Surface ocean currents
Surface currents are driven by the winds, and in turn influence atmospheric circulation. Both are shaped by the spin of the Earth. Surface currents form huge gyres — circular patterns that, because of the Earth’s rotation, flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere. Boundary currents, on the edges of the gyres, carry warm tropical water to the higher latitudes and cold polar water to the lower latitudes.
