Observed and projected changes in the dry spells - Statistics over Croatia

Drought in Croatia causes the highest economic losses inflicting serious damages, especially in agricultural sector. Present study performs a systematic analysis of dry spells (DS) in Croatia. DS are defined as consecutive sequences of days having daily precipitation less than a given precipitation-per-day threshold. Here, a commonly used threshold in climate and agriculture practice, that of 5 mm is used. Daily precipitation data from a dense national rain-gauge network (forming seven climatological regions) and spanning the time period 1961–2015 are employed. The spatial and temporal characteristics of mean and maximum seasonal and annual DS are analyzed as well as recent changes in DS using the trend estimations by means of Kendall' tau method. Additional period 1971–2000 is defined. For this period both observation based DS and regional climate models' based DS analysis is performed. Regional climate model RegCM in the present study covers the EURO-CORDEX domain, and is forced at its boundaries by the four CMIP5 global climate models. RegCM applies 12.5-km horizontal resolution, resulting in a realistic orography and land-sea structures over Croatia. For the 1971–2000, RegCMs systematic errors in terms of the DS statistics will be examined. Finally, projections and future changes in the DS statistics will be based on the RegCM simulations under the high and medium greenhouse gases concentration scenarios (i.e., RCP8.5 and RCP4.5) with the focus on the climate change signal between 1971–2000 and two future periods, 2011–2040 and 2041–2070.
