[font size=3]BOULDER, Colo. At century's end, the number of summertime storms that produce extreme downpours could increase by more than 400 percent across parts of the United States including sections of the Gulf Coast, Atlantic Coast, and the Southwest according to a new study by scientists at the National Center for Atmospheric Research (NCAR).
The study, published today in the journal Nature Climate Change, also finds that the intensity of individual extreme rainfall events could increase by as much as 70 percent in some areas. That would mean that a storm that drops about 2 inches of rainfall today would be likely to drop nearly 3.5 inches in the future.
"These are huge increases," said NCAR scientist Andreas Prein, lead author of the study. "Imagine the most intense thunderstorm you typically experience in a single season. Our study finds that, in the future, parts of the U.S. could expect to experience five of those storms in a season, each with an intensity as strong or stronger than current storms."
Extreme precipitation events affect our infrastructure through flooding, landslides and debris flows, said Anjuli Bamzai, program director in NSFs Directorate for Geosciences, which funded the research. We need to better understand how these extreme events are changing. By supporting this research, NSF is working to foster a safer environment for all of us.
