High-pressure systems are frequently associated with light winds at the surface and subsidence of air from higher portions of the troposphere. Subsidence will generally warm an air mass by adiabatic (compressional) heating. Thus, high pressure typically brings clear skies. Because no clouds are present to reflect sunlight during the day, there is more incoming solar radiation and heating so te… WebMar 22, 2024 · Coastal upwelling is the process by which strong winds blow down the coasts of continents and, in conjunction with the earth’s rotation, cause the surface waters to be pushed offshore. Water from the ocean depths is then pulled up - or upwelled - to the surface to take its place.
