The following five air temperatures indices (ATI) are analysed: (1) absolute minimum yearly, monthly, and daily; (2) mean yearly, monthly, and daily minimum; (3) average mean yearly, monthly, and daily; (4) mean yearly, monthly, and daily maximum; (5) absolute maximum yearly, monthly, and daily. Methods of Rescaled Adjusted Partial Sums (RAPS), regression and correlation analyses, F-tests, and t-tests are used in order to describe changes in air temperature regimes over 137 years. Using the RAPS method the five analysed yearly ATI time series durations of 137 years were divided into two sub-periods. The analyses made in this paper showed that warming of minimum air temperatures started in 1970, mean air temperatures in 1988, and maximum air temperatures in 1998. Results of t-tests show an extreme statistically significant jump in the average air-temperature values in the second (recent time) sub-periods. Results of the t-tests of monthly temperatures show statistically significant differences between practically all five pairs (except in two cases) of analysed monthly ATI subseries for the period from January to August. From September to December the differences for most of pairs (except in six cases) of the analysed monthly ATI subseries are not statistically significant. It can be concluded that the urban heat island influenced the increase in recent temperatures more strongly than global warming. It seems that urbanisation firstly and chiefly influenced the minimum temperatures, as well as that Zagrebs urbanisation had a bigger impact on minimum temperatures than on maximums. Increasing trend in time series of maximum temperatures started 20 years later"},{"@xml:lang":"sl","#text":"Članek obravnava časovne vrste značilnih (minimalnih, srednjih in maksimalnih) dnevnih, mesečnih in letnih temperatur zraka, izmerjenih v Observatoriju Zagreb Grič v obdobju od 1. 1. 1881 do 31. 12. 2017. Analizirali smo pet indeksov temperature zraka: (1) absolutni minimalni letni, mesečni in dnevni; (2) srednji letni, mesečni in dnevni minimalni; (3) povprečni srednji letni, mesečni in dnevni; (4) srednji letni, mesečni in dnevni maksimalni; (5) absolutni letni, mesečni in dnevni. Za opis sprememb režimov letnih temperatur v obdobju 137 let smo uporabili metodo umerjenih delnih vsot (Rescaled Adjusted Partial Sums RAPS), regresijsko in korelacijsko analizo, F-test in t-test. Pri uporabi metode umerjenih delnih vsot (RAPS) smo pet analiziranih letnih časovnih vrst indeksa temperature zraka v obdobju 137 let razdelili v dve podobdobji. Analize, opravljene za potrebe tega prispevka, so pokazale, da so minimalne temperature zraka začele naraščati leta 1970, srednje temperature zraka leta 1988 in maksimalne temperature zraka leta 1998. Rezultati t-testov kažejo ekstremno statistično značilno povečanje povprečnih vrednosti temperature zraka v drugem (zadnjem) podobdobju. Rezultati t-testov mesečnih temperatur izkazujejo statistično značilne razlike med praktično vsemi petimi pari (razen v dveh primerih) analiziranih mesečnih podserij indeksov temperature zraka za obdobje od januarja do avgusta. Od septembra do decembra razlike pri večini parov (razen v šestih primerih) analiziranih mesečnih podserij indeksov temperature zraka niso statistično značilne. Zaključimo lahko, da je bil vpliv mestnega toplotnega otoka na naraščanje temperatur v zadnjem času večji kot vpliv globalnega segrevanja. Zdi se, da je urbanizacija vplivala najprej in predvsem na minimalne temperature in da je bil vpliv urbanizacije v Zagrebu večji na minimalne kot na maksimalne temperature. Trend naraščanja v časovnih vrstah maksimalnih temperatur se je začel 20 let pozneje"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-OGQVNDJU","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-OGQVNDJU"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-OGQVNDJU/83766f49-f31c-465b-8917-0e4a4e9c5396/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by-nc-sa/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za gradbeništvo in geodezijo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-OGQVNDJU/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-OGQVNDJU"}}}}
