Kõrgrõhkkonnad

Kõrgrõhkkonnad, also known as anticyclones, are large-scale atmospheric systems characterized by high atmospheric pressure at their center. In the Northern Hemisphere, winds in a high-pressure system blow clockwise, while in the Southern Hemisphere, they blow counterclockwise. This is due to the Coriolis effect. High-pressure systems are generally associated with stable weather conditions. As air sinks within a high-pressure system, it warms and dries, inhibiting cloud formation and precipitation. Therefore, days with high-pressure systems overhead are typically clear and sunny with light winds. Temperature variations can be significant, with warm days and cool nights, especially during periods of clear skies. Kõrgrõhkkonnad can persist for several days or even weeks, influencing regional weather patterns. They often form when large air masses cool and become denser, or when atmospheric waves cause air to descend. The movement of high-pressure systems is influenced by the jet stream and other prevailing atmospheric currents. Their presence can lead to periods of drought if they remain stationary for extended periods.
