Understanding Atmospheric Circulation Patterns

[@Nelybeans]

you, sir, have just saved me from a complete mental breakdown. thank you so much, this was very helpful!

[@foldby37]

The best easy understandable explanation i have heard so far, thanks a lot....

[@PaulHBeckwith]

Gerner Larsen Thank you Gerner.

[@ParanormalPat]

Glad to see someone going the old school route and using a chalkboard to teach something. Thanks for this educational upload.

[@yusufalasmi8923]

I loved how raw this video felt, I wish school was this inviting.

[@zack_120]

This lecture is like gold in a box its beauty invisible: too condensed it needs to expand into a quarter long course.

[@woohoo721]

THANK U THANK U THANK U you just saved my grade 🙏🏽 this is like the 10th video I've watched on this and the first one I fully understood

[@swethanaidu7271]

I honestly have gone through 6 different videos on Air Circulation and your video is the first time i actually got it. Thank you for the explaining it so easily and I know for a fact that I will be able to recreate this information from my memory hereafter. Thank you. Have a great day. :)

[@PreachRevolution]

I stopped off at your donation box to show my appreciation. Please keep fighting the good fight with real information!!

[@dilaraduman955]

The way the meterological system of Earth works is perfectly explained. Thank you very much for your efforts Paul.

[@paulcanovas7950]

you're explaining so much better than my teachers,thank you sir

[@leclercj764]

You're the man! Great explanation THANK YOU From: a University of Calgary student with an exam on this next Wednesday

[@pratikp4192]

I am a student pilot & my concept got very clear now which I didn't understand at all in my 3 months meteorology lecture, one of the best teachers I came across...thank you so much sir.

[@sakinalaasraoui5085]

Thanks this effort teacher I'm from Morocco and i understand all about atmosphere circulation 🇲🇦🙏🙏🙏🙏

[@maryanaiseku2220]

Best teacher trophy goes to you from me.....wish you were my instructor... Thanks KZbin now you are.

[@DavidvanDeijk]

very good brief description of Hadley cell and polar cell. metrology basics.

[@chereoge]

You're the man! Great explanation THANK YOU From: a University of Windsor student with an exam this coming Wednesday. Tomorrow.

[@chiefnavigator9088]

Thank you Paul. I understood your explanation and models immediately. You made this so simple.

[@Vbluevital]

Bravo Paul! All most lost a mouth full of coffee at why the sun rising in the east. Now to find the video series, searching to see if you predicted two sets of Hadley. Ever Grateful

[@tobyr3]

Excellent description of the basics Paul.

[@cpetri766]

Thanks Paul, I am going to draw this on a large sheet of paper and then go back to your other videos to fill in more information onto the large paper. I will use a XL artist sketch pad,....appx 30" x 40". I greatly appreciate your educational videos. I'm also donating some money because you spend your free time helping us understand the earth and weather patterns in relation to Abrubt Climate Change.

[@PaulHBeckwith]

cpetri766 Thanks c! Sounds like a great project!

[@k956upg]

I was fascinated then confused towards the last bit & accepting my intelligence is more practical based than IQ measurable theory & numbers processing based I decided I would watch it again tomorrow & another time next week to process the information. People that can digest this in one go I salute you..I guess it's also a subject far from my knowledge base or career & im just learning for the sake of knowledge @ 3 am to fend off an anxiety attack that woke me up so I'm just distracting myself for 20 mins.

[@aditya1642]

Thank you sir. That was the best explanation available on the net.

[@spy8464BB]

Excellent explanation . It is always wonderful when someone can transmit a concept visually . This is my favorite and best way to learn. Very nice job. After you listen to the entire video I urge you to watch it over. I wonder if you will notice that the instructor explains how he will show us with his explanation how abrupt weather changes are creating the current climate change environment . Take note , he doesn't . I'm not attacking the instructor , I think he does a brilliant job. My point is climate change caused by man is a hoax. The climate continues to change and has done so from the begining and will continue to change for the good and the bad.

[@kalpanadaniel7360]

Excellent explanation in very simple terms! Thank you for posting this video.

