This paper deals with the parallel analysis of monthly precipitation series and drought indices in Croatia for the 1951-2010 period. The monthly precipitation amounts for the nine meteorological ...stations that are representing the majority of climate types in Croatia were used. In order to determine the precipitation variability features and the drought occurrence frequency, the analysis was conducted over four 30-year periods (1951-1980, 1961-1990, 1971-2000 and 1981-2010). As a measure of drought, the Standardized Precipitation Index (SPI) and the Rainfall Anomaly Index (RAI) were used. The precipitation amount decrease and the variability increase were determined for many of the analysed stations, but there are significant regional and seasonal differences. Using RAI and SPI6 several drought episodes in the research period were determined. The drought occurrence in the warm part of the year (April to September) that corresponds to the vegetation period in Croatia was analysed.
Rad se bavi varijabilnošću padalina u dijelu Hrvatske s maritimnim pluviometrijskim režimom. Varijabilnost padalina analizirana je korištenjem godišnjih i mjesečnih vrijednosti srednje relativne ...varijabilnosti za 18 postaja od 1950. do 2007. godine. Utvrđeno je da godišnja varijabilnost padalina ima relativno veliki raspon – najveću varijabilnost padalina ima postaja Lastovo, a najmanju postaja Parg. U godišnjem hodu varijabilnosti padalina glavni maksimum varijabilnosti je na području sjevernog Jadrana u listopadu, dok se prema jugu maksimum varijabilnost javlja u ljetnim mjesecima – srpnju ili kolovozu. Glavni minimum varijabilnosti u većini postaja s maritimnim pluviometrijskim režimom javlja se u travnju, osim na postajama srednjeg Jadrana, gdje se javlja u studenom. Najmanju varijabilnost padalina ima područje Gorske Hrvatske u gotovo svim mjesecima. Najveće vrijednosti varijabilnosti padalina javljaju se ljeti na području južnog Jadrana. U gotovo svim mjesecima varijabilnost padalina na području Kvarnera je relativno viša u odnosu varijabilnost padalina okolnih postaja.
The paper deals with the precipitation variability areas of Croatia with pluviometric regime. Precipitation variabilitywas 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 variabilitywas 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 summermonths in the southern part of Adriatic. The values of precipitation variability in the Kvarner region are relatively higher than the variabilityofthe surrounding stations in almost all months.
Based on the analysis of water supply, tourist traffic and climatic parameters, the paper assessed the sustainability and possibilities of adapting the water supply system in the future, considering ...the simultaneity of the peak loads on the water supply system with dry periods in the warm part of the year. The research covers islands from the northern and middle part of the Adriatic Sea (Croatia), which represent examples of islands with Cfa and Csa climates with significant differences in resource reliance on the island and coastal water resources. Given that previous climatological research indicates an increase in spring and summer temperatures on the Croatian coast, as well as spatial and seasonal changes in the amount of precipitation with a decrease during the summer months, the paper describes the possibilities of adapting current and alternative sources of water supply systems on the islands.
U radu su na temelju analize vodoopskrbe, turističkog prometa i klimatskih parametara procijenjene održivost i mogućnosti prilagodbe vodoopskrbnog sustava u budućnosti s obzirom na istovremenost vršnih opterećenja sustava sa sušnim razdobljima u toplom dijelu godine. Istraživanjem su obuhvaćeni otoci sa sjevernog i srednjeg dijela Jadranskoga mora (Hrvatska) koji predstavljaju primjere otoka s Cfa i Csa klimom uz značajne razlike u resursnom oslanjanju na otočke i obalne vodne resurse. S obzirom da dosadašnja klimatološka istraživanja ukazuju na porast proljetnih i ljetnih temperatura na hrvatskoj obali te prostorne i sezonske promjene količine padalina uz njihovo smanjenje tijekom ljetnih mjeseci, u radu su opisane mogućnosti prilagodbe trenutnih, ali i alternativnih izvora prihrane vodoopskrbnih sustava na otocima.

The study analyses the precipitation variability in Hvar and Crikvenica in the period from 1931 to 1990. These stations have a maritime type of the annual course of precipitation. The minimum value ...of the precipitation variability in Hvar is in autumn, in November, while the secondary minimum of the variability is in spring, in April. The primary maximum of variability is in summer, most often in July, while the secondary maximum is in March. In Crikvenica the minimum values of the precipitation variability in April and November are even, and the same is true for the maximum values of the variability in September and March. The value of the annual precipitation variability is higher in Crikvenica than in Hvar although Crikvenica has higher amount of precipitation. The location of the stations included in this research is relevant. In Crikvenica the variability is higher in autumn and winter. Monthly values of the mean relative variability coincide in the cold part of the year when the variability is only slightly higher in Crikvenica, while in the warm part of the year, with the exception of September, the variability in Hvar is significantly higher.
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 evidentin 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.
U radu se istražuje kakve se promjene u godišnjoj količini padalina u Hrvatskoj mogu utvrditi od sredine 20. stoljeća do danas. Na temelju podataka za 22 postaje linearni trendovi za razdoblje 1950. ...– 2010. pokazuju vrlo male promjene. U istočnoj Hrvatskoj evidentan je blagi porast; a u ostalim krajevima utvrđen je blagi pad ili stagnacija. Ipak; kada bi se takvi trendovi nastavili; dugoročno bi mogli imati geografske posljedice. U analiziranom razdoblju moguće je utvrditi i cikličke promjene godišnje količine padalina
Članek obravnava nekatere geografske vidike trajnostnega razvoja na območju severnega Jadrana v Republiki Hrvaški. Ta občutljiva regija se sooča s problemi urejanja prostora, oskrbe z vodo, ravnanja ...z odpadki, prometa in energetike, še zlasti v času turistične sezone, ko se močno povečajo obremenitve infrastrukture v obalnem območju, kjer je velika koncentracija prebivalstva in turističnih zmogljivosti. Dodatne okoljske probleme prinaša načrtovana gradnja naftovoda v okviru rusko-hrvaškega projekta Družba-Adria.
