These cold patches are what remains of the subsurface "engine" of the La Nina, now starting to turn off slowly as warmer waters move in. There are two main driving forces for ocean currents; surface wind and the (horizontal) gradients in temperature and salinity.

Natural selection selects for individuals that compete less. a. increased recreational use of Lake Erie Surface ocean warming appears to be speeding up global currents, reconstructed here from satellite and ship readings. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area. Hover over or click on the icons to learn more about these human causes of change and how they influence, or are influenced by, ocean circulation.

How they move influences climate and living conditions for plants and animals, even on land. As we have seen, winds blow from areas of high atmospheric pressure to regions of low atmospheric pressure. Overdraft Thermohaline circulation occurs because winds move warm surface waters from the equator towards the poles, where the water cools and increases in density. b. Some of this water gets so cold that it freezes, leaving its salt behind in the remaining water, further increasing the density of this water. a. amplitude The movement of air masses brings us our daily weather, and long-term patterns in circulation determine regional climate and ecosystems. Water flows in a circular pattern--clockwise in the Northern Hemisphere, and counterclockwise in the Southern Hemisphere. The globally averaged ocean .
