What weather variables are important for wet and slab avalanches under a changing climate in a low-altitude mountain range in Czechia?
Original language description
Climate change impact on avalanches is ambiguous. Fewer, wetter, and smaller avalanches are expected in areas where snow cover is declining, while in higher altitude areas where snowfall prevails, snow avalanches are frequently and spontaneously triggered. In the present paper, we (1) analyse trends in frequency, magnitude, and orientation of wet and slab avalanche activity during 59 winter seasons (1962 2021) and (2) detect the main meteorological and snow drivers of wet and slab avalanches for winter seasons from 1979 to 2020 using machine learning techniques decision trees and random forest with a tool that can balance the avalanche day and non avalanche day dataset. In terms of avalanches, low to medium high mountain ranges are neglected in the literature. Therefore we focused on the low altitude Czech Krkonoše mountain range (Central Europe). The analysis is based on an avalanche dataset of 60 avalanche paths. The number and size of wet avalanches in February and March have increased, which is
