Research forecasts increased chances for stormy weather

A Purdue University-led team, including Earth and Atmospheric Sciences faculty members R. Jeff Trapp and Noah Diffenbaugh, used climate models to examine future weather conditions favorable to formation of severe thunderstorms — those that produce flooding, damaging winds, and hail and sometimes spawn tornadoes.
“It seems that areas in the U.S. prone to severe thunderstorms now will likely have more of them in the future,” says Trapp. The study found that by the end of this century the number of days that favor severe storms could more than double in locations such as Atlanta and New York. The study also found that the increase in storm conditions occurs during the typical storm seasons for these locations and not during dry seasons when such storms could be beneficial. <more>
