Title: Reclip:century - a project conducting 21st century regional climate simulation runs focussing on the Greater Alpine Region
Abstract: The scenario results will demonstrate the range of climate evolution due to different greenhouse gas increase trends. The regional climate results conducted through dynamical downscaling of simulation runs from two General Circulation Model (GCM) simulation runs with two regional climate models (RCMs). A one-way double nesting approach is applied by the two RCMs COSMO CLM and MM5: the domain for the first nesting task is entire Europe and the surrounding areas with a spatial resolution of 30 to 50 km grid-spacing, depnding on the forcing data resolution. The second domain covers the Greater Alpine Region with a resolution of 0.09° or 10km grid-spacing. The GCMs, providing forcing data, are the German ECHAM5-MPI-OM (with approx. 100 km grid-spacing) and the UK HADCM3 (with approx. 200 km grid-spacing). Three IPCC greenhouse gas scenarios (A1b, B2 and A2) for the time range 2000-2100 will be applied to compare the different greenhouse gas increase effects on regional climate. ERA40 reanalysis data for 1961-2000 GCM resolution will provide forcing for the hindcast model runs derived by the 2 RCMs. Observation data sets from HISTALP, CRU and Frei will be used to evaluate the hindcast simulations.
