Answer:
Large global wind systems are created by the uneven heating of the Earth's surface. Warm air rises at the equator and moves toward the poles. ... At the poles, the cooler air sinks and moves back toward the equator. All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion. Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds
