Document Summary
You need at the very least an 80% to get an a in this class. Ekman flow (wind driven currents) = limited to the ekman layer (top 100 meters of the ocean) and occurs due to wind friction and the coriolis effect. Currents are deflected at about a 45-degree angle at the surface and going down the water column the angle becomes larger. The current strength weakens going down the column. Energy from the equator is redistributed to other latitudes through winds that then cause currents (transport of heat from low to high latitudes). Winds blow from west to east in the nh, but they blow from east to west in the sh. Therefore, cities located near the ocean on the east coast experience warmer temperatures (they are more influenced by the ocean) than cities at the same latitude near the ocean on the west coast in the sh.
