| Zusammenfassung |
| We present a study of different configurations of the Weather Research and Forecast model
for the Euro-CORDEX area with different microphysical, convective subgrid and planetary
boundary layer parameterizations. The resolution of the experiments are 0.04°, 0.11° and
0.44°. Boundary conditions are provided by ERA-Interim re-analysis data. Monthly and daily
statistics for the year 1979 are compared in order to determine the best configuration
for reproducing precipitation climatology and precipitation statistics, particularly
for the Alpine region. Our results show that while local precipitation patterns are
well reproduced by the model, the model presents a positive bias in average annual
precipitation. We find that a high model resolution (at least 0.04°) and explicitly resolved
convection are needed to properly represent the observed precipitation distributions. |
