What is global circulation? | Part Two | The three cells

Global circulation on our rotating Earth splits the atmosphere into three cells in each hemisphere: the Hadley cell, Ferrel cell and Polar cell. In this video, we look at how air moves around each cell and how this controls the location of the world’s deserts and rainforests.

I'm in an ecology class and these videos are insanely helpful, thank you!

Highly visual, very pedagogic. Excellent.

Watching purely out of curiosity and worldbuilding. Very informative

Really helped with my revision for mocks. Clear explanations and diagrams helped me understand the concept well. Thank you!

The animation and background music remind me of Mario Galaxy

there is no "purpose" in physics. it just behaves according to the laws of physics.

besides that minor point, amazingly concise and in-depth explanation!

Hadley cell- is the largest cell and the warmer less dense air rises and contains all of the weather

Polar cells- if air leaces the polar cells it starts to warm and rise. They are the smallest cells

Ferrell cells- in the opposite direction and is not a weather cell, it gives us our regions

Fantastic video. It helped me much more than my set coursebook on the subject. Simple and clear, with easy to follow illustrations.

Best vid by far!
(Artifecian says of things that are a little different.)

It's so simple but very explanatory

[madenaarcher]

I like the animation and explanation. This was so simple and key information. You

I missed this video in class cause the music made me fall asleep, happened again rewatching it at home XD

Love your accent...it makes me remember stuff because of how l mimic you when you talk

0:22 Why would we get a single cell in each hemisphere? If the earth was tidally locked, wouldn't we get many cells that point towards the "sun-pole" from every angle?

[Dinatem]

ok... i love you?

Very informative and straight to the point.

[taewtoyingtrakoon]

I love this video thanks for sharing it. :)

[milesgumbus]

Explains it wayyyy better than the faa

[teddybear-gk]

Thanks for the great explanation. One question: If earth rotates much faster, there would be another cell? Like 4 cells on northern hemisphere?

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 Know 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 cells instead of 2 or 4 ?
Thank you very much .
Hope you understood my question 🙂

Thank you very much! So well done and easy to understand.
