What is high pressure system

A high pressure system is a region of the atmosphere where air pressure is higher than the surrounding areas. This typically results in fair weather conditions, with clear skies and light winds. High pressure systems are associated with descending air that is stable and tends to suppress the formation of clouds and precipitation. They are commonly referred to as anticyclones and are often characterized by their clockwise rotation in the Northern Hemisphere and counterclockwise rotation in the Southern Hemisphere.
