High Pressure System

A high pressure system, also known as an anticyclone, is an area in the atmosphere characterized by relatively higher atmospheric pressure compared to the surrounding areas. It is typically associated with fair weather conditions. In a high pressure system, air descends and diverges outward, leading to the suppression of cloud formation and precipitation. As the air descends, it warms, leading to clear skies and generally stable atmospheric conditions. High pressure systems are often associated with calm winds, cool temperatures, and lower levels of humidity. They can persist for days or even weeks, influencing weather patterns over a large region. On weather maps, high pressure systems are often represented by a large “H” symbol.
