21st Conference on Climate Variability and Change


CCSM/WRF Regional climate simulations of extreme hydrologic events in Central America

Alex C. Ruane, NASA/GISS and Oak Ridge Associated Universities, New York, NY; and C. Rosenzweig and R. M. Horton

We present preliminary results from regional climate simulations over a large Central American domain, focusing on shifts in extreme hydrologic events. The Weather Research and Forecasting (WRF) model is driven by the NCAR Community Climate System Model (CCSM)'s 20th Century, A2, and B1 emissions scenarios at 3-hourly and 30km resolution on the Discover cluster at the National Center for Computer Services (NCCS). Drought and flood statistics from the 2020s, 2050s, and 2080s, when compared to the historical baseline, elucidate societal vulnerabilities and shifts in atmospheric patterns.
