ABSTRACT:
In August 2005. especially in the first decade, eastern Adriatic coast experienced two weather disturbances, followed by sudden temperature decrease and heavy precipitation, unusual for that part of the summer. Statistical evaluation of these unusual weather phenomena was carried out by two statistical methods: standard deviation criterion and percentile criterion, using data from five main meteorological stations: Rijeka (the coast of the Kvarner bay), Mali Lošinj (the island in the Kvar - ner bay), Zadar (the northern Dalmatian coast), Hvar (Dalmatian island) and Dubrovnik (southern Adriatic coast area). The data used for the analysis were average daily air temperature in August (1948-2005) and average precipitation in the first decade of August (1961- 2005). Standard climatological period 1961-1990 was used as a reference one. In 57 years, there were only 7 years with first decade of August colder than the first decade of August 2005, at least at one of the stations. Only two years (1955 and 1976) had a first decade of August colder than the first decade of August 2005 at all of the selected stations. According to percentile criterion, the first decade of August 2005 was in the category very rainy (>91%) at the stations Rijeka and Mali Lošinj (northern Adriatic). Stations Zadar, Hvar and Dubrovnik (middle and southern Adriatic) were in the category rainy (>75%).
