A Wind generated current is a flow in a body of water that is generated by wind friction on its surface. Wind can generate surface currents on water bodies of any size. The depth and strength of the current depend on the wind strength and duration, and on friction and viscosity losses, [1] but are limited to about 400 m depth by the mechanism, and to lesser depths where the water is shallower.

Knowledge of surface ocean currents is essential in reducing costs of shipping, since traveling with them reduces fuel costs. In the wind powered sailing-ship era, knowledge of wind patterns and ocean currents was even more essential. Using ocean currents to help their ships into harbor and using currents such as the gulf stream to get back ...
Also, the wind stress can be described as the flux of horizontal momentum applied by the wind on the water surface. The wind stress causes a deformation of the water body whereby wind waves are generated. Also, the wind stress drives ocean currents and is therefore an important driver of the large-scale ocean circulation. [1]
A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster ...
A crucial system of ocean currents may already be on course to collapse with devastating implications for sea level rise global ... The AMOC’s collapse could also cause sea levels to surge by ...
However, wind and tides cause mixing between these water layers, with diapycnal mixing caused by tidal currents being one example. [14] This mixing is what enables the convection between ocean layers, and thus, deep water currents. [1] In the 1920s, Sandström's framework was expanded by accounting for the role of salinity in ocean layer ...
Impacts on the N.C. coast can include changes in sea level and wind speeds. The shift appears to coincide with recent reports of hundreds of cold-stunned sea turtles washing up on North Carolina ...
Flotsam can be blown by the wind, or follow the flow of ocean currents, often ending up in the middle of oceanic gyres where currents are weakest. Within garbage patches, the waste is not compact, and although most of it is near the surface of the ocean, it can be found up to more than 30 metres (100 ft) deep in the water. [69]
