- We all know that warm air rises, but how does this scientific fact influence our weather and create those flows of air molecules that we know of as wind? In this episode of SciShow, Hank explains where wind comes from, what factors influence it, and how fast it can go!

This question popped into my mind, now I can sleep thanks
James Mariano 😂😂😂
😛😛
Atleast i want the only one, goodnight
yea james Mariano
I’m doing research for the groupchat
I’m stoned af and it’s windy and I was like “what is wind”
Literally me rn deadass
Thats me rn dude lmfao
same 😂
LMFAOOO SAME
Stoners unite !
I know this might seem random, but hear me out. I started watching Hank's material solely to pass basic biology and chemistry. I hated science and I thought it sucked. With the help of Hank's channels, I both passed those classes, and learned that I actually love what science has to offer. Today, I'm trying to major in both neuropsychology and biology. And I'll probably make it. But I'm here to some degree because of help given by Hank. All I'm saying is if you're new to this channel, keep on watching this splendid material. You never know what it'll inspire you to do
Also Khan Academy. When I did Biology in college, I couldn't figure out what my lecturer was explaining. Off I went to youtube and things like the Krebs cycle made way more sense.
Coopdog 😂
Congratulations, you confirmed the uselessness of school today
haha
Thanks for this inspiring message “Lord PussPuss” lmao. If someone with a username like that can study neuropsychology then this channel truly makes anything possible!
I love that this video is nearly a decade old and still feels fresh!
What happens with the wind once it starts? Does it just keep going or does it gradually die down?
+Gage Thomas Of course it dies down and it's never entirely consistent, which is why wind power is such an eyesore folly, needing constant backup power from traditional power planets. Some areas get steadier winds but climate change may well alter that.
One of my favorite channels on TH-cam thank you
Wow, this video was particularly well done. Good job SciShow.
This reminds me of the German commercial, "The Wind". Anyone remember that video?
wow 7 years, but 4 likes
@@endlesssnom and he's verified lol
I think another variable that people miss is the different terrain that is exposed to sun. So the fact that a sunny day hits water but only heats the air a small amount while raising the temperature of complete body of water a few degrees. While the same sunny day hits tar at a parking lot nearby, heating the surface of the tar, the air above it, but not the earth below it. This will create the gradient of heat that may cause wind via high pressure/low pressure.
Same with the difference of terrain of a forest (which converts light into chemical energy via photosynthesis) versus a desert (which just kind of roasts converting the light into heat).
In the absence of the sun, the mass of a desert will cool at a rapid pace while the forest will take long for the heat to dissipate out of the vegetative community.
Adding the variants of terrain, the rotating earth (day and night), the earth's tilt (changing seasons), the current humidity (the sun being absorbed by cloud versus hitting the earth's surface): All of these factors can create a wide variety of unpredictable weather. Even small shifts in the exertion of stored energy via human/animal motion or the combustion of gasoline in your cars can have an impact on local temperatures and thus climate/wind on a larger scale. So many factors ensure that weather is never repeated but there are still patterns that can help predict to a limited degree.
Who else is here because there science teacher didn’t feel like filming themselves in the middle of a pandemic? Just me...ok. 😂
Me
Same
MEEEEEEEE
Long have I pondered about this question.. Thank you Hank and your team for this episode.
I would absolutely love to see a video on the science of learning! There is so much more going on in the brain then we can see (obviously) and there is more to do than simply be curious! Here's to hoping! And as always, thanks for continuously providing awesome videos! -Alicia
You know what would be cool? Crash Course Weather!
Okay... cool might be pushing it, but I'm sure there would be some temperature involved :)
I was just thinking the same thing! Ohhh how I wish they would make scishow weather, I’m such a huge weather enthusiast...
Wow, many years ago Hank used to present SciShow while he was drunk apparently.
2:16 Yay for mentioning Mt. Washington.
I've been on Mt. Washington a few times. One time was when I actually hiked up Mt. Washington.
This is great! I've pondered wind since as far back as I can remember, but for some reason never got around to researching the processes behind it.
Thank you! My nephew asked me what wind was a few days ago, and I had no answer, well no good answer. Problem solved, just make him watch this.
U initially told him it was what happened when u ate too many beans didn’t you lmao
_♪...baby don't storm me._
_Don't storm me._
_No more.♪_
Good job Hank, Love your work.
always an excellent compilation of knowledge ~ thank you :o)
suggestion (if it hasn't already been done): what makes you itch, and why does scratching help
@@irl_jasmine Shut up....it does help. We aren't talking about fuckin poison ivy here, we're talking about random itches
@@MegaBajojou answered after 6 years damn
Scratching dont help
@@caydenneeley2718 wut
It's so nice to see the numbers/stats in this show in meters and celsius =)
Thanks!
It’s not so nice when they don’t also include customary units alongside it!
Oh thank you so much Scishow! I always wanted to know about wind!
If it means anything to you, I am so glad that you presented this video using metric units. The flow of the video wasn't ruined for me personally and for that THANK YOU :D
wind goes to the right ? Wind goes to the left?
