Avalanche danger level characteristics from field observations of snow instability

2021 Jürg Schweizer, Christoph Mitterer, Benjamin Reuter, and Frank Techel The Cryosphere, 15, 3293–3315, 2021   Abstract Avalanche danger levels are described in qualitative terms that mostly are not amenable to measurements or observations. However, estimating and improving forecast consistency and accuracy require descriptors that can be observed or measured. Therefore, we aim to characterize the avalanche danger levels…

ECT Test Update

2020 Frank Techel, Karl Birkeland, Doug Chabot, Jim Earl, Ivan Moner, and Rob Simenhois the avalanche review #39.1| winter 20/21 Summary Since its introduction in 2006, the Extended Column Test (ECT) has become one of the most popular tests to assess point snow instability. In 2009, two studies explored how ECT results correlated to observed instabilities, laying the foundation for…

On the importance of snowpack stability, the frequency distribution of snowpack stability, and avalanche size in assessing the avalanche danger level

2020 Frank Techel, Karsten Müller, and Jürg Schweizer The Cryosphere, 14, 3503–3521, 2020   Abstract Consistency in assigning an avalanche danger level when forecasting or locally assessing avalanche hazard is essential but challenging to achieve, as relevant information is often scarce and must be interpreted in light of uncertainties. Furthermore, the definitions of the danger levels, an ordinal variable,…
