Favorable Conditions for Avalanche Triggering During 2018-2019 Winter

Abstract

The paper presents and analyzes the variations of the meteorological and specific snow parameters, which favored avalanches occurence during 2018-2019 winter, in the area monitored by the National Administration of Meteorology. The analyzed parameters are measured by daily observations and weekly measurements at the weather stations Bâlea-Lac, Omu Peak, Sinaia and Predeal, Parâng, Țarcu, Semenic, Vlădeasa, Iezer, Călimani, Ceahlău, in order to use them for a better avalanche risk estimation and the diminution of their effects on the environment and people. The favorable conditions for triggering the avalanches were due to the significant snowfall, high temperature values or their sudden increase, as well as the transformations that take place inside the snow layer, when unstable structures are formed.
