Webster’s dictionary defines wind as “a natural movement of air of any velocity; especially: the earth’s air or the gas surrounding a planet in natural motion horizontally.” This is quite a lengthy definition for the atmospheric phenomena that messes up everyone’s hair. Or the thing that spreads all of the leaves that were once in a pile, back all over your yard. What causes the wind to blow?
The answer is the Pressure Gradient Force (PGF). When the isobars are packed tightly together on a constant pressure chart that means that in that area it will be more windy. When the isobars are a lot more spread out, the wind will be more calm.
This map made me wonder, is Chicago worthy of the name “The Windy City”?
According to the Washington Post, the top five windiest states are Nebraska, Kansas, South Dakota, North Dakota, and Iowa, respectively. Notice how Illinois does not make the list. It is hard to believe “The Windy City”‘s state didn’t make the top five. I searched for a list of the true “Windiest Cities in America”, this is where things got interesting!
Every list I found, had a different answer to what city is the windiest; however, they all agreed that it was not Chicago. Chicago rarely even reached the top 15 cities! This is where I would like to make a proposal.
Grand Forks had wind gusts of 39 mph yesterday and a max sustained wind speed of 32 mph. That is very windy! And the wind seems to be blowing everyday (due to that tight pressure gradient force). How about we nickname Grand Forks, “The New Windy City”?
