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.
