Cyclonic rotation

Cyclonic rotation or circulation is movement in the same direction as the Earth's rotation, as opposed to anticyclonic rotation. The Coriolis effect causes cyclonic rotation to be in a counterclockwise direction in the northern hemisphere, and clockwise in the southern hemisphere.[1] A closed area of winds rotating cyclonically is known as a cyclone.
