Wind up

There’s got to be some reason why all the tornadoes around here head straight for Moore, and maybe this has something to do with it:

Areas where landscape shifts from urban to rural or forest to farmland may have a higher likelihood of severe weather and tornado touchdowns, a Purdue University study says.

An examination of more than 60 years of Indiana tornado climatology data from the National Weather Service’s Storm Prediction Center showed that a majority of tornado touchdowns occurred near areas where dramatically different landscapes meet — for example, where a city fades into farmland or a forest meets a plain.

You mean, something like this?

Those of us in the middle of the Big Town are even now emitting unseemly sighs of relief.

    I always thought that mobile home parks caused tornadoes :)

    I think usage choices tend to follow the same kinds of differences in terrain and subclimate that might tend to determine where a tornado will go — but you just know there will be people who would argue that changing the land use in a tornado-prone locale would change its tornado-prone-ness.

    And I’ll bet you anything they’ll be the same people who believe global warming causes harsh North American winters and the increase of ice in “East” Antarctica.

    I’ve had a number of the long-timers here tell me that the construction of Lake Texoma led to less risk of tornadoes and also many severe storms skirting to the north of us. No idea if the lake is big enough to have a “lake effect,” but it does seem a lot of bad weather just misses us.
