Evaluation of the Sensitivity of the Weather Research and Forecasting Model to Parameterization Schemes for Regional Climates of Europe over the Period 1990–95

摘要: AbstractThe Weather Research and Forecasting model (WRF) is used to downscale interim ECMWF Re-Analysis (ERA-Interim) data for the climate over Europe period 1990–95 with grid spacing of 0.44° 12 combinations physical parameterizations. Two longwave radiation schemes, two land surface models (LSMs), microphysics planetary boundary layer (PBL) schemes have been investigated while remaining physics were unchanged. WRF simulations are compared Ensemble-Based Predictions Climate Changes their Impacts (ENSEMBLES) observations gridded dataset (E-OBS) air temperatures (T2), precipitation, mean sea level pressure (MSLP) in eight subregions within domain assess performance different parameterizations on widely varying regional climates. This work shows that T2 modeled well by high correlation coefficients (0.8 < R 0.95) biases less than 4°C. greatest sensitivity models, som...
