Tornado frequency has increased across the eastern third of the United States and especially across the mid-South, according to a new study in the journal Climate and Atmospheric Science.
While tornadoes have increased in the East, there has been a notable decrease in twister activity across a large chunk of the Southern Plains of Texas and Oklahoma as well as the high plains of Colorado. These focal zones are among a broad downward trend across the Plains — historically known as tornado alley.
These are problematic changes, given the tendency for the shift to place increased tornado activity over a particularly vulnerable region, the study says. It found the starkest increase in tornado frequency across a region including Mississippi, Alabama, Arkansas, Missouri, Illinois, Indiana, Tennessee and Kentucky.
