What Is An Ocean Gyre? - WorldAtlas
WebA gyre in oceanography is any large system of rotating ocean currents, particularly those involved with large wind movements. Gyres are caused by the Coriolis effect; planetary vorticity along with horizontal and vertical friction, determine the circulation patterns from the wind curl (). The term gyre can be used to refer to any type of vortex in the air or the sea, … The North Atlantic Gyre of the Atlantic Ocean is one of five great oceanic gyres. It is a circular ocean current, with offshoot eddies and sub-gyres, across the North Atlantic from the Intertropical Convergence Zone (calms or doldrums) to the part south of Iceland, and from the east coasts of North America to the west coasts of Europe and Africa. Web18 de abr. de 2024 · Oceanic motions are multi-scaled, ranging from wind-driven gyre scales set by basin geometry to turbulent mixing scale of a few centimeters. As the energy source supplied by atmosphere is of basin scales, the induced oceanic motion needs to transfer the energy down-scales so that it could be dissipated at mixing scales and a … chum english
