Atmospheric circulation refers to the large-scale movement of air in the Earth's atmosphere, driven by the uneven heating of the planet's surface by the Sun. This process creates wind patterns and influences weather systems. Warm air rises near the equator, while cooler air sinks at higher latitudes, leading to the formation of distinct circulation cells, such as the Hadley Cell, Ferrel Cell, and Polar Cell. These circulation patterns play a crucial role in distributing heat and moisture around the globe. They help regulate climate and weather, affecting everything from tropical storms to desert formation. Understanding atmospheric circulation is essential for predicting weather and climate changes.
