Anticyclone. An anticyclone is a region of high atmospheric pressure relative to the surrounding air, generally thousands of kilometres in diameter and also known as a high or high-pressure system.Anticyclones appear on weather charts as a series of concentric, widely spaced isobars of 1000 mbs and above.nticyclone.

Anticyclones (commonly known as highs) are predictors of fair weather. Winds in a cyclone blow counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Winds in an anticyclone blow just the opposite. Vertical air movements are associated with both cyclones and anticyclones.nticyclones (commonly known as highs) are predictors of fair weather.
