USA\s infamous \Tornado Alley\ may be shifting east

Oklahoma is apparently exporting tornadoes to Iowa and Missouri

(AP) — A new study finds that over the past few decades U.S. tornadoes have shifted — decreasing in Oklahoma, Texas and Kansas but spinning up more in states along the Mississippi River and farther east.

The study is in Wednesdays journal Climate and Atmospheric Science. It sees a slight decrease in tornado activity in the Great Plains, with the biggest drop in central and eastern Texas.

Study: More tornadoes for Tennessee, Kentucky, and other Dixie Alley states

The study found it is increasing most in Alabama, Arkansas, Kentucky, Illinois, Indiana, Iowa, Louisiana, Mississippi, Missouri, Tennessee, Wisconsin and parts of Ohio and Michigan. Lead author Victor Gensini of Northern Illinois University says the increases could be deadly because more people live in those states.

NASHVILLE, Tenn.–A new study in the Climate and Atmospheric Science Journal finds trends are increasing for tornadoes in Tennessee, Kentucky and other states in “Dixie Alley.”

Researchers with Northern Illinois University say the area traditionally called “Tornado Alley” is extending east to include Tennessee, Kentucky, Mississippi, Alabama, Arkansas, Missouri, Illinois, and Indiana.

Researchers based the findings in part by using Theil-Sen slope analysis, which is a linear trend estimator. They also used Kendalls test for statistical significance.

Looking and the trends and environments, researchers say increases in tornado frequency in the mid-south combined with environment and population density poses increased risk to an already vulnerable population. Researchers add this places the mid-south as having the “greatest potential for increased tornado disasters by the end of the century.”

These impacts are heightened due to increases in population, which increases those at risk and exposure. Researchers say the trends are consistent with climate change
