Weather Facts: Why so windy?

Posted: Updated:

Shirley Thompson of Austin was wondering if the recent wind events are normal and why they are happing so much in the last few weeks.

So what produces wind? The difference in air pressure is the answer. Air pressure is caused by Earth's gravity pressing down on the air.

When we talk about high pressure that means more weight is pushing down on the air so usually the clouds can't grow and the skies remain clear with calm winds.

With low pressure less weight is pushing down on the air so it begins to rise leading to clouds formation. With low pressure approaching the winds usually increase.

When the low and high are farther apart the air won't be funneled into small spot so the winds will be light.

When the pressure changes drastically across a short distance expect a strong wind. The air is being forced into a small area producing a natural wind tunnel.

During the spring there is always a battle going on between cold and warm air. So more storm systems and fronts develop more frequently and move across the country very quickly. This is when Texas is stuck in a squeeze play with low and high pressure giving us windy conditions every three or four days.
