Abstract:

{In the present study, the dynamical downscaling technique was applied in the Advanced Weather Research and Forecasting numerical model WRF-ARW, to investigate and validate the performance of different physics parameterizations. The WRF model, was forced by ERA-INTERIM reanalysis data, for a short period of one year (January 2002-December 2002), over the area of the MED-CORDEX domain of 20 km horizontal resolution, downscaled to the domain of Greece with grid spacing of 5 km. Simulations with the Yonsei University (YSU) and Mellor-Yamada- Janjic (MYJ) schemes for boundary layer parameterizations were chosen, along with the corresponding surface layer schemes, as well as, cumulus physics schemes of Kain-Fitsch and Grell-Devenyi. The results of the model simulations have been compared with all available station measurements from the European Climate Assessment and Dataset (ECA&D) for the daily precipitation and 2-m air temperature, through the computation of statistical metrics. The study led to a more reliable choice of physics configurations schemes for the WRF model, in order to simulate future climate model experiments to assess the impact of climate change over the domain of interest.}
