摘要:A lowered snow line in Alpine valleys as a local weather phenomenon often varies from one valley to another. The relief morphology of the valleys and the intensity of precipitation play a crucial role in the variation. In Slovenia certain valleys are more susceptible to this phenomenon than others, one such example being the Planica Valley. This article examines the occurrence of a lowered snow line in the Planica Valley and the Vrata Valley during the winter seasons of 2015/2016 and 2016/2017. Precipitation events accompanying the occurrence of a lowered snow line were analyzed, and data on temperature and precipitation were included in the analysis. Results showed a striking degree of congruence of the phenomenon in both valleys.
