FAVORABLE CONDITIONS FOR THE RELEASE OF AVALANCHES IN THE 2021-2022 WINTER SEASON – CASE STUDY
Udo RECKERTH, Narcisa MILIAN
ABSTRACT. Favorable Conditions for the Release of Avalanches in the 2021- 2022 Winter Season – Case Study. The paper presents and analyzes the synoptic and snow-meteorological conditions that were the basis for the triggering of avalanches in the winter season 2021-2022 from the mountain massifs monitored within the snow program. Data recorded at mountain weather stations with nivometric measurements were used, as well as ground and altitude maps from the GFS archive for the analysis of synoptic situations. The purpose of the presentation is to emphasize the importance of observations and nivometric measurements, as spatial and temporal density, for estimating the avalanche risk at the level of all mountain massifs. The study is part of a larger project, which aims to inventory the cases of avalanches known so far in our country and the favorable conditions for their triggering, to use them for a better estimation of the avalanche risk and the reduction of their effects have these on the environment and people. The meeting of favorable conditions for the triggering of avalanches was due both to heavy snowfalls, high thermal values or their sudden increase, as well as to the transformations that take place inside the snow layer, as a result of which unstable structures are formed.
