- What is the jet stream, where is it located and how does it affect our weather? Wet or dry summers are all to do with the positioning of the jet stream. In this video, we look in detail at the Polar Front Jet, which strongly influences the weather over the UK and Europe.

Best explanation I had ever.
no
Think u r suffering from madness
@@suvarna_14 😂😂
Not true
This video must be seen by all meteorology amateurs. It perfectly explains all that is necessary for understanding the mechanism of weather (about which i have been confused for years)
It is seriously complicated for a newbie, but this looks like a great channel from which to learn.
We all came here for Jetstream Sam
true
Jetstream sam is a brazilian who can double jump
Monsoon is an emo who ate the chop chop devil fruit
@@RedNumber19hello
Thanks for this information! My memories were really broken.
God bless this video being accurate, until now the truth went unspoken!
This is very well done.
The explanation is scientific enough yet not too difficult to understand.
that is why I love this channel
@@aminaV_ can u tell me what is there in video
And yet i didn't understand it mostly because it's 1 in the morning and i should get some sleep
I thought Jetstream was a brazilian samurai who was a memeber of wind of destruction
What an amazing explanation, thank you so much!
I've finally wrapped my head around why the jet streams exist.
This video created a jet stream of knowledge going directly to my brain
Great explanation thanks. Your videos help me a lot for my ATPL exams :D
did you pass your exams yet captain
Jetstream sam
This just saved me from failing my Meteorology final! Thank you Met Office!
Did you pass it?
Chris Johnson I did!!!
Wonderfully lucid explanation of something that had been a mystery to me. Many thanks!
Wow. Very well explained. British have the best Met Office.
This is the best jet stream explaniation in the whole TH-cam, thank u so much!
3:00 the stronger the temperature gradient, the stronger the jet; jet is stronger in the winter than in the summer as the poles cool, increasing temperature contrast
3:15 jet further from pole winter, closer to pole in summer
3:50 wet summers in the UK if jet stream remains to the south of the UK
Obviously.
Extremely useful, accurate explanation !!!!! THANKS A LOT....
Perfect level of explanation and excellent visual demonstration, thank you for the video 👌
This video is excellent. This is exactly what I wanted to learn.
Probably the best video ive watched on jet stream
Wow. Just amazing. You Never disappoint.
Very informative and I learnt a lot from it.
These videos of yours are absolutely brilliant. So detailed and clear. I just got interested in the weather after reading the excellent book by Oliver Perkins, and these videos are helping a lot in understanding the scientfic background to the weather.
sam
Clear explanation with animation. Thank you.
Excellent explanation, very well done! Thank you!
Extremely good. thanks!
Excellent explanatoin of complex subject: THANKS!!
great video, good explanation. Thank you!
Every child should learn this, it is amazing to see the Earth's motion and winds in action. Great video. Thank you.
Very informative, thanks.
Thanks teacher
it helped me a lot to understand jet stream
superbly explained..... thanx a lot
Best explanation mam..hats off u r best in the world seriously.. no body can teach like this ..u have us ur wisdom and much more...much overglwhelmed
Well spoken and easy to understand video.
Great explanation. Thank you.
Thank you❤️
From Sri Lanka 🇱🇰😍
Really helpful . Much easier for a layman to understand .
I always wanted a good explanation. Thank you
Fantastic explanation I think the best one I found on the web
Powerful Explanation
It was a great explanation thanks a lot.
Good thing about the video was covering all the causes and effects.
Awesome explanation...!!!
Ohhhh lovely explanation...so many doubts cleared in single video..Thank you so so much..❤❤
Mam, you cleared my doubt. Thank you !
excellent! thank you
Great explanation, thanks so much
I still feel like I can't understand 😔
Superb...😁😁 Explained
Fantastic explanation. Thank you very much indeed. I will now be able to hypnotise people with this knowledge.
Nice well explain
Great Video! 👷
In Grand Forks BC @ 2013/4 looked up miles above a very super high cirrus clouds, saw this snail trail of clouds barreling along. Remember I got by binoculars out at the time. Must have been miles wild, like clouds, I could see right down the valley too because it runs oddly east to west. Neat sight. It is extremely hot in GF fyi. Nothing rushed through it, it was a constant flow.
Nice explanation 💖💖
Thank you very much
Best explanation
Excellent
Wonderful. Can you now detail the way solar particle forcing affects the Jetstream?
The Super to the super the best to the best. Thanks More. It means you are the world's best climatic organization.
A good scientific explanation
Amazing🔥🔥🔥
This video is so understandable!!!!Damn!!!!
Best video
Thank you
*This is amazing, but probably too complex for me to worry about.*
Best explaination
Awesome.....great ....
A very good explaition.
I am taking a class right now and this is why I am on this cite.
Do a video on the quasibienneial
good video
Can you do a piece on the Magnetosphere and how it holds our Jet streams in place?.
Great !
great video but what about subtropical jets
Here you go:

