barometric pressure = wind

Interesting pressure map this afternoon. Don't believe I've ever seen one with so many isobars so close together. Michagan must be getting a bit of wind.

Re: barometric pressure = wind

Not sure where it ended up at yesterday but it was forecast to be the lowest or next to lowest recorded pressure in MN . Similar to what would be found in a hurricane.

Got both generators ready. Secured doors on all buildings. Frankly it was a non event, gusty winds & light rain. We were blessed here in Alliance, Oh...

Re: barometric pressure = wind

Very strong winds here at Lino Lakes, turned all of the floatplanes sideways on their tiedowns, everything from a C206 on Whip 3900's to champs.

Re: barometric pressure = wind

We were 600 miles away from the center of that giant low yesterday, and we still had winds that were flipping trucks off the Interstate. Amazing.

My question: I know the theory of low pressure in a hurricane (hot water), but how does a low that deep develop over...Canada?

Re: barometric pressure = wind

All winds are a result of temperature differences. The sun heats, or doesn't, and the stronger the difference in temps the stronger the pressure differentials. I assume there must have been some (relatively) warm air over Canada somewhere, and some very very cold air somewhere else. I myself have always been a little miffed at the Canadians sending their cold air down to Pennsylvania each Winter! ;-))
I went hunting in northern Saskatchewan several years ago, in the late Fall, early Winter; that was an amazing experience, hit -30 degrees Farenheit every night, and a high of about 0 Farenheit!! We lived in a tent for the week...
