In meteorology, a cyclone is an area of low atmospheric pressure characterised by inward spiraling winds that rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere of the Earth.[1][2] Since the generic term covers a wide variety of meteorological phenomena, such as tropical cyclones, extratropical cyclones, and tornadoes, meteorologists rarely use it without additional qualification.
