Following what is called a MONSTOR Tornado in South Oklahoma City surburb of Moore, OK......
. . . . .After a relatively quiet start to the tornado season, tornadoes have been erupting from Texas to Minnesota over the past week. A cold front advancing to the east appears to be to blame. That pocket of cold air has run into warm air from the Gulf, causing the warm air to rise and spawning powerful thunderstorms. "It's kind of like the perfect setup,"
. . . .the geography of America's midsection makes it more prone to tornadoes than any other region on Earth. That's because the Rocky Mountains tend to impede the eastward flow of moist air, while the Great Plains allow frigid Arctic air to stream southward from Canada and meet up with warm, humid air from the Gulf of Mexico. It's the collision of that warm and cold air that breeds powerful twisters.
"Tornado Alley" generally refers to the region centered in Texas, Oklahoma, Kansas and points north, where tornadoes are most frequent — but multiple studies indicate that the deadliest twisters occur to the east, in a region that's come to be known as "Dixie Alley."
Before and After Neighborhood Pictures.....
The reasons for that have to do with geography and demographics as well as meteorology in the southeastern United States: Storms tend to move faster
, and they're more likely to strike at night. There are more trees and other obstructions to raise havoc. Population densities are generally higher, and the region has many manufactured homes that lack basements in which to take shelter.
The United States has the highest incidence of tornadoes, with an average of more than 1,000 every year, according to the National Climatic Data Center. But other regions of the world have twisters as well. Canada is No. 2 with about 100 per year, followed by northern Europe, western Asia, Bangladesh, Japan, Australia, New Zealand, China, South Africa and Argentina. Britain has more tornadoes than any other country, relative to its land area.
