英文摘要: High-resolution (4 km; hourly) regional climate modeling is utilized to resolve March-May hazardous convective weather east of the U.S. Continental Divide for a historical climate period (1980-90). A hazardous convective weathermodel proxy is used to depict occurrences of tornadoes, damaging thunderstormwind gusts, and large hail at hourly intervals during the period of record. Through dynamical downscaling, the regional climate model does an admirable job of replicating the seasonal spatial shifts of hazardous convective weather occurrence during the months examined. Additionally, the interannual variability and diurnal progression of observed severe weather reports closely mimic cycles produced by the regionalmodel.While this methodology has been tested in previous research, this is the first study to use coarse-resolution global climate model data to force a high-resolution regionalmodel with continuous seasonal integration in the United States for purposes of resolving severe convection. Overall, it is recommended that dynamical downscaling play an integral role in measuring climatological distributions of severe weather, both in historical and future climates. © 2014 American Meteorological Society.
