anticyclone
An anticyclone, also called a high, is an area of high pressure where air is subsiding, causing dry weather. Winds are normally light and the weather is settled. Major high-pressure regions are found in the horse latitudes, about 20° to 30° north and south of the equator. There are also large anticyclones in the Arctic and Antarctic. An anticyclone is characterized by clockwise wind movement in the northern hemisphere and anticlockwise movement in the southern hemisphere. See also cyclone.
