Sažetak
We analysed the series of mean monthly and annual temperatures of the sea surface measured at three stations in the Croatian part of the Central Adriatic: (1) Split (1960 - 2019), (2) Hvar (1964 -2019) and (3) Komiža (1991 - 2019). In order to study the relation between sea surface temperature and air temperature, we also analysed air temperatures measured at the same three stations in the period from 1960 to 2019. The applied RAPS method revealed the existence of a sudden, statistically significant increase in sea surface temperatures at all three stations starting from 1998. A statistically significant increase in air temperatures at the analysed stations occurred slightly earlier, in 1992. An analysis of monthly time series of both sea surface temperatures and air temperatures showed an upward trend for each month of the year and was statistically significant for the period from April to August. A comparison of multi-annual averages of mean monthly air and sea surface temperatures showed that average sea surface temperatures were lower than average air temperatures in the period from May to August at all three analysed locations. The largest difference occurs in July, when average multi-annual air temperatures in Split and Hvar are 2.2ºC higher than average sea surface temperatures. In Komiža, the maximum difference is slightly lower, i.e. 1.6ºC. In the remaining months of the year, average sea surface temperatures are higher than average air temperatures. The greatest difference occurs in December, with average sea surface temperature by over 5ºC higher than average air temperature at all three locations.
