The mountain frost hollows show severe temperature conditions with increased amplitudes, especially due to their pronounced minimum values. After 2004, the research of frost hollows in Slovenia received a new impetus, and the previous research, which was mainly focused on vegetation growth conditions, was extended to the field of climatology. Continuous measurements in several frost hollows conducted by researchers from the Slovenian Meteorological Forum resulted in an extensive amount of data and findings on temperature conditions in frost hollows, which we present in more detail in this paper. In addition to the new lowest temperatures measured in Slovenia, it turned out that the annual average temperatures in mountain frost hollows are up to 3 °C lower than in the surrounding area, and the average low temperatures are up to 7 °C. In recent decades, temperatures below -30 °C in Slovenia occurred exclusively in frost hollows, and at altitudes of 1000 and 1500 m this also applies to temperatures below -20 °C. The maximum temperatures in frost hollows are very similar to those outside, they can even be slightly higherRaznoliko površje gorskih pokrajin omogoča pestro topoklimo in velike gradiente meteoroloških in klimatoloških elementov, med katere uvrščamo tudi temperaturo zraka. Mrazišča gorskega sveta kažejo zaostrene temperaturne razmere s povečanimi amplitudami, zlasti zaradi izstopajočih najnižjih temperatur. Po letu 2004 je raziskovanje mrazišč v Sloveniji dobilo nov zagon, pretekle raziskave, ki so bile osredotočene zlasti na rastne pogoje, so dobile nadgradnjo na klimatološkem področju. Neprekinjene meritve v več mraziščih, ki so jih izvajali različni raziskovalci v okviru Slovenskega meteorološkega foruma, so privedle do obsežne količine podatkov in spoznanj o temperaturnih razmerah v mraziščih, ki jih podrobneje predstavljamo v tem prispevku. Poleg novih najnižjih izmerjenih temperatur v Sloveniji se je izkazalo, da so, glede na neposredno okolico, letne povprečne temperature sredogorskih mrazišč nižje do 3 °C, povprečne najnižje pa do 7 °C. Temperature pod -30 °C se v Sloveniji v zadnjih desetletjih pojavljajo izključno v mraziščih, v sredogorju to velja tudi za temperature pod -20 °C. Najvišje temperature v mraziščih pa so zelo podobne tistim izven njih, lahko so celo nekoliko višjeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Filozofska fakulteta
