Dr. Paul Knapp, professor in the Department of Geology, co-authored research that examines the drought-busting capability of tropical cyclones, as reported by phys.org. The lead author of this research was Dr. Justin Maxwell of Indiana University at Bloomington; the other co-authors were from the University of West Florida and Appalachian State University.

According to the research, the category of tropical cyclones includes hurricanes, tropical storms and tropical depression.  The study analyzed weather records for the Southeast going back to 1895, charting what they called TCDB or tropical cyclone drought busters. They found that tropical cyclones ended about 13 percent of droughts on the Gulf and south Atlantic coasts.
