Everything Else . Basically, wind is created by temperature differences caused by the sun's heat.
Wind is any motion of the atmosphere relative to the surface of the earth.
Since the volume of the atmosphere remains about the same, any movement of air in one direction must be offset by a return current. All such movements are essentially powered by thermal convection because of the heat of the sun. For example, the sun warms the spherical earth more at the equator than at the poles, explained Edward O'Lenic, a research meteorologist in the prediction branch of the climate analysis center of the National Weather Service. This uneven warming creates a temperature difference, or gradient. As the warm tropical air rises, the cold air from the poles moves toward the equator to replace it.
