Atmosferyk Pressure: Thee Enginee of Weathers

Systemy high-Pressure (antycykliny)

In high--pressure systems, air descends from the upper atmosfere toward thee Earth 's surface. As this air sinks, it compresses and gear adiabaatically (with out heat exchange), which sich hammes cloud formation by reducing relative humidity. This sinking motion leads to stable atspresh conditions and generally fair weathe.
