feel ok with a three or four day passage without satellite, but in the substropics or mid latitudes, more than 72 hours without weather would bother me a little.
This is a fantastic video. Thank you so much.
Great video Nick!!! I love the background #missyousugar
In a world of vlogs in which everyone seems to think the world wants to watch a sexy young woman in a bikini pull up an anchor (and they may be right) this is refreshingly educational, relevant and helpful. Very well done.
I have predictwind and sailflow, both paid versions. I find Sailflow more accurate when using local/coastal short range forecasts for local races, mostly on Chesapeake Bay. Sailflow mid Atlantic 2km model is usually very good for short range.
For route planning, I like SailgribWR, paid version. It's sort of an Android version of Expedition routing and navigation software on Windows, albeit much slimmed down.
Really? I will look into the Sailflow. The WRF may have made some strides over the years. It was a hot mesoscale model for a while in the 90s when developed at NCAR. If Sailflow is running nested grids based on it, it must be quite computer intensive for them. Are they running it just in regional grids?
@@TheOKellys can't comment on what sailflow is doing with the model, just my experience in using it. It's usually really good at local forecast, typically within a few hours of the race, for a race lasting a few hours or a day. This past season doing Wed evening races off of Annapolis, when we can get late afternoon showers or local wind anomolies it has been really good. Predictwind 1km forecast is great for overall trends but seems to smooth local disturbances out.
Overall though, I check both PW and SF all the time and keep my eyes open on the race course. Neither seems perfect, gotta make judgements with both as inputs.
I did review it for the vid, but not the paid version. The free version did not impress me. So thank you. I will look further into it.
I also found GRIB US or UGrib Very useful and helpful as a weather tool years ago.
Super helpful, thank you!
My network (ham) has some old salts trying to deliver the best weather we can find. We read it as part of our "Chubasco" network, most of it is geared for the Baja area. But, we will do "fills" for someone in a different area. We are on at 7:30 am 14:30z right now , to change an hour,, soon. This is for those who cannot get weather from "cell" signals. We are on 7.192 mhz every morning. We have sailors in Washington, Oregon , and California. If your a ham we are set up to receive even the very weakest Side-band signals with our "relay" format.
I think the future will be in the use of "weak signal" modes. I would be able to transmit to and receive boats From Hawaii east to the shores of California, and they would be able to receive my digital hf signals also. The mode with the most promise is JS8CALL or JS8 for short. The gear is really inexpensive, an HF radio, and a sound card. Many radios have them inside when you buy them, or you can add a Signalink. You could transmit an entire weather forecast fairly quickly and ALL boats could receive it regardless of what frequency in the JS8 40m band they were listening to, and regardless of what speed they were set to. I would receive the slower speeds best, but my signal is so strong I could transmit the weather to their screens at 50 words per minute ! I'm extra class amateur operator N6GRG
One of the big wind events we have to deal with is th PGE safety shutdown forecast. We are going into one I believe tomorrow.. I actually think they missed one, I live right next to the Zogg fire. The wind was coming from the north, a few degrees to the east and I would have been in it.
Then I bet you remember Don of Summer Passage. We relied on him often. Such a kind service he, and now you provide for Mexico sailors. I should have probably mentioned it, but we do carry a receiver on Clarity. We will listen in on the nets from time to time.
@@TheOKellys Awesome, love that we are being listened to. Please consider the JS8CALL as I think it is the future for marine as signals are weak for boats with marginal antennas. Thanks.
Thanks for sharing all this
I am big fan of predict-wind, I use the high precision model to plan sailing on my local harbor.
Weather 4D recently drop Android support as it is not a 64 bit app and google play store has dropped 32bit app. The IOS app is still supported and under active development
Very helpful. A bit of a geeky :) conversation with the guy from PredictWind but very interesting nonetheless. I think an aspect that the models/discussion seem to miss or omit is the effect of bottom topography, ocean current on sea state. I could be wrong on this but I never hear it discussed as a factor in the ocean sailing models. I would love to see a practical discussion of that because sea state more that wind is what makes a passage difficult for most sailors/crews/families. A passage can be great and then a few hours of horrible seas can completely frighten a crew. In many ways the likelihood of bad/short/steep waves is something that can be anticipated by understanding bottom topography. If its anticipated it become less of a "out of nowhere" event. Anyway, thanks for an informative video.
Coastal contour has a much larger effect than bottom topography except with really big waves or really shallow water, at least on the "open" ocean. That being said, I am not familiar enough with the mechanics of ocean models to tell you at what scales these factors become important. What I can speak to is the effect of currents on wave heights. Wind opposing current can make for really big seas if both are really significant and the modeling of these things is still quite course. I expect significant improvements in the coming years as supercomputers become faster and cheaper.
@@TheOKellys What I'm talking about is longer passages over routes where sudden changes in ocean depth would play a factor in sea state. Take for example a passage from Puerto Rico to the Bahamas. The Navidad bank or the the Silver Bank are places that I would avoid in rough weather. I never hear people talk about these considerations in voyage planning. Sea mounts and rapid changes in ocean depth occur all over the place. "Beware the 100 fathom line". :)
@@TheOKellys To follow up - the lovely thing about cruising is going to new places. The scary thing about cruising is going to new places. In familiar places we know where waves or conditions are tough. How do we figure that out in new places. Learning to "read the bottom" is, I think, an important skill in anticipating or avoiding tough conditions. Just my 2 cents worth. Take care. :)
Oh, for sure those are tricky spots. Seems a boat (not necessarily a cruising boat) is lost on Silver Bank every other year. We’ve had crazy waves over seamounts a couple of times. Once was Thetis Bank off Cape Lazaro in the Pacific. Those were unusually large seas to begin with, and the survey of Thetis is incomplete. I know a fair bit about gravity waves, and the bottom doesn’t effect waves until dept is about twice the wave height. However, what does happen around seamounts and other big shoals are strong and changing currents, which like I said earlier, can have a tremendous effect on waves. Yes, the new places and new faces are a big draw for us as well.
Excellent episode! A little off topic but, I didn't know your boat was running for a political office in my area. The political sign on the side of the road said "Vote for Clarity".
Lol. We all need Clarity!
Love this content. It’s great info that seems to be said but not explained on other channels.
I wonder what you think of the app “MyRadar” they have added lots of features over the last year.
Also - do these models take into account solar radiation or surface heating and water temps to forecast? Not i don’t have a background in this.
Is there is good laymen’s book to understand forecasting specifically for sailing or in general. Or are you writing one
Well Nick I have to disagree, the type of craft you have does make a difference....buy a submarine...cheers folks
Lol. I stand corrected! Lol
@@TheOKellys given that a sub needs to come up for fresh air i would argue that weather is even more important than a vessel that is bobbing around on the surface. just sayin
I'd love to see more info on AIS and internet, etc.
Great vid, Nick. Thanks for that. I'm down the learning path with my marine meteorology and finding one area where I'm a bit stuck, maybe you can help. Can you suggest a resource for learning more about the impact of upper atmosphere interaction with weather systems, specifically the 500mb level winds?
I understand the 3 dimensionality of the nature of the air stream and the divergence/convergence with low/high pressure systems, but how do we use that to anticipate whether a system will intensify or be stable? I have Steve Dashews Weather Book that discusses it, but that's about it. I use earth null school for watching the air stream at 500mb and how the circum-polar lobes extend into the 30 latitudes, but I don't get the "so what?" yet. Do you know where else I can read on this topic? Much appreciated !
fantastic video, u are a * Nick, calm and clear explanation of a very important subject , thanks for charing your knowledge
Great info!
Glad it was helpful!
