A cyclone and its counterpart, an anticyclone is a large-scale system of air circulation in the atmosphere in the zones between the equator and either of the poles. A cyclone is a storm or system of winds that rotates around a center of low atmospheric pressure. An anticyclone is a system of winds that rotates around a center of high atmospheric pressure. In a cyclone the central air pressure is lower than that of the surrounding environment, and the flow of circulation is clockwise in the Southern Hemisphere and anticlockwise in the Northern Hemisphere. An anticyclone system has characteristics opposite to that of a cyclone. That is, an anticyclone's central air pressure is higher than that of its surroundings, and the airflow is anticlockwise in the Southern Hemisphere and clockwise in the Northern Hemisphere. |
