AI overview
Wind is the natural movement of air across a planet's surface, occurring at many different scales—from brief thunderstorm gusts to local breezes lasting hours to large global wind patterns. Winds matter because they're driven by differences in how much solar energy different parts of Earth absorb, making them a fundamental part of how our planet's atmosphere and weather systems work.

The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet, which is called the Coriolis effect. Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail.
