• In both hemispheres, trade-wind belts push currents westward across the tropical latitudes of all three major oceans.

Surface currents are controlled by three factors: air currents, Earth’s rotation, and the location of the continents. Because wind is moving air, wind has kinetic energy. As energy is transferred from the air to the ocean, the water at the ocean’s surface begins to move. The website below shows ocean currents and wind belts. http://www.classzone.com/books/earth_science/terc/content/visualizations/es2401/es2401page01.cfm?chapter_no=visualization Global Wind Belts Global wind belts, such as the trade winds and westerlies, are a major factor affecting the flow of ocean surface water. In both hemispheres, trade-wind belts push currents westward across the tropical latitudes of all three major oceans. Westerlies push ocean currents eastward in the higher latitudes of the Northern and Southern Hemispheres.
