trade winds  

Definition

  • The trade winds are a large-scale component of Earth circulation, occupying most of the tropics, straddling the equator between approximately latitude 30 degrees N and latitude 30 degrees S, with a seasonal shift of the entire trade wind belt system about 5 degrees of latitude northward during summer (July) and southward during winter (December). In the Northern Hemisphere, warm equatorial air rises and flows north toward the pole, the Coriolis effect (caused by the Earth's rotation) deflects the current, and as the air cools, it descends, blowing southwestward from the northeast.
