Sažetak
The characteristics of summertime hot events in Croatia are examined by using regional climate model RegCM4. Model is forced over the EURO-CORDEX domain by ERA-Interim reanalysis for the period 1989-2008 and two different horizontal resolutions. First experiment is done for 50 km resolutions whereas in the second the resolution is increased to 12.5 km. Daily mean, maximum and minimum temperatures are analysed in order to define climate extreme indices during summer in Croatia. Number of summer days, warm and very warm days, warm and tropical nights, heat weaves and their duration are compared among two experiments. Results from both experiments are also compared with the daily E-OBS data as well as with the observed data from the Croatian meteorological stations. Although the model in both simulations generally overestimates observed results, the experiment on finer resolution better reproduce the spatial distribution of the analysed indices over Croatia.
