Project EC FP6 CECILIA – Central and Eastern Europe Climate Change Impact and Vulnerability Assessment is studying the impact of climate change in complex topography of the Central and Eastern Europe in high resolution. The impacts on agriculture, forestry, hydrology and air-quality are studied. Resolution of regional climate simulation is an important factor affecting the accuracy of dynamical downscaling of the global changes. Especially the extremes are strongly dependent on the terrain patterns as shape of orography or land use, which can contribute to extreme temperatures or precipitation appearance. In connection with 2002 floods in Czech Republic we started to analyse whether RCMs are capable to reproduce extremes, which can be quite important feature of changing climate. Here the reliability of the RCMs in reproducing extremes is again studied in the experiment with the perfect boundary condition driving in simulations for EC FP6 project CECILIA dealing with climate change impact and vulnerability assessment in Central and Eastern Europe. The preliminary results of simulations performed with the resolution of 10 km using based on reanalysis ERA 40 are presented and compared with previous experiments in coarser resolution with the emphasis on extreme temperature and precipitation characteristics, validation based on the station observations from the Czech Republic.
