The Hadley cell is a large-scale atmospheric circulation pattern that occurs between the equator and approximately 30 degrees latitude in both hemispheres. In this cell, warm air rises at the equator, creating a low-pressure system. As the air rises, it cools and condenses, forming clouds and precipitation. This process releases heat into the atmosphere, which drives the circulation of air within the cell.
As the air reaches the top of the troposphere, it moves towards the poles and begins to descend around 30 degrees latitude. This descending air creates a high-pressure system, leading to clear skies and dry conditions in regions such as the Sahara Desert and the American Southwest. The air then flows back towards the equator at the surface, completing the Hadley cell circulation.
Farrell's cell is a mid-latitude atmospheric circulation pattern that occurs between approximately 30 and 60 degrees latitude in both hemispheres. In this cell, air from the Hadley cell and polar cell converges and rises, creating a low-pressure system. This rising air leads to the formation of mid-latitude cyclones, which are responsible for much of the weather in regions such as the United States and Europe.
As the air rises in Farrell's cell, it cools and condenses, leading to cloud formation and precipitation. The air then moves towards the poles and descends around 60 degrees latitude, creating a high-pressure system. This descending air leads to clear skies and dry conditions in regions such as the Mediterranean and the Middle East.
The polar cell is a smaller atmospheric circulation pattern that occurs between approximately 60 degrees latitude and the poles in both hemispheres. In this cell, cold air descends at the poles, creating a high-pressure system. This cold, dense air then flows towards the equator at the surface, where it meets warmer air from Farrell's cell and rises, creating a low-pressure system.
As the air rises in the polar cell, it cools and condenses, leading to cloud formation and precipitation. The air then moves towards the poles and descends, completing the circulation of the polar cell. This descending air creates clear skies and dry conditions in polar regions such as Antarctica and the Arctic.
Overall, the patterns of air movement and associated weather within the Hadley cell, Farrell's cell, and polar cell are driven by the unequal heating of the Earth's surface and the rotation of the planet. These circulation patterns play a crucial role in shaping the climate and weather patterns around the world.

Hadley Cell
- Pattern of Air Movement: Warm air rises at the equator, flows poleward, cools, and sinks around 30° latitude (subtropical high-pressure belt).
- Associated Weather: Tropical rainforests near the equator, deserts and arid regions around 30° latitude (trade winds, monsoons)
Ferrell Cell
- Pattern of Air Movement: Air rises around 30° latitude, flows poleward, cools, and sinks around 60° latitude (subpolar low-pressure belt).
- Associated Weather: Temperate climates, with variable weather systems (cyclones, anticyclones)
Polar Cell
- Pattern of Air Movement: Cold air sinks at the poles, flows equatorward, warms and rises around 60° latitude (polar front).
- Associated Weather: Polar air masses, cold and dry polar climates, Arctic and Antarctic ice caps
