You Asked 4 It: What causes wind?

ALBUQUERQUE, N.M. -- It's no secret that the windy season has arrived in New Mexico, but one KOB viewer asked what's behind all of it in the first place.
"Where does wind come from?" Eddie asked.
Here's the answer.
Differences in air pressure throughout the planet create the wind. This can happen many different ways, but differences in temperature can make it happen.
Let's use the Rio Grande as an example. The air above that water is going to heat more slowly throughout the day. It's going to remain cooler and denser, which means it's heavier on the surface creating high pressure.
On dry land, things heat up a lot more quickly on rocks and soil, even concrete. That means the hot air is starting to rise creating low pressure at the surface.
But this is on a very small scale. Wind forms on a much larger scale. Sea breeze, one form of wind, happens because the cool heavy air creates high pressure over the water. Hotter temperatures over the land cause the air to rise, creating low pressure.
This movement of air creates the wind.
