WebSep 27, 2024 · The currents descend back toward the ground at about 30° north latitude. As the current descends, it gradually moves from the northeast to the southwest, back toward the Equator. The consistently circulating patterns of these air masses are known as trade winds. Impact on Human Activity WebConvection The movement of warm and cool air creates a convection current. Birds, like this soaring bald eagle, use convection currents to rise and fall with very little effort. So do gliders which are aeroplanes without engines. An aeroplane tows a glider up into the sky.
