What Is Wind?

Wind happens. You can blame it on the atmosphere’s everlasting battle to find balance. As air flows from an area of high pressure to one of low pressure, it creates wind.

Learn all about the massive movement of air, its highest recorded speed, and how the Sun’s energy and Earth’s rotation play their parts.
