<br>Wind moving over the water also produces a great deal of evaporation leading to a decrease in temperature called evaporative cooling related to latent heat. This warmer fresher water from the Pacific flows up through the South Atlantic to Greenland where it cools off and undergoes evaporative cooling and sinks to the ocean floor providing a continuous thermohaline circulation. 10
