As the Wind Blows…

Monday was one of the windiest days in quite some time.  Here is a break down of some of the highest gusts recorded over the course of the day.  Click here… 

Lets talk more about the wind. 

As the sun warms the Earth’s surface, the air warms as well. Some parts of the Earth receive direct rays from the sun all year and are always warm. Other places receive indirect rays, so the climate is colder. Warm air, which weighs less than cold air, rises. Then cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow. 

Difference in atmospheric pressure causes the wind to blow. Wind usually blows from high pressure to low pressure. The differences in atmospheric pressure can be caused by uneven heating of the Earth’s surface (mentioned above), synoptic scale or localized scale forcings.

You always see these movements nearing a forecast temperature change.  For instance, temperatures were in the 70s over the weekend.  Monday we had the gusty winds all day and most of the night.  Our highs on Monday and Tuesday were in the low 60s.

Use this a tell tell sign of weather changes.  Always remember if it is a very windy day a temperature change is on the way…
