In this study, trends in annual and seasonal precipitation amounts in Croatia are discussed. This discussion is followed by trend analysis in seven in- dices of precipitation extremes, which indicate intensity and frequency of ex- treme rainfall events. These indices have been proposed by World Meteorologi- cal Organisation and are calculated using daily precipitation amounts. The data sets used in this study cover the period 1901–2008 at five meteorological stations distributed among different climate conditions in Croatia: continental, mountainous and maritime. The trends are estimated by a simple least squares fit of the linear model and tested for statistical significance by a non-paramet- ric Mann-Kendall test. The time series with significant trends are identified, and a Sneyers progressive analysis is then performed to determine the begin- ning of the trend. The time series analysis of coefficients of variation in consec- utive 30-year periods indicates the variability in precipitation. The extreme quantiles for annual one-day and five-day precipitation maxima have been esti- mated by the Generalised Extreme Value (GEV) distribution and discussed in relation to the original time-series. The results show a downward trend in an- nual precipitation amounts since the beginning of the 20th century throughout Croatia, which agrees with the drying trend observed across the Mediterra- nean. Precipitation amounts have large interannual variability, on both annual and seasonal scales. By the end of the 20th century, the precipitation variability decreased in the north-western Croatian mountainous and northern littoral re- gions and the eastern lowlands. The Dalmatian islands experienced increased variability since the middle of the 20th century. In regions of drying, such as Croatia, there is no evidence of major secular changes in precipitation extremes that are related to the high amounts of precipitation and the frequency of heavy rainfall days over the majority of Croatia.
