Аннотация: An upwelling is a rise of deep sea waters to the surface. A minimum of four types of upwelling have been identified: (1) coastal upwelling; (2) large-scale wind-induced upwelling in the open ocean; (3) upwelling related to tropical cyclones; and (4) upwelling related to topography. The primary zones of upwelling are located off the eastern boundaries of oceans. A downwelling is a process in the opposite direction. Basic areas of downwelling include the coastal waters of Antarctica (basically, the Weddell Sea) and the North Atlantic (predominately off the Greenland coast). The area of downwelling zones in the world’s oceans is much smaller than that of upwelling zones, as the downwelling rates are always 2–3 times larger than upwelling rates. Upwelling and downwelling are of importance for two kinds of human activity: (1) fisheries and (2) recreational activities. In addition, they play major ecological and climate-forcing roles.