Right and left when you're facing...what, exactly?
He said right in the North Hemisphere, and left in the South Hemisphere, so I assume he simply means east and west assuming you are looking at a eurocentric map.
I think you mean a north = top map
facing the poles i think
From the same reference point.
Great conversation to read while eating airheads :D
Thank You so much, you just basically summed up the past 5 weeks of my Geography course! Was a little fast, but I'm definitely keeping this for exam revisiom next summer, haha!! :D
I thoroughly enjoy your ability to present.
I find this episode a bit too shallow. A few more details and a bit more depth would have been good.
Like what zones exist, how clouds rotate, jetstream, maybe some things like that.
This did my nerd heart good.
You're a genius. I wish I could be as animated as you are. Keep up a good job!
Funny how I already knew most of that but only really understood when you explained it in this video... in a language that's not even my own. So, congratulations I guess, Hank, for your talent at passing on knowledge and keep up the awesome job. :)
Woah, was the same with me.
I knew it already, just needed an explanation, not my language
Damnit America, teach the metric system.
they do teach it. they just don't use it.
Well, I meant use it. I live in America and I hate not knowing how to use it practically, if you get what I mean. Like, I can say, "oh that's about a foot" but I can't do that with anything metric.
Zicrixdoesart A meter as almost the same as a yard, to put it in perspective. Just be like 300 Meters per second... about 900 feetish. Very rough estimate but still.
if you have a smart phone, get an app called the 'convertpad' it'll give you exact conversion in all kinds of measurements. I do mean ALL kinds, viscosity, speed of light, fathoms etc. So hopefully you can get more of a perspective of how we metric people's see things :P
NonTsutta! America does teach the metic system... I was learnt the metric system in 3rd grade for math and science. People do learn it though they normally forget it because its not the main measurement system we use.
I don't like the idea of using metic for everything, decibels screw me up. I tend to mix metic and important.
Also we do sorta use metic, water in my aria is measured in letters.
What is wind?
Baby don't blow me.....
I know this was five years ago. But that was one of the most stupid jokes I've ever heard.
@@MegaBajojo 🤣
Skoodle wind: Baby don’t blow me
Hurricane: Baby don’t hurt me
Meteor: Baby don’t kill me
End of the world: baby don’t destroy the world
End of the universe: Baby don’t make anything exist
I just learned this in my science class last week but it's still nice to see these videos
What I like so much about Sci show is that they make very interesting and entertaining video, but compared to other channels (e.g. Vsause, Sixty symbols, Minute physics) Sci shown makes so many videos, so fast. Keep up the good work! Love this show!
"To the left" or "to the right?" Ummm...what? "Left" and "right" depend on one's orientation. How about "westward," "eastward," or some other absolute(ish) direction?
+rchandraonline Consider the swirls as clocks that you're watching from above (that's one's orientation) and I think it might be easy as pie to understand. And more absolute than any other thing.
+maaskeimorgen , that orientation is a chosen orientation, and if utilized, ideally should be stated and not just assumed. If clouds experiencing Coriolis force are viewd from the ISS, they will rotate either clockwise or counterclockwise (not right or left mind you), but the same clouds viewed from the Earth will have an apparent exactly opposite rotation.
In the video, straight arrows are drawn which imply east on the top and west on the bottom, but only if one assumes north is at the top and south at the bottom. Such assumptions also give rise to phrases I've heard recently, like "above the euqator," which I thought atmosphere and outer space were above the equator (or any other reference point on the surface of Earth).
All I'm asking for is a more precise description with fewer implications and assumptions.
i want to fly a kite on mount washington. in the dead of the winter. and put that shit on youtube.
thank you this helped a lot for my earth science class!!
Though I already knew most of this, I still found it really fascinating :P
What is lint?
I only clicked on this because I can't stop farting
I heard you're farting non-stop for three years
@@scorpionking7510 haha
Aha I'm learning about this stuff in class! And I enjoyed watching. Thanks :)
Good timing, the weather has been very extreme today :) trees knocked over and damaged buildings. Can't even go outside! So I sit here and watch SciShow explaining wind whilst waiting for the wind to go away.
So who here is watching this for school during Corona
In out of school but with the covid, I've spent more time outside (front yard, backyard) then ever before and always wondered.
This guy makes no sense
thanks hank for keeping me up to date with current events and teaching me in an entertaining way about how the earth works.
You just answered a question I have been asking since I was a kid. THANK YOU.
You should definitely follow this up with a video on the chaotic nature of turbulence and how we are trying to understand it, i.e. the Navier stokes equations and how we can model flows computationally.
I LOVE WIND--all forms of it! When it's a windy day, I make sure to go outside to embrace the joy out of the wind. I live in NYC and we have all speed of it.
Thanks for all your videos. I use them in my science class. The kids love them!
