Highly visual, very pedagogic. Excellent.

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

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

oddly easy to understand. good job.

I love this video thanks for sharing it. :)

Brilliant, thank you!

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!

Watching purely out of curiosity and worldbuilding. Very informative

good luck with gcses tomorrow

Fascinating great video

Love these videos!

So much easier to understand now

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

Very good explanation. Thanks

thank you so much!

ok... i love you? Very informative and straight to the point.

how about the trade winds?

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

Thank you

Thank u for the tutorial

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

Masterpiece

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 🙂

Hi, this is quite late on but here I go. Taken from a document I wrote on meteorology because I love it ;) As the earth is a sphere, the equator is going to always be closest to the sun, meaning it takes a shorter amount for a time the UV rays to be absorbed than somewhere on a higher latitude. That’s basically why the poles are very cold and why equator is very hot. At the equator, lots of UV rays are absorbed into the ground. This heats up the surrounding air and water. As the air is very hot, it will rise because it is less dense than the surrounding air. As the air is rising, the temperature will decreases because the air is thinner (the air can hold less heat); once the air temperature reaches the dewpoint temperature, the temperature at which water vapour condenses, the air will condense and forms clouds. The tiny water droplets, inside the clouds, are suspended in the air because they have clung onto small particles of dust or dirt, which is why clouds are visible. (The dirt is NOT why some clouds are darker, that’s because the cloud is denser so less sunlight can pass through it). Once the cloud becomes supersaturated (can’t hold any more water), precipitation falls as rain. As there is so much energy, most of these clouds are cumulonimbus types, which produce immense amounts of rainfall and thunderstorms. Plus, this is why the humidity is so high because there is so much moisture in the air. This cycle will continue creating a semi-permeable area of low pressure at the equator, which forms a tropical climate. Once the air has lost its moisture it is pulled to a lower density area, which is the poles. This air then instead of being pulled along, starts to sink. This sinking air creates a semi-permeable area of high pressure around 30°N. And the first cell. The distance between the equator and 30°N is roughly the size of the Hadley cell. Remember all the cells are mirrored on the southern hemisphere so another area of high pressure would be created at 30°S as well as a second Hadley cell.

@@Jet2Guy I know this was posted a long time ago but I'm trying to find out what drives the lattitude of the high pressure areas for a worldbuilding project. Specifically, I'm looking to find out how atmospheric density and gravity would effect the lattitude of the high pressures (rotation too). If you are able to answer or point me in the right direction I would be very grateful, thanks

Can anyone help me answer this? I cant find it anywhere. Global Wind Oscillation describes a. the sea surface temperature anomalies near the west coast of South America. b. whether the winds are net easterly or net westerly. c. the sea surface temperature anomalies near the west coast of North America. d. how strong the Icelandic low and Azores high are. e. a region of thunderstorms circumnavigating the Earth in the tropics.

Explains it wayyyy better than the faa

pov u have to watch this for online school :(

The color of the Ferrel cells is incorrect. Hot (red) air rises at 60 degrees latitude (along with the polar cell), moves towards 30 degrees latitude while it cools down, and is (should be) cool (blue) when it falls.

1:08 i've never heard someone speak of weather being "contained" before

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?

When you look at a temperature map of Africa, the Sahara desert is warmer in averaged than the tropical rainforest. Should't the Hadley cell be in the opposite direction in Africa ?

Agreed

I am confused. I thought air moves from high to low pressure. Why are the areas where air is descending the high pressure zones?

@vandanahegde9221

5 жыл бұрын

Think of it this way - low pressure areas are those that are the warmest. Air heats up and rises, creating an area of low pressure. So low pressure - air is always ascending. Now, think of the opposite. Areas where temperatures are cooler, have descending air. Air cools down and sinks to the surface. So cool temperatures - descending air - high pressure. Hope that helps!

High/low pressure zones refer to the pressure at the surface. So the pressure at the surface where the air descends (about 30 degrees from the poles) is higher than the pressure at the surface at the equator.

@sebs9511

Warm air has upward bulged isobars, which means that the air pressure in a column of warm air decreases slowly vertically, in comparison with a column of cold air, where air pressure decreases fast in the vertical (compressed isobars). Therefore, above warm air (the Equator for ex) forms an area of higher pressure, compared to the pressure above colder air (30*-40* latitude for example). So yes, air moves from high to low pressure, but this time at higher levels. (The opposite airflow forms over the surface due to obvious reasons)

i don't get why the hotter, less dense air is the one to move to a high pressure zone instead of the opposite, could someone shine a light here?

Upper ferrel cell winds dont go north to south. This is proved to be wrong. Because of the troposhpere is descending equator to north air cant go up. This is impossible. All upper winds go equator to poles
