trade winds
  (trād)   
Winds that blow steadily from east to west and toward the equator over most of the Torrid Zone. The trade winds are caused by hot air rising at the equator, with cool air moving in to take its place from the north and from the south. The winds are deflected westward because of the Earth's west-to-east rotation. Compare antitrades.

Encyclopedia Article for trade winds

trade wind

persistent wind that blows westward and toward the Equator from the subtropical high-pressure belts toward the intertropical convergence zone (ITCZ). It is stronger and more consistent over the oceans than over land and often produces partly cloudy sky conditions, characterized by shallow cumulus clouds, or clear skies that make trade-wind islands popular tourist resorts. Its average speed is about 5 to 6 metres per second (11 to 13 miles per hour) but can increase to speeds of 13 metres per second (30 miles per hour) or more. The trade winds were named by the crews of sailing ships that depended on the winds during westward ocean crossings.