Guess I'll become a jetstream expert to plan my next holidays.
thanks

How is the exact path/shape and position of the jet stream calculated on a day to day basis? Just from pressure measurements and satellite imagery?
I like this
thanks...
Does the movement of the magnetic field effect the jet stream ? It seams like as the pole moves the proton induction is creating a barrier and pushing the jet stream .
magnificent 👌👌👌👌
Damn this video really broke my memories
A very good audio visual tool, explaining how the whole system works. The voiceover lets it down. Badly read, flat delivery. Better inflexion and more enthusiasm needed. I would also recommend that the soundtrack be removed; it's just distracting from the delivery as a whole. We need more clips on these topics, with the improvements suggested above.
Good
It’s hard to imagine that Mars was once like earth before it lost its magnetic field. Maybe earth is destined to end up like Mars. Maybe all the planets started like earth and ended up a mess and inhabitable over time. Maybe all of the elements have gone into space and accumulated into what we call the planets?
No....
climbing both air columns to the same height would make a lower air pressure for the warm column and a higher one for the cold air column...would it not?
that's what I thought :/
Both columns, being of different densities, have different(higher for cold one) rates of decrease in pressure as we go up. At the surface cold one has a higher pressure than hot one but as we start to climb the cold column's pressure decreases faster than the hot one and a time will come when cold column's pressure becomes less than that of hot one. Also you can see it this way - both columns have the same pressure at tropopause but at different heights! Lets say cold one has tropopause at height 8 km and hot one at 10 km. When we climb 8km in both columns we would see cold column has reached tropopause pressure but hot one has to lower it's pressure for 2 more kms to match that of what cold column currently has, at 8 km.
You forgot that the pressure *decreases* as we move upward. So at the same height there will be low pressure for cold air and a higher pressure for warm air
Nope
Yes it would you are correct there
God bless you
what happens when we get an Azores high?
The Jet Streams exist because the Coriolis Effect formula is:
Acceleration (West--->East) = f (Velocity Equator--->Pole, Latitude)
and that has "Velocity" on the right but it has "Acceleration" on the left, which makes it highly-geometrically increasing.
Thanks brother
are jet streams prevailing winds?
Why did u guys delet ur previous jet stream video
It still exists
lovely video. cute.
Got here after learning what happened to texas.
Good video, but does the same theory apply for the subtropical jets?
The Subtropical Jet Stream flows opposite to the Polar Jets. It flows East to West
The cause of the subtropical jets, which flow west to east is slightly different, although, it also involves Coriolis force. Explained in this video:

Track IDs anyone? Bangin
After this brilliant explanation, I would be happy to understand what climate change has to do with jet streams. After all, every cold wave or heat wave caused by a particular stream pattern is assigned to climate change. Is it true that the wiggles are larger now than 20 years ago? I remember flights across atlantic, where pilots used the jet stream to save fuel. These were almost straight lines 20 years ago!
A warmer arctic temperature causes wild swings in jet streams. These swings push the jet streams further south, which actually results in colder winters in areas like the US. That's why I laughed when the conservatives where claiming how global warming can be real when it's so cold outside. Because of the greenhouse effect, the summers will melt the colder winters, and flooding will start to become more natural around the world. Sadly this is already happening.
@@kv3858 Makes sense - partly. But the large swings in the jet streams also increase the thermal exchange between north and south, thus reducing the temp gradient. So its a chicken and egg question. You say, global warming comes first. Thats exactly why I would favour to study the transition period instead of making assumptions.
Isn’t warm air expands and decreases the air pressure? I’m confused.
Yes Warner air expands decreasing air pressure,cold air compresses increasing air pressure
