- 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 is very well done.
Thanks for this information! My memories were really broken.
God bless this video being accurate, until now the truth went unspoken!
Jetstream sam is a brazilian who can double jump
Monsoon is an emo who ate the chop chop devil fruit
@@RedNumber19hello
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
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
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
This just saved me from failing my Meteorology final! Thank you Met Office!
Did you pass it?
Chris Johnson I did!!!
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.
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.
Wonderfully lucid explanation of something that had been a mystery to me. Many thanks!
Jetstream sam
This is the best jet stream explaniation in the whole CZcams, thank u so much!
Perfect level of explanation and excellent visual demonstration, thank you for the video 👌
Extremely useful, accurate explanation !!!!! THANKS A LOT....
Excellent explanatoin of complex subject: THANKS!!
This video is excellent. This is exactly what I wanted to learn.
Very informative and I learnt a lot from it.
Excellent explanation, very well done! Thank you!
Very informative, thanks.
Great explanation. Thank you.
Extremely good. thanks!
Wow. Very well explained. British have the best Met Office.
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.
Clear explanation with animation. Thank you.
Wow. Just amazing. You Never disappoint.
great video, good explanation. Thank you!
It was a great explanation thanks a lot.
I always wanted a good explanation. Thank you
Probably the best video ive watched on jet stream
superbly explained..... thanx a lot
Well spoken and easy to understand video.
Ohhhh lovely explanation...so many doubts cleared in single video..Thank you so so much..❤❤
Fantastic explanation I think the best one I found on the web
Every child should learn this, it is amazing to see the Earth's motion and winds in action. Great video. Thank you.
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
Awesome explanation...!!!
Good thing about the video was covering all the causes and effects.
excellent! thank you
Powerful Explanation
Great explanation, thanks so much
Thanks teacher
it helped me a lot to understand jet stream
Thank you❤️
From Sri Lanka 🇱🇰😍
Really helpful . Much easier for a layman to understand .
Mam, you cleared my doubt. Thank you !
Fantastic explanation. Thank you very much indeed. I will now be able to hypnotise people with this knowledge.
Very interesting. I learned a lot. I'm studying for the Airline Transport Pilot knowledge test (US FAA), so this was very helpful.
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.
Thank you very much
Wonderful. Can you now detail the way solar particle forcing affects the Jetstream?
Best explanation
Superb...😁😁 Explained
Nice well explain
Nice explanation 💖💖
sam
Excellent
*This is amazing, but probably too complex for me to worry about.*
This video is so understandable!!!!Damn!!!!
Thank you
A good scientific explanation
The Super to the super the best to the best. Thanks More. It means you are the world's best climatic organization.
Awesome.....great ....
Amazing🔥🔥🔥
A very good explaition.
Best explaination
Best video
Great Video! 👷
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
I am taking a class right now and this is why I am on this cite.
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?
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 .
I still feel like I can't understand 😔
great video but what about subtropical jets
Here you go:

Can you do a piece on the Magnetosphere and how it holds our Jet streams in place?.
Great !
thanks
Guess I'll become a jetstream expert to plan my next holidays.
Thxs
Damn this video really broke my memories
I like this
good video
thanks...
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.
magnificent 👌👌👌👌
Do a video on the quasibienneial
Good
what happens when we get an Azores high?
God bless you
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....
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
Got here after learning what happened to texas.
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.
are jet streams prevailing winds?
Very well explained video but impossible to concentrate with the soundtrack. If budget would allow I'd suggests getting a pro VO done but htis one would be fine wothout the music.
Stop complaining and be thankful
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:

Oh boy do I respect you weather guy...
How did you know that at a given height, warm air column will have more pressure?
because the cold air column looses pressure more quickly to hight than the warm air colum as the cold air column is more densely packed
Hemanth Addala Pressure is because of the weight of the gases above the given height, and will depend on the (height left below tropopause upto that point)*(air density) and not just air density, although warm air is lighter, the tropopause is higher there ...
Wanna know the answer too
@@ishan_r I think one of the assumption isn't made clear, that is not just two columns share no pressure difference at tropopause, the ground surface pressure are at the same level. We could just say that the pressure level at the tropopause is 30 and the ground air pressure are both 60 for both.The total change/decrease of pressure from bottom to troposphere is the same.For cold air column, from bottom to top, the air pressure just decreases faster, more rapidly than the warm one.
@@ao7594thank you, but how can we say that the pressure for hot and cold air is the same at the surface? It seems like cold air would have a higher surface temperature due to the higher density
