Thermohaline circulation occurs because winds move warm surface waters from the equator towards the poles, where the water cools and increases in density. Warm surface currents invariably flow from the tropics to the higher latitudes, driven mainly by atmospheric winds, as well as the earth's rotation. Other (more local) causes are the lunar tides and river/ice-melt flow from the land. professor melissa murray.