[@lornarosa8126]

Super helpful video, sir! Very smart guy. I thank you so much for explaining things so clearly!

[@AliciaW09]

wow.. i think i know where my next degree is coming from. this is FASCINATING.

[@prasadkarri3128]

Sir..You clear all my doubts about this topic, thank you so much

[@agnesgisbertkapinga2700]

you are incredible lecture for sure. Thank you for sharing knowledge with us.

[@ArwenTelian]

Thank you so much! I was trying to learn about global atmospheric circulations from a text book, it took me most of a morning, and I still didn't understand.

[@nishantbhavsar536]

Great video, for my Atlp studies

[@carlovonterragon]

Very good explanation, thank you 🙂

[@vladbursa8622]

Easy and understandable explanation

[@amirhi1099]

Very good and clear explanation. Thanks

[@cynthiajose7787]

Good stuff. Please do a comprehensive and descriptive video on, jet stream, ENSO, cyclonic disturbances. Thanks

[@doug5372]

Great video expanded my knowledge!

[@huskyxopowo2605]

Paul, you're awesome.

[@PaulHBeckwith]

Husky Xopowo So are you Husky!

[@DougHanson2769]

He’s so good.

[@jr13763]

Amazing explanation. Glad I’ve found this.

[@anthropoceneclimatechange245]

Paul, Those waves are called Rosby waves! He is a good Atmospheric Physicist but I also should have been one to. I made my mistake decades ago from not considering university due to the fear of college tuition cost. Its a regret I hold in my heart! I really do hate the US goverment for putting milliary budgets over the quality of life of the middle class. At one time, the Federal Goverment used to subsidize college Funding.

[@zbigniewbohdanowicz8897]

This is a great informative video, thank you!

[@kurohikes5857]

I really appreciate this video. if you made a video taking us step-by-step through the mathematics I'd love that. it is helpful for the public to be able to see and understand how this works mathematically. I'd pay to learn the math. I know you are thinking: the public won't get it... but that is wrong. we have the internet and math is now accessible to the public. just show the formulas and and how to solve, perhaps some generalization.

[@PaulHBeckwith]

John Dow Sounds like a good idea. I will do some kick-ass highly technical videos on various topics, for fun and variety:)

[@kurohikes5857]

Paul Beckwith then I will be sure to make a donation.

[@moriartyholmes2981]

This is just the information I'm looking for!

[@cmh-1400]

Thank you, Paul. You explained this perfectly!

[@tristan7216]

Extra credit question: do these convection cycles extract energy from the Earth's rotation, gradually slowing it down, add energy and speed it up, or are they completely neutral, having no effect? I believe rotation is very gradually slowing due to tidal forces, planets and moons close to the larger body tend to become tidally locked even if they have no atmosphere, but what is the effect of the air circulation specifically? Final boss problem: factor in ocean currents also and model the whole system.

[@BantamJJ]

Thank you for producing this video !

[@0limebox0]

So concise!

[@iFrostNight]

Very good video thank you

[@Ausprep]

great work I likes the video very informative.

[@oscarroca2791]

Hey 🙂 First of all, thank very much for your posts and very informative materials. I got a question that it would be amazing if you any link , webside to Know the answer. - How are the hadley, ferrel and polar cells formed? On your videos explain how the air circulates around them and the direction of the winds and jet streams due the Coriolis apparent force but how have these cells been formed and why are there 3 cella instead of 2 or 4 ? Thank you very much . Hope you understood my question 🙂

[@curiousperson575]

Make a vedio on jetstreams and how they can affect weather of a place.

[@frokostjuicen]

Thanks for video. That being said, it should not be named *understanding. Rather bulletpoints or headlines.

[@QMCESAR]

Great explanation.. thanks a lot

[@USYADAV-mt1ql]

Great sirr from india

[@nabimenj641]

Great video. Thank you very much

[@ravenken]

Thanks Paul but why are you only describing only a singular jet stream where there are two jet streams in any diagram I see? Also, it was my understanding that the Polar jet was the strongest but now, b/c of AGW, that polar jet has dissolved since the temp gradient went down to nothing. The weak polar jet has left the Beaufort Gyre free to roam around the northern hemisphere.

