Development of an extreme wind-driven rain climatology for the southeastern United States using one-minute rainfall and peak wind speed data

Abstract A method is presented to obtain the climatology of extreme wind speeds coincident with occurrence rain. The simultaneous and rain can force water through building wall components such as windows, resulting in damage insured loss. To quantify this hazard, value distributions are fit peak 3-second speed data recorded during 1-minute intervals specific reported intensities. This improves upon previous attempts wind-driven that computed rainfall intensity probabilities independently used hourly which cannot assure represents only a several-second interval within hour accumulated over entire hour. applied across southeastern U.S., where hazard most pronounced. For lowest intensities, extremes agree published values ignore occurrence. Such correspondence desirable for aligning rain-intensity-dependent windspeed return periods established statistics. Maximum 50-year period conjunction intensities ≥ 0.254 mm min −1 exceed 45 ms swath from Oklahoma Gulf Coast at stations along immediate Atlantic Coast. >2.54 maximum, decrease 35 but occur similar area. methodology also outside Southeast demonstrate its applicability incorporating U.S. standards.
