Winds blowing spirally outward from centers of high pressure are known as anti-cyclones. They are just the reverse of cyclones. Their movement is clockwise in the Northern Hemisphere and anti clockwise direction in Southern Hemisphere. They are more common in the subtropical high pressure belts and absent in the equatorial belt. They are circular in shape, larger in size and extent and their track is highly variable. The weather is generally associated with anticyclones is find and dry.
The anticyclones are divided into two groups such as permanent and temporary anticyclones. Permanent anti-cyclones are mainly centre in the temperate regions where the meeting of tropical and temperate air mass takes place. In between the two temperate cyclones there will be anti-cyclones. In the interior of continents the high pressure centers are developed during the winter season. It is due to lower amount of temperature
