Weather Tidbits: What Causes Wind?

This Weather Tidbits explores how wind is formed. The first thing to understand is that air pressure is always to trying to reach a state of equilibrium or balance. Wind is formed in an attempt to restore balance from differences in air pressure. When the pressure is equalized, the wind will stop. Also, the greater the difference in pressure the stronger the wind. Weak winds happen when there is a small change in pressure; while strong winds occur when there is a large difference in pressure.
