Kõrgrõhuperioodide

Kõrgrõhuperioodid, often referred to as high-pressure periods or anticyclones, are significant meteorological phenomena characterized by atmospheric pressure above the surrounding areas. Within a high-pressure system, air tends to sink, which inhibits cloud formation and leads to generally stable and fair weather conditions. This sinking motion warms the air adiabatically, further reducing the likelihood of precipitation.

During a kõrgrõhuperiood, winds typically circulate in a clockwise direction in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere, moving away from the center of high pressure. These periods can vary greatly in duration, from a few days to several weeks. Their presence is often associated with settled weather, clear skies, and moderate temperatures, although in winter they can bring very cold and dry conditions due to the lack of cloud cover to trap heat. Conversely, in summer, they can lead to heatwaves. The persistence of these systems can influence regional weather patterns for extended durations.
