However, the direction and speed of water currents do not match those of the wind currents above them. A 20 km/h eastward wind does not produce a 20 km/h eastward current. Ocean currents are much slower than winds due to friction. phoaming edison

"WebThermohaline circulation (properly described as meridional overturning circulation) of the world's oceans involves the flow of warm surface waters from the southern hemisphere into the North Atlantic. Water flowing northward becomes modified through evaporation and mixing with other water masses, leading to increased salinity. " - How do thermohaline currents form

Are there currents in the deep ocean? Deep ocean currents are driven by density and temperature gradients. This thermohaline circulation is also known as the ocean’s conveyor belt.

WebApr 5, 2024 · Ocean currents are moved by winds, thermohaline circulation, tides, and differences in the water density. The wind creates waves on the surface which pushes the water in a certain direction. Thermohaline circulation is the movement of deep, cold, and dense water from the ocean depths to the surface. ...
