The paper deals with the precipitation variability areas of Croatia with pluviometric regime. Precipitation variability was analyzed using yearly and monthly values of the mean relative variability for 18 stations in the period 1950-2007. The research results showed that there is relatively large range of precipitation variability in the researched area. The highest precipitation variability was recorded in Lastovo and the lowest in Parg station. The primary maximum of precipitation variability in the northern Adriatic area is in October, while in the southern part of the Adriatic maximum variability occurs during the summer months - July or August. The minimum variability in most of the stations with maritime pluviometric regime occurs in April, except in the central part of the Adriatic, where it occurs in November. The lowest precipitation variability is in the mountain region of Croatia. The highest values of precipitation variability occur during summer months in the southern part of Adriatic. The values of precipitation variability in the Kvarner region are relatively higher than the variability of the surrounding stations in almost all months. [ABSTRACT FROM AUTHOR]

This paper investigates the changes in precipitation levels in Croatia that can be observed since the mid 20th century. Based on the data from 22 weather stations, linear trends show very little oscillation for the period 1950-2010. In eastern Croatia, a slight increase was recorded, while a slight drop or stagnation was evident in other parts of the country. However, were such trends to continue, they could have long-term geographic consequences. In the analytical period, it is possible to determine cyclical changes in the annual levels of precipitation.
