Furthermore, the definitions of the danger levels, an ordinal variable,…

On snow stability interpretation of extended column test results

10. Juli 2020

2020 Frank Techel, Kurt Winkler, Matthias Walcher, Alec van Herwijnen, and Jürg Schweizer Nat. Hazards Earth Syst. Sci., 20, 1941–1953, 2020 https://doi.org/10.5194/nhess-20-1941-2020 Abstract Snow instability tests provide valuable information regarding the stability of the snowpack. Test results are key data used to prepare public avalanche forecasts. However, to include them into operational procedures, a quantitative interpretation scheme is needed. Whereas…

On the relation between avalanche occurrence and avalanche danger level

2. März 2020

2020 Jürg Schweizer, Christoph Mitterer, Frank Techel, Andreas Stoffel, and Benjamin Reuter The Cryosphere, 14, 737–750, 2020 https://doi.org/10.5194/tc-14-737-2020 Abstract In many countries with seasonally snow-covered mountain ranges warnings are issued to alert the public about imminent avalanche danger, mostly employing an ordinal, five-level danger scale. However, as avalanche danger cannot be measured, the characterization of avalanche danger…

Describing Snow Instability by Failure Initiation,Crack Propagation, and Slab Tensile Support

26. Juli 2018

2018 Ben Reuter, Jürg Schweizer Geophysical Research Letters, 45, 7019–7027. https://doi.org/10.1029/2018GL078069 Abstract Snow instability is a generic term describing the propensity of a snow slope to avalanche. Inneed of a concise mechanics-based concept we suggest a framework based on failure initiation, crackpropagation, and slab tensile support. Following these three steps we modeled three metrics frommechanical data, which we…
