Abstract The Coordinated Regional Climate Downscaling Experiment is a framework devoted to coordinate international efforts on regional climate simulations. Region 8 of the CORDEX domains basically covers the Central Asia with corners of the domain at (11.05°E; 54.76°N), (139.13°E; 56.48°N), (42.41°E; 18.34°N) and (108.44°E; 19.39°N) with a horizontal resolution of 50 km. In the study, the results of an experiment with the RegCM4.0 model that is ran for analysis of extreme precipitation is presented. The experiment consists of one simulation from 1970 to 2000 by using the ERA40 reanalysis data as boundary condition, and another simulation for the period 2070-2100 using the ECHAM5 A1B scenario data as forcing. Between these two experiments we have determined the probable changes in the frequency of the extreme events for the Region 8 of CORDEX. Key Words: Climate change; extreme events, Central Asia, model projections; regional climate downscaling.
