Some features of heat waves in Croatia

Rad se bavi nekim obilježjima toplinskih valova na području Hrvatske. Provedena je analiza intenziteta, trajanja te učestalosti toplinskih valova. Analiza je provedena na devet meteoroloških postaja na području Hrvatske (Osijek, Daruvar, Varaždin, Zagreb, Ogulin, Pula, Knin, Split i Dubrovnik) u četrdesetogodišnjem razdoblju od 1980. do 2019. godine. Kako bi se utvrdila promjena ukupnog trajanja i intenziteta toplinskih valova u istraživanom razdoblju određeni su linearni trendovi, a promjena je analizirana u dva dvadesetogodišnja perioda (1980. – 1999. i 2000. – 2019.). Rezultati analize pokazuju trend porasta intenziteta, trajanja i učestalosti toplinskih valova u većini analiziranih postaja.The paper deals with some features of heat waves in Croatia. An analysis of the intensity, duration and frequency of heat waves was performed. The analysis was conducted at nine meteorological stations in Croatia (Osijek, Daruvar, Varaždin, Zagreb, Ogulin, Pula, Knin, Split and Dubrovnik) in the forty-year period from 1980 to 2019. In order to determine the change in the total duration and intensity of heat waves in the studied period, linear trends were determined, and the change was analyzed in two twenty-year periods (1980 – 1999 and 2000 – 2019). The results of the analysis show a trend of increasing intensity, duration and frequency of heat waves in most of the analyzed stations