That short animation with the air molecules used the least amount of molecules necessary to illustrate the point and the percentages were spot on. Good job
SciShow makes stuff so easy to understand
Thank You For Your Knowledge
We had crazy wind. Thanks for a great video I've wondered this for ages
Those wind puns were hilarious, thanks for the laugh!
so helpful for my class, thank you.
ohyea, i remember hearing about those 10 years back in school, i suppose never using/hearing them makes them rather easy to forget
awesome vid the class liked it
crazy thing:sat at work when the thought occurred to me: what is wind anyway? later when i logged on to youtube this video was up. Sci-show is awsome
Interesting idea this all seems very neat
i love this show. reminds me of inquiring minds. good show from the 90's
Im so happy that this video is a thing cuz Im so curious about wind and that meens u get a sub
i've climbed mount washington a couple times now. Indeed it has the most unpredictable/dangerous potential weather in the world. A few times we weren't allowed to continue the climb to the summit and had to turn back.
i have brought this question up to myself like 50 times through my life and never remembered to look it up, I'm kinda proud of myself for coming to the right conclusion by myself
Beautiful.
Dude I'm in the Netherlands right now, you have no idea how timely this episode is.
Are you kidding. This conversation gust lifts me up.
They are old units used to measure property boundaries. I had no idea what they were until we were looking over a deed in Canada this summer, and I saw them listed and had to look them up.
Idea for future topic: "Creating a standing wave in an open tube - How music is made with wind instruments (woodwind and brass wind)"
There are so many people swirling around this topic... it's blowing my mind
0:24 basically says wind come from flowing air which is basically wind. So tell me what is wind
this helps me in my online and physical school thanks
great work man got an exam tmr on atmosphere i feel ready will report after exam
Wow, I was just wondering about what wind is yesterday with the storm in Europe, and then this video shows up :O
Ive been watching for a while now and have been really enjoying it....I would like to ask a favour? I have epilepsy and will live with it for the rest of my life. I was wanting ti know if you could do a show on epilepsy and the effects on the human body and how it is caused in the brain aswell as how they sometimes cure people who have it. Thank you and hope to hear back from u soon
I like how you use the metric system!
Hank, you sure can deliver a well spoken speech being highly time efficient.
*Imaginary* hat off to you.
I know right! I just can't wait until this whole thing blows over.
A wind fact I find fascinating is the winds on Mars when the seasons change. When one of the poles warms up, dry ice in the ice cap sublimates and essentially makes a bunch more air, and creates 400 mph winds. The atmosphere is a lot thinner than ours though, so that speed doesn't necessarily equate to the same strength as our winds, but still, that's pretty fast.
ty fairly much im on a progect with my class and this help really much ty
a couple of guide book of Sweden I read referenced them. You see, in the North of Sweden, where there are few settlements, they put distances on street signs in miles, which can create problems. To find references, it might be easier to search for "Scandinavian Mile"
No way! I live 50 mi from Mount Washington and have hiked it quite a few times :). But not super surprising the weather up here is no joke.
What he was referring to was a Scandinavian mile,(look it up) which is 10 kilometers. We Scandinacians tend to forget that we are the only ones who use that term since it's so handy. Instead of saying "I have to drive 200 kilometers today" you could just say "I have to drive 20 miles today". See? It shortens everything down to manageble numbers.
Really fitting, as we had a storm un Sweden last night..
Perfectly logical explanation.
The second verse of "Home on the Range" describes wind in Kansas as a "zephyr." Zephyrs are defined as a "light west wind." I've lived in Kansas for 30--ish-never-ask-a-woman-her-age years and very rarely do we have zephyrs..Hot wind out of the south, yes. North freaking freezing winds sure, Tornados threatening to send us all to Oz in March and April...yeah...but zephyrs!!?!? Crazy singing cowboys!
Good video, Mr. Green.
Hank can you tell us more about whether/how we can travel by jet stream?
That's the thing, sometimes really simple and seemingly obvious questions can lead onto bigger things not thought about in the same way. On his original question for example you could always lead on by talking about the complexity of different atomic structures and density etc.
i had geography today on this exact subject and i didn't get it. but now i do thanks scishow
Thanks for the informative video that I was watching together with my wife. But she still a little skeptical about the science.
Well this is ironic, we had a storm just around the time this video came out, took the roof of one of our buildings, at least now I know why. Thanks Sci show!
I have hiked mount washington 5 times. It is always windy up ther, at least 40-45 mph on a good day
Hey can you do a video on this COMET ISON thing coming our wayy!!
This is one of the topics of my exam tomorrow! I live in Germany and it is just soo weird to hear everything in English we discussed in class
Awesome show as always. Can you do an episode about Protein?
Thank you for taking the time to respond. I am aware of this. I just think it's a cool question for them to address for the general public. Have a great day, Staffblast.
The PUNS THEY ARE AMAZING!!!
Yayyy! A video on real, testable science!
Alright, you summed up my College Oceanography 101 Chapter 6 in 3 minutes. Impressive!
What about a video on the Ekman spiral by the Swedish physicist V. Walfrid Ekman.