[@PaulHBeckwith]

Raven Ken Just to keep it simpler. The two jets in the model are at the borders between the 3 cells, so at 30 and 60. Modified in reality by land/ocean contrasts and topography, etc...

[@nickknight5373]

V.useful stuff, Paul. Would be helpful also if you organized your content into playlists. Anyhow, thanks!

[@julz2017]

So helpful! Thank you!

[@aliarikan6655]

thanx sir .. great work

[@Anagrabi]

Paul I got a question why the air falls exactly at 30° and 60° ??

[@ravenken]

They don't 'exactly' but they do generally. The 'reasons' they fall there USE to be significant temperature gradients would cause that area (i.e. 30 and 60) to be where a 'tipping point' of stability would be reached and cause the drop in air in the creation of the Hadley, Ferrel and Polar cells. With the warming of the atmosphere (especially in the northern latitudes around the arctic) we have lost the temperature gradients and now we do not have a circumpolar jet stream like we use to have but now a wavey trough of air that has little to no stability. Dr. Jennifer Francis is one of the leading experts on the jet stream. Check out one of here videos...

[@semanticscribe]

Yeah, I missed that explanation as well...

[@Anagrabi]

Thank you very much!!!

[@PaulHBeckwith]

Grabielita Esco Raven has a great response. The 3 cell model explains things like the ITCZ near the equator, deserts centred near 30 degrees N and S (air descends), and stormy low pressure belts near 60 N and S (air rises there). Not a perfect model, but decent for many things...

[@Varnita29]

Really helpful... Thank you! :)

[@MOHITYADAV-fj4zp]

Fabulous sir

[@thebobby131982]

Mr. Beckwith, thank you for the lecture, it was certainly very educational. I am learning about the circulation pattern at the moment, and I have a question where you drew the "jet stream" and called it such. All of the surface arrows you've drawn I understand are the surface wind patterns. Where you drew the "jet stream", seems to correspond to the westerlies at about 40 degrees which I also understand are generally surface winds. I understand the term "jet stream" to be those high near the the limits of the troposphere. Are you calling the westerlies the jet stream, or did you in fact mean the jet stream at high altitudes but just happened to draw it where the westerlies are? Perhaps there are some holes in my understanding, but I do hope that you could clarify this for me. Thanks so much.

[@joeymoon7843]

At the Fennel cell why does the air descend at the 30th parallel (hotter) and rise at the 60th parallel (colder) and why are there only three cells per hemisphere? Thank you

[@babafareed6794]

Could you explain please at 60 degree latitude why air turns towards poles when it is high pressure there and low pressure at 60...???

[@steenmortensen6410]

thank you..(i `m searching what military bombs in the ionosphere affects the climate

[@sidharthpatel7380]

Can u gimme something about cause and formation of jet streams.

[@bidyakarak3117]

Dear Paul, Thans for uploadig this beautiful lecture. Is the jet stream that is moving from west to east in between 30 to 60 deg called Rossby wave? Could you please identify the Rossy wave in this picture?

[@manishaluthra6516]

Sir pls explain why tropical deserts are located between 20 - 30 degrees latitude?

[@deepikasinghchauhan8784]

Thanks a lot sir ☺

[@paulreimer9358]

And how right you were!

[@svlonestar7645]

Double liked 👍👍

[@bla156]

Either I missed it or didn't get basic answer. What is the explanation for having cell border at 30 degrees? It was just drawn like that without any comment...

[@johnny970]

So my question is as the ball heats up ? Where would the best weather be on that ball for the duration of our lives here? Oh...and that jacket suits you well.

[@ajeet.y]

Thanks!

[@shaharajmojhaidul6794]

Sir, plz recommend the reference book

[@kstudy6187]

I didn't get it.. Suppose hypothetically I am sitting at 30° South latitude facing towards the pole and lets apply some simple vector algebra 1)Earth moves West to east right so I will observe air moving East to west right but because earth speed is higher at 30° than 60° south the vector at 30° will be longer than 60° one so (vector at 30° directed towards west - vector at 60° directed towards west ) = Positive vector directed towards west 2)Now winds other movement is towards pole vertically from at 90° agle from 30° to 60° latitude we got two vectors one towards west and one towards 90° south perpendicular to this and the resultant will be towards South-West...And figure at 11:23 shows that direction is towards South-East Can anyone explain me?

