Spatial patterns and variability of dry spells in Croatia

Seasonal and annual dry spells are analysed employing daily precipitation data from 25 meteorological stations in Croatia. The analysis is based on four precipitation-perday thresholds (0.1, 1, 5 and 10 mm) and covers the time period 1961-2000. The climatology of dry spells indicates three main climatic regions: mainland, highland and coastal region. Attempting to find the joint spatial and temporal variations of mean and maximum dry spells in Croatia, the Empirical Orthogonal Function (EOF) analysis is performed. In order to fit the empirical frequency distributions of dry spells the goodness of fit of several statistical distributions is tested. A comprehensive analysis of time trends of mean and maximum dry spells is performed including a piecewise estimation of local trends by means of Kendall’s tau slope estimator.
