Plain English Meaning
Air spinning around an area of low pressure. North of the equator it spins to the left (counterclockwise); south of the equator it spins to the right.
Full Definition
The rotation of air around a low-pressure center. In the Northern Hemisphere this rotation is counterclockwise; in the Southern Hemisphere it is clockwise. The pattern results from the pressure gradient pulling air toward the low while the Coriolis effect deflects that moving air, producing a curved, inward-spiraling flow.