[@RandyOm]

I think I understand everything in this video except: why does the circulation South of (or generated from) the 30S latitude flow Westward? And why does the circulation North of (or generated from) the 30N latitude flow Eastward? What confuses me is thinking that these two flows are flowing against the spin of the Earth?

[@steenmortensen6410]

because the angular velocity is faster the more distance from the turning axe. (the same as a Wheel turning..) and then an object moves closer to the centre, will increase the speed.

[@danwylie-sears1134]

Why do we have three cells, rather than two or four? I understand that we can't have just one, because easterly winds over the whole planet would have drag pushing the atmosphere eastward everywhere, until the slowest-easterly winds became westerly. But as far as I know, two or four would be possible.

[@RobinMario]

Why does it "have to move" to he north or the south?

[@leolieb9489]

1hPa = 1mbar isn’t it? great explanation tho

[@billbraskey2759]

hectopascal not hexopascal if Im correct no?

[@alanberry9643]

You didn't explain why the air decides to form a cell at exactly 30 degrees south and north? Why is that? Why doesn't it go all the way to 90 degrees and then go down?

[@abcdef2069]

at 12:08 as my understanding of your explanation is... ideal trade wind occurs only along the equator line by being jammed by southern and northern hemispheres and the trade wind doesn't occur in a wide band everywhere between 30S to 30N. your explanation totally makes sense. but why do other stupid people explain trade wind like a whole wide band phenomenon to confuse the heck out of me. i need one more explanation, you get an easterly trade wind but you also get a westerly equator counter-oceanic flow, so how do i move to the west on ship and not on airballoon?

[@shivanichoudhary9250]

Then where does that deflection wind goes out ??

[@sol303]

So if the globe is spinning 1000 miles per hour at the equator how does this spin not create its own current one current going east to west like smoke if I move forward smoke will create a trail behind me

[@murrayobrien9192]

Maybe because space has no density?

[@marialenkova1642]

how can air rise at 60 latitude if air is not warm to rise?

[@mahimabhardwaj4976]

Too good

[@cynthiairwin2065]

Are we sure the climate is changing via man/woman made climate change? Perhaps not, fluctuations? Yes. If climate changes besides its normal annual seasons, which we know it does, I'd put it down to some kind of orbital "wobble". There's great evidence of this, the equator seems to stay put annually and so does the Arctic and Antarctic Circles. Because of this there is a particular set of circumstances that remain little changed and that is the amount of sunlight received in each of the prior named positions on Earth. In other words, we ain't doing diddly squat to weather patterns. Pollution, yes. That always needs to be worked on. The real way to change the weather is axial tilt fluctuations and/or rotational speed differential.

[@adamisaac4685]

is it people who deny climate collapse that disliked this video?

[@kenamick]

Paul, thanks for this explanation of the wind currents. Planning our sailing trip around tge earth just got a bit easier. Question: the belt of rising air at the equator makes sense, due to the concentration of the sun's rays. Does the position of this belt move northward in the summer and south in the winter? Thanks, Ken at Facebook.com/svsecondwind

[@goodlifetalk8779]

Sir use mic

[@pranaybhagat5807]

Indian teachers are far better. They give explanation of each and everything. Why the winds are moving here and there? They'll explain everything.

[@rchuso]

Statistically.

[@PaulHBeckwith]

Rand Huso Huh?! Statistically, averaging over time there are (or at least Were) two jets (Polar Jet near 60; Subtropical Jet near 30) in each Hemisphere. On a day to day basis; jets are often splitting, fractured, streaky, all over the place...

[@rchuso]

The Hadley cell is a statistical thing. I remember a time when there were clear depictions of the Polar Jet Stream and the Subtropical Jet Stream. In fact, one of my teachers still clung to the "Continuous Polar Front" theory (in '84), and made us draw our fronts accordingly - even when the surface data didn't support it - no change in wind direction or speed, or temperatures, or humidity on either side of the line.
