A diagram of the general circulation of the atmosphere with marked Hadley circulation between equatorial and subtropical regions, medium-width cells and polar cells

Polar Cell - an air circulation system that occurs on both hemispheres between polar circles and poles, an element of general atmospheric circulation.

The characteristic feature of the polar regions is the very strong cooling of the substrate, and thus the low air temperatures resulting from the small supply of solar radiation. This causes the air to settle above the poles and create high pressure systems there. Air from the heels moves in the lower troposphere to moderate latitudes, where cyclonic systems dominate. There also air due to dynamic convection associated with cyclonic circulation rises up. In the upper troposphere part of the air flows back towards the poles, closing the system.

Winds blowing from poles carry cool air to moderate widths. As a result of Coriolis forces, the wind at the Earth's surface has an eastern direction.
