First of all, I'm pretty glad we live on a planet with an atmosphere. If that weren't cool enough, that atmosphere circulates. This is wind. Wind is amazing because it happens on a global and local scale!
Globally, the winds are caused by ocean currents. Deep, consistently-flowing ocean currents that flow from cool parts of the ocean to warm parts, or vise versa warm parts to cool, causes the air temperature above those parts to differ. That differing air temperature results in an imbalance of air temps, pressures and humidity levels, which cause wind! Ocean currents have names, and often have accompanying winds above them. What's kind of mind-boggling is that these currents exist because the water is blown by the winds....yet at the same time, the winds exist because the currents do. Whut.
