Sažetak
In the framework of the international project CC-WaterS* three karstic aquifers at the eastern Adriatic coast are selected as test beds in Croatia: the lake Vrana, the Bokanjac and the Blato catchments. Air temperature and precipitation are analysed as basic input parameters used in hydrological calculations for water supply estimates. Analyses of present climate (1961-1990) contain air temperature and precipitation intra-annual variability and extremes and their temporal variations during the period 1951-2009 on monthly, seasonal and annual scale for stations within catchments. This paper presents the results for Bokanjac at the middle Adriatic coast. In the second part of this paper, climate is analysed in simulations of three regional climate models. Comparison of simulations of present climate with these three models, local observations on stations in meteorological network of Meteorological and hydrological service of Croatia and time series from E-OBS database points to a need for bias correction. In thise sense, statistical bias correction has been applied to all model simulations when compared to E-OBS values. Since there are differences present between E-OBS and local observations, further simple adjustment is developed. Climate change definied as a difference between future climate (2021-2050. and 2071-2100.) and present climate (1961-1990.) in all three models points towards temperature increase in all three locations. On the other hand, trend in precipitation amount points to higher variability in sense of sign and amount of change which also depends on model and season.
