- Povzetek: V raziskavi je obravnavano dolgoročno spreminjanje povprečne letne temperature zraka in meddnevne (Day-to-Day, DTD) temperaturne spremenljivosti na devetih klimatoloških postajah, ki predstavljajo tri različna okoljska območja: celinska urbana okolja, Istrski polotok in jadranske otoke. Namen raziskave je bil ovrednotiti prostorsko skladnost dolgoročnih sprememb temperature ter preučiti, v kolikšni meri lokalne okoljske značilnosti vplivajo na kratkoročno temperaturno spremenljivost. Povprečna letna temperatura zraka na vseh postajah kaže statistično značilno naraščanje in izjemno močne korelacije med postajami znotraj posameznega okoljskega območja, kar kaže na prevladujoči podnebni signal regionalnega merila. Po drugi strani pa je prostorska skladnost DTD-spremenljivosti bistveno manjša, dolgoročni trendi pa večinoma niso statistično značilni, kar odraža močnejši vpliv lokalnih podnebnih in okoljskih dejavnikov. Na urbanih postajah je DTD-spremenljivost kljub izrazitemu segrevanju razmeroma stabilna, medtem ko manjša urbana središča izkazujejo večjo spremenljivost. Na Istrskem polotoku so opazne izrazite razlike med obalnimi in celinskimi lokacijami, medtem ko jadranski otoki kljub skupnemu maritimnemu okolju izkazujejo izjemno homogene trende povprečne letne temperature zraka, vendar lokalno različne značilnosti DTD-spremenljivosti. Rezultati kažejo, da povprečna letna temperatura zraka predvsem odraža podnebne vplive regionalnega merila, medtem ko DTD-spremenljivost omogoča vpogled v lokalno podnebno stabilnost in kratkotrajne atmosferske procese. Raziskava dokazuje, da lahko analize, ki temeljijo izključno na povprečni letni temperaturi zraka, spregledajo pomembne vidike lokalne podnebne spremenljivosti, ter poudarja pomen DTD-spremenljivosti kot dopolnilnega kazalnika za razumevanje podnebnih sprememb v različnih okoljskih območjih.
