20.500.12556/RUL-105377 Tipizacija pojava znižane meje sneženja v izbranih dolinah Julijskih Alp Typification of lowered snow line phenomenon in selected valleys of Julian Alps Za pojav znižane meje sneženje velja, da meja sneženja v isti zračni masi, med območji, ki so si blizu, zelo variira in je lokalno pomaknjena precej nižje od napovedane. Dejavnikov in vremenskih situacij, ki lahko privedejo do pojava, je več, v magistrski nalogi pa so podrobneje predstavljeni zgolj pomembnejši. Glavnima dejavnikoma za nastanek znižane meje sneženja (intenziteta padavin in blokada vetra) je posvečena še dodatna pozornost, saj je njun doprinos k latentnemu ohlajanju največji. Na podlagi vremenskih situacij, ob katerih smo v proučevanih alpskih dolinah Julijskih Alp zabeležili pojav, je bila izdelana tipizacija pojava znižane meje sneženja. Vsi zabeleženi dogodki so z vidika vremenskih situacij razvrščeni v tri tipe pojava. Vsak tip je na posameznih primerih podrobneje predstavljen, osnova za to pa so dvoletne meritve temperature na šestnajstih (od decembra 2015 do konca aprila 2016) oziroma na sedemnajstih (od decembra 2016 do konca aprila 2017) lokacijah v dolini Planice, v Vratih, Zadnjici, Loški Koritnici, na pobočju Karavank (Peč–Tromeja) in gorskem sedlu Luknja. Meritve temperature so poleg osnove za tipizacijo omogočile tudi določitev dovzetnosti proučevanih dolin za pojav. A typical feature of the lowered snow line phenomenon is the significant fluctuation in the snow line within the same air mass and between closely located areas. In such cases, the snow line appears locally much lower than forecast. The present Master's thesis presents the many factors and weather conditions that can lead to the aforementioned phenomenon, the most important of which are the intensity of precipitation and blocking of the wind, as they contribute most to latent cooling. A typisation of the lowered snow line phenomenon is designed on the basis of the logged weather conditions at the time of the occurrence of the phenomenon in the Alpine valleys of the Julian Alps. All logged occurrences are classified into three distinct types of the phenomenon on the basis of the weather condition; each type is described in detail using individual occurrences as examples. Temperature measurements in a two-year period at sixteen (from December 2015 to end of April 2016) or seventeen (from December 2016 to end of April 2017) locations in the valleys of Planica, Vrata, Zadnjica, and Loška Koritnica, slopes of Karavanke–Peč (The Triple Border, slo. Tromeja), and Luknja Saddle constitute the basis for the detailed descriptions. The temperature measurements served not only as the basis for the typisation but also for determining the valleys’ suitability for studying the phenomenon.
