Da bomb

Via The Map Room, this image of the storm that just blew through the Midwest. (Click on the image to see a large version, which may take a minute to load.)

FDR's first inaugural

Says NASA:

The storm that swept across the center of the United States on October 26 and October 27, 2010, was memorable to those who experienced it because of its strong winds, rain, hail, and widespread tornadoes. Meteorologists get excited about the storm because it set a record for the lowest pressure (not associated with a hurricane) measured over land in the continental United States. At 5:13 p.m. CDT, the weather station in Bigfork, Minnesota recorded 955.2 millibars (28.21 inches of pressure). Pressure is one indicator of a storm’s strength, and this measurement corresponds to the pressure seen in a Category 3 hurricane.

This image, taken by the GOES satellite on October 26, shows the storm system circling around the area of extreme low pressure. Such extratropical cyclones form over the United States in the spring and fall, when the temperature difference from north to south is large. Warm, high-pressure air rushes toward the cooler, low-pressure air in the north. Because the Earth is rotating, the air moving in ends up circling the area of low pressure, creating the cyclone shown in the image. The intensity of the storm is determined by the pressure difference between the center and the outer edges. Extreme low pressure in the center of the storm, therefore, is an indicator that the storm was very intense. ...

The cyclone formed very quickly on October 26, taking a distinctive comma shape as the day went on. The storm developed so quickly, in fact, that it is classified as a bomb, an extremely fast developing storm (dropping at least one millibar of pressure per hour for 24 hours), more common over water than land.

The storm was also huge. Though the area of low pressure is centered over the Upper Midwest, the storm reached from the Gulf of Mexico into Canada, and from the Rocky Mountains to the Atlantic Ocean.

No global warming, no siree.

We missed the worst of it here. It's amazing how Lake Superior creates this protective bubble around those of us who live very close to it. Sure it was windy and we had monsoon rains, but not far from here it was snowing. And it really is a bubble. There are times that a storm's moving in from the West (for me, the Lake is to the East) and you can watch it roll, roll, roll looking menacing...and then it just stop 5-10 miles from the shore. Bounces off and rolls away.

Of course if the storm comes from the Northeast, we're fucked. Not only do we get hammered, but those storms tend to then be pulled back out to sea where they gather strength. When they try to push South and West again, they're trapped and guided by the Keweenaw Peninsula and roll right back over us. There are times where we get pounded by the same storm every day for a week or more. You can actually watch it moving over the Lake during the off times.

I live in an area of meterological oddity. For example, during the big storm day i not only saw two double rainbows, but at one point it was 60 degrees, the sun was shining and the rain was falling at monsoon strength. Not to mention that you can go from USDA zone 5 to zone 3 in less than 15 miles.

the moderating influence of large bodies of water :biggrin:

Volcanic oceanic islands (i.e. the ones where you can get more than 200 ft above sea level) may well be the place to be fifty years from now, unless you like the idea of moving to the Arctic.
