polar cell

A polar cell is a part of Earth's atmospheric circulation near the poles, where cold air sinks and spreads outward at the surface, creating high-pressure zones. This air then flows toward lower latitudes, warming and rising around 60 degrees north and south, forming the boundary between polar and ferrel cells. These cells help regulate global climate by moving cold polar air toward the equator and balanced warm air toward the poles, driving weather patterns such as polar easterlies and influencing storm systems.
