		+	==Introduction==
		+
		+	Due to the earth’s rotation, the air mass curves relative to the earth’s surface. In the '''Northern Hemisphere''' this effect causes the air to deflect '''to the right''' of the direction of the air movement and in the '''Southern Hemisphere''' the deflection of the air is '''to the left''' of the direction of air movement. This is called the '''Coriolis effect'''.
		+	Because of the rotating earth, a point at the equator moves faster than a point at higher latitude. Both points make one full rotation at the time of one day, but the point at the equator has to travel a longer distance. For this reason, the point at the equator is moving faster. The air moving north or south away from the equator toward the poles moves faster than the earth beneath it and the air curves relative to the earth’s surface. <ref>Karleskint G. 1998.

		+	==Ekman spiral==
		+
		+	The ekman spiral is a consequence of the '''coriolis effect'''. When the surface water moves by the wind, they drag the deeper layers with them. Each layer of water is moved by friction from the shallower layer and each deeper layer moves more slowly than the layer above it. The deflection of the surface current has an angle of '''45°'''. This creates a spiral called the Ekman spiral. At a depth of 100 meters, the water flows in the opposite direction than the surface current. The '''net water transport''' is perpendicular ('''90°''') to the initial wind direction and this is the effective direction of the current flow. <ref>http://en.wikipedia.org/wiki/Ekman_spiral</ref> <ref>Pinet P.R. 1998.Invitation to Oceanography.
