Sažetak
Monthly and seasonal extreme weather conditions in Croatia during the fire season from April to October for the period 2001 -2015 have been analyzed. Canadian Forest Fire Weather Index System (CFFWIS) for fire risk assessment is applied to estimate the mean value of Monthly and Seasonal Severity Rating (MSR and SSR). The Canadian method is used operationally in Meteorological and Hydrological Service of Croatia during the last 35 years. Spatial distribution of the MSR and SSR in Croatia for each year in the period 2001-2015 and their ratio with the long term averages 1981-2010 are presented. Forest fires are directly associated with drought and high air temperature. Therefore, drought periods regarding the type of fuel materials and periods of 10 and more consecutive days with maximum air temperature above 30°C and 32°C for 41 meteorological stations in Croatia have been also analyzed. Compared with the long term average 1981-2010 the most extreme SSR in the 21st century was in 2003 and 2012. This was due to an extreme weather conditions that prevailed during these years. For instance, three heat waves occurred in 2012 with maximum air temperature above 30°C at least 10 consecutive days on 21 stations. The longest lasted 39 days and the one with daily maximum temperature above 32°C lasted 18 consecutive days, both on stations situated in the mid-Adriatic. This region was found to be the most vulnerable in the 21st century, especially its islands and hinterland. Almost every year the high air temperature was followed by a drought period. In 2012 in the mid-Adriatic lasted from the middle of June until the middle of September. Analysis of MSR and SSR in this century showed that high fire risk is not only spreading towards the northern Adriatic, but also to the inland, especially to eastern continental part of Croatia which is the most important agricultural area. According to climate projections for the rest of the 21st century, it is likely to expect more severe fire season in the future.
