Modelling Regional Climate Change in Germany

A series of regional climate simulations using the regional climate model COSMO-CLM (CCLM) have been carried out at the Institute for Meteorology and Climate Research (IMK) of Karlsruhe Institute of Technology (KIT) (Panitz et al. 2010). These simulations span the years 1971–2000 to represent the climate of the recent past and the years 2011–2040 to analyse the climate change in Southwest Germany during the next few decades. A second set of simulations covering all of Germany, have been carried out for the CEDIM-project “Hochwassergefahr durch Klimawandel”, to assess possible changes in flood hazard in the near future. Model validation, results for changes in temperature and precipitation statistics, and statistics on the computational resources used at the HLRS facitilites are presented.
