Dynamical and Statistical downscaling of Mediterranean climate: comparison and uncertainty assessment in the MED-CORDEX and HYMEX context. EGU conference, Vienna, april 2011

Abstract : This study presents the assessment and comparison of the two downscaling methods: Dynamic Downscaling (DD) and Statistical Downscaling (SD). Both methods are applied on a climatological study on the Mediterranean region. Hence, for the years 1989-2008, the ERA-Interim re-analyzes of mean daily values of 2-meter temperature and rainfall are dynamically downscaled using the Whether Research and Forecasting (WRF) model and statistically downscaled using the Cumulative Distribution Functions-transform model (CDF-t). In particular, the WRF model is evaluated in regards of two different horizontal resolutions (50km and 20km) and two different integrated Land Surface Models (Noah and RUC). Observations for the models evaluation are taken from the European Climate Assessment & Database (ECAD) and from the labeled hydro-meteorological stations attached to the HYdrological cycle in the Mediterranean Experiment (HYMEX).
