The study examines how regional climate models (RCMs) capture links between atmospheric circulation and surface air temperatures over Central Europe in control climate (1961-1990), and how these links may change in future climate change scenarios (2071-2100). To compare the performance of the individual RCMs and dependence of the results on the driving GCM, additional combinations of an RCM with various driving GCMs will be analysed. The first aim is to identify errors in RCM-simulated distributions of circulation indices/types in individual seasons in comparison to observations. The next step is to evaluate changes of the simulated atmospheric circulation in future climate scenarios. The final goal is to identify errors in simulated daily temperatures under particular circulation indices/types in the control period, and to evaluate changes of the relations between atmospheric circulation and surface air temperatures in the future climate scenarios in comparison to the control climate.
