Flexi Says: Global winds are the prevailing, or usual, winds at a given latitude. The winds move air masses, which causes weather. The direction of prevailing winds determines which type of air mass usually moves over an area. For example, a west wind might bring warm moist air from over an ocean. An east wind might bring cold dry air from over a mountain range. Which wind prevails has a big effect on the climate. Surface currents are caused mainly by winds but not daily winds. Surface currents are caused by the major wind belts. These winds blow in the same direction all the time. So they can keep water moving in the same direction. Surface currents are created by three things: global wind pattern, the rotation of the Earth, the shape of the ocean basins.
