Extreme rainfall events in the Northeastern USA become more frequent with rising temperatures, but their intensity distribution remains stable

Abstract Both intensities of individual extreme rainfall events and the frequency such are important for infrastructure planning. We develop a new statistical value model, PGEV which makes it possible to use high quality annual maximum series data instead lesswell checked daily estimate trends in intensity separately. The method is applied maxima from NOAA Atlas 14, Volume 10, dating approximately 1900 2014, showing that majority 333 rain gauge stations Northeastern USA increases as mean temperature increases, but there little evidence distribution events. median corresponds rainfalls becoming 83% more frequent each centigrade degree increase. Naturally, increasing also increase yearly or 10-yearly risks very Three other large areas contiguous USA, Midwest, Southeast, Texas, studied, show similar weaker than those Northeast.
