A recent study by scientists from Northern Illinois University (including a UGA geography department graduate) shows that the higher frequency of tornadoes is shifting to the east from the Plains towards the Southeast.

The researchers are not sure why this trend is occurring and are looking at both natural and human causes of the observed patterns.
