The pros and cons of wind

ST. PAUL, Minn. -- The American flag is whipping. The long grass is blown over. It's been a breezy few days.

So where does the wind come from?

"Where it's really warm air which tends to rise and you get lower pressure. When it's cold the air sinks and you get high pressure. So, if you have two very different air masses close to each other, you're going to get really high pressure and really low pressure in close proximity and that's going to cause very strong winds," said Dr. Kenny Blumenfeld, a Climatologist with the Minnesota Department of Natural Resources.

So, is March typically a windier month for us?

"Yeah, we do see a lot of these gusty types of systems in late February, March, and April, and then again in the fall because the pattern of the air mass is changing," said Blumenfeld.
