-HADLEY cell circulates air between topics and subtropics (approximates real world well). Warm air rises at the equator-As the flow moves poleward, it begins to cool and sinks at 20Â°-35Â° latitude.-Trade winds meet at the equator, in a region with a weak pressure gradient, called the doldrums.-FERREL cell circulates air in the middle latitudes. -Circulation (at 60Â°-90Â°) within a POLAR cell produces polar easterlies, or surface flows that move toward the equator.Trade winds meet at the equator, in a region with a weak pressure gradient, called the doldrums. -FERREL cell circulates air in the middle latitudes. -Circulation (at 60Â°-90Â°) within a POLAR cell produces polar easterlies, or surface flows that move toward the equator.
Cold heavy air flows south from the north pole and is bent west, forming the polar easterlies. Warm air rises at the equator drawing air from the north which bends to the west, contributing to the trade winds. The Coriolis effect bends the westerlies and trade winds slightly clockwise in the northern hemisphere. Hot air rises at the doldrums. As it rises, it cools producing thunderstorms. The dry air flows north at a high altitude and descends at the horse latitudes and flows back to the equator with the trade winds. This is called the Hadley cell.
