Latent cooling of atmosphere as an indicator of lowered snow line : Case study from Planica and Vrata valleys

Strle, Danijela (author), Ogrin, Matej (author)

A lowered snow line in Alpine valleys as a local weather phenomenon often varies from onevalley to another. The relief morphology of the valleys and the intensity of precipitation play a crucial rolein the variation. In Slovenia certain valleys are more susceptible to this phenomenon than others, one suchexample being the Planica Valley. This paper examines the occurrence of a lowered snow line in the PlanicaValley and the Vrata Valley during the winter seasons of 2015/2016 and 2016/2017. Precipitation eventsaccompanying the occurrence of a lowered snow line were analyzed, and data on temperature and pre-cipitation were included in the analysis. Results showed a striking degree of congruence of the phenomenonin both valleys.

Abstract

Znižana meja sneženja se, kot lokalni vremenski pojav, v alpskih dolinah ne pojavlja pov-sod v enaki meri. Ključno vlogo imata zaprtost dolinskega reliefa ter intenziteta padavin. Splošno znanov Sloveniji je, da so nekatere doline, kot na primer dolina Planice za ta pojav zelo dovzetne, druge pa manj.V nekaterih dolinah je pojav manj poznan zgolj zaradi tega, ker so neposeljene in pozimi tudi neoblju-dene. Prispevek govori o analizi pojava znižane meje sneženja v dolini Planice in dolini Vrata v dveh zimskihsezonah 2015/2016 in 2016/2017. Analizirani so bili padavinski dogodki s pojavom znižane meje sneženja,v analizo pa smo vključili temperaturne podatke ter podatke o padavinah. Rezultati so pokazali presenetljivoujemanje pojava v obeh dolinah.
