Kõrgrõhuperiood

Kõrgrõhuperiood, also known as an anticyclone, is a weather phenomenon characterized by an area of high atmospheric pressure. In a high-pressure system, air sinks from higher altitudes towards the Earth's surface. As this air descends, it warms and dries, which typically leads to stable weather conditions.

The sinking air suppresses the formation of clouds, and therefore, high-pressure systems are usually associated with clear skies and calm conditions. Precipitation is infrequent during a kõrgrõhuperiood, and if it occurs, it is generally light. Winds in a high-pressure system tend to be light, circulating clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere around the center of highest pressure.

Kõrgrõhuperioodid can persist for several days or even weeks, influencing regional weather patterns. They can bring periods of sunshine and warmth in summer, or cold and dry weather in winter. The presence of a high-pressure system often prevents the passage of storms or other low-pressure systems, as the descending air acts as a barrier. The size and intensity of a high-pressure system can vary significantly, impacting the extent and duration of its weather effects.
