An area of a pressure maximum relative to its surroundings. A high pressure system has diverging winds which rotate clockwise in the Northern Hemisphere. Also known as an 'Anticyclone'.

The center of an area of high atmospheric pressure. See anticyclone.

An area in the atmosphere that has high pressure and winds that move away from each other into different directions.

An area with greater relative pressure. A barometer in this area would measure the atmosphere as being heavy.

An area of high pressure around which the wind blows clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere. Also called a High.

An atmospheric circulation where the central air pressure is higher than in surrounding areas with an anticlockwise circulation of winds in the southern hemisphere. Highs are generally associated with lighter winds and dry conditions.

An area of relative pressure maximum that has diverging winds and a rotation opposite to the earth's rotation. This is clockwise the in Northern Hemisphere and counterclockwise in the Southern Hemisphere. It is the opposite of an area of low pressure or a cyclone. Related term: anticyclone
