Abstract:Delo obravnava vročinske valove na območju Pomurja v obdobju med letoma 1961 in 2018. Na podlagi podatkov meteoroloških postaj Rakičan, Jeruzalem, Lendava, Veliki Dolenci in Podgradje so analizirani trendi vročinskih valov v Pomurju. Vročinski valovi so obravnavani na podlagi povprečnih in maksimalnih temperatur zraka in vročih dni v Pomurju. V prvem delu so zato analizirane povprečne letne in poletne temperature zraka ter povprečne maksimalne letne in poletne temperature zraka v Pomurju. Sledi analiza števila vročih dni na letni, desetletni in mesečni ravni. V osrednjem delu naloge so analizirani vročinski valovi, in sicer število vročinskih valov; trajanje vročinskih valov, ki je analizirano na podlagi števila vročih dni v vročinskih valovih, povprečnega in maksimalnega trajanja vročinskih valov; intenzivnost vročinskih valov, ki je analizirana na podlagi maksimalnih temperatur zraka v vročinskih valovih in kumulativ maksimalnih temperatur zraka v vročinskih valovih; širjenje časovnega okna vročinskih valov in razvoj vremena v času vročinskih valov. V splošnem so v Pomurju vročinski valovi vedno bolj pogosti na letni in desetletni ravni, povečuje se število vročih dni znotraj vročinskega vala in zato se povečuje povprečno trajanje vročinskih valov. Iz desetletja v desetletje se povečuje maksimalna temperatura zraka vročinskih valov, kakor tudi kumulative maksimalnih temperatur, zato so vročinski valovi na obravnavanem območju vse intenzivnejši. V Pomurju vročinski valovi nastopajo v poletnih mesecih, a se časovno okno pojavljanja vročinskih valov širi, saj se pojavljajo vedno bolj zgodaj poleti ali pozno spomladi in vedno kasneje ob koncu poletja oz. na začetku jeseni. V glavnem so trendi vseh kazalnikov vročinskih valov v Pomurju pozitivni, prihaja pa do razlik med različnimi meteorološkimi postajami. Praviloma so višji trendi značilni za meteorološke postaje, ki se nahajajo v termalnem pasu in gosto pozidanih ter naseljenih območjih.

Title:Analysis of heat wave trends in Pomurje in the period 1961-2018
Abstract:The work addresses heat waves in Pomurje region in the period between 1961 and 2018. Based on information from Rakičan, Jeruzalem, Lendava and Veliki Dolenci meteorological stations, we have analysed the heat wave trends in Pomurje region. Heat waves are calculated based on average and maximum air temperature of hot days in Pomurje. In the first part of our thesis, we analysed average annual and summer air temperatures, as well as average maximum annual and summer air temperatures in Pomurje. Based on that, we carried out an analysis of the number of hot days on annual, ten-year and monthly basis. In the central part of the thesis, we analysed the heat waves – more precisely the number of heat waves; the duration of heat waves, which is analysed based on the number of hot days in specific heat wave, as well as average and maximum duration of heat waves; intensity of heat waves, which is analysed based on maximum air temperatures during heat waves and cumulative of maximum temperatures during heat waves; the expansion of the heat wave time window and the weather development during heat waves. In general, the heat waves in Pomurje region are more frequent on annual and ten-year basis and the number of hot days inside a heat wave is increasing, which is why the average duration of heat waves is also increasing. From one decade to another, the maximum air temperature of heat waves and cumulative of maximum temperatures is increasing, therefore, the heat waves in this analysed area are getting more and more intense. In Pomurje region, heat waves occur in summer months, but the heat wave time window is expanding, since the heat waves occur in early summer or in late spring and always by the end of summer or in early autumn. Mostly, all the indicator trends of heat waves in Pomurje are positive, but there are some variations among different meteorological stations. Higher trends are often significant for meteorological stations that are located in the thermal zone and densely built-up and populated areas.
