• TORNADOES AND TRAILER PARKS: A STATISTICAL CORRELATION.
• Some states are more prone to victimization by tornadoes and hurricanes than others. Expert meteorologists contend that Kansas, for example, is so often buffeted by tornadoes because of the alignment of the Rocky Mountains, the flatness of the great plains, and the direction of prevailing winds (1). ... Their analysis is incomplete because it does not consider the popular notion that tornadoes are most common, simply, in states with many mobile homes (2). Below I attempt to justify, and, if possible, quantify this and other common beliefs about tornadoes.
• A state-by-state comparison was made between the number of tornadoes (3) and purchases of mobile homes (4).
• Tornadoes and Trailer Homes.
• Tornadoes and hurricanes are indeed most frequent in states with many mobile homes. For instance, eight states are in the top eleven for both prefab homes and tornadoes. ... Indiana ranks second in tornadoes and first in mobile homes. ...
• However good the correlation between the presence of trailer parks and tornadoes, it is not perfect. To account for the imperfections, I analyzed another popular myth (8): the idea that states with many large cities have fewer tornadoes -- it is claimed that the buildings act as windblocks. ...
• The occurrence of tornadoes seems to depend on both the number of mobile homes and the absence of large cities. ... In contrast, California has many large cities (only 19,500 square miles between them), and is subject to very few tornadoes (0. 25 tornadoes/10,000 square miles/year). ...
•   Also, Mississippi has an increase in tornadoes expected by its lack of cities.   However, because there are no cities (and thus its rural land area is infinite), one might expect there to be a constant scouring of the state by violent storms, all tornadoes, all the time. ...

• It is likely that the strongest tornadoes, such as the F5 that hit the Oklahoma City area on May 3, 1999, sometimes exceed the top speed in the scale.

• Tornadoes can occur almost anywhere on earth, but in most places, their frequency is very low. For instance, in Holland, we get only a few F0 tornadoes per year, and F3 to F4 tornadoes only once every 30 years or so on average. However, in North America, tornadoes occur with a relatively high frequency, as the conditions there in spring and summer are often just right for supercell storms to develop. Down the middle of North America runs a strip of land, roughly from Arkansas to Colorado and all the way from Texas to North Dakota, which is called Tornado Alley, due to the high number of tornadoes striking there. ...
