Abstract: In order to satisfy the continuous urging demands for updated and relevant information from various impact researchers, end-users, and decision makers, the RegCM4.3 model is used taking into account the new RCP4.5 and RCP8.5 radiative forcing scenarios to provide climate projection for Hungary with 10 km horizontal resolution. Overall, the results suggest significant warming in Hungary. The greatest temperature increase is likely to occur in summer, which is why the projected changes in warm extremes are also analysed in this study.

Keywords: climate projection; RCP4.5; RCP8.5; regional climate model; warming trend; extreme temperature indices; daily maximum temperature; daily minimum temperature; temperature distribution; Hungary.
