Temporospatial variability of snow's thermal conductivity on Arctic sea ice [PDF]
The Cryosphere, 2023 Snow significantly impacts the seasonal growth of Arctic sea ice due to its thermally insulating properties. Various measurements and parameterizations of thermal properties exist, but an assessment of the entire seasonal evolution of thermal ...

Fractional snow-covered area parameterization over complex topography [PDF]
Hydrology and Earth System Sciences, 2015 Fractional snow-covered area (SCA) is a key parameter in large-scale hydrological, meteorological and regional climate models. Since SCA affects albedos and surface energy balance fluxes, it is especially of interest over mountainous terrain where ...

How much can we save? Impact of different emission scenarios on future snow cover in the Alps [PDF]
The Cryosphere, 2017 This study focuses on an assessment of the future snow depth for two larger Alpine catchments. Automatic weather station data from two diverse regions in the Swiss Alps have been used as input for the Alpine3D surface process model to compute the snow ...

Perspectives on Snow Avalanche Dynamics Research [PDF]
Geosciences, 2021 As an introduction for non-specialists to the Special Issue on snow avalanche dynamics, this paper first outlines how understanding the dynamics of snow avalanches can contribute to reducing risk for settlements and infrastructure. The main knowledge gaps in this field of research concern (i) the properties of the flow regimes and the transitions ...

Crack propagation speeds in weak snowpack layers
Journal of Glaciology, 2022 For the release of a slab avalanche, crack propagation within a weak snowpack layer below a cohesive snow slab is required. As crack speed measurements can give insight into underlying processes, we analysed three crack propagation events that occurred ...

Distributed snow and rock temperature modelling in steep rock walls using Alpine3D [PDF]
The Cryosphere, 2017 In this study we modelled the influence of the spatially and temporally heterogeneous snow cover on the surface energy balance and thus on rock temperatures in two rugged, steep rock walls on the Gemsstock ridge in the central Swiss Alps.

Influence of stress, temperature and crystal morphology on isothermal densification and specific surface area decrease of new snow [PDF]
The Cryosphere, 2014 Laboratory-based, experimental data for the microstructural evolution of new snow are scarce, though applications would benefit from a quantitative characterization of the main influences.

Automated snow avalanche release area delineation – validation of existing algorithms and proposition of a new object-based approach for large-scale hazard indication mapping [PDF]
Natural Hazards and Earth System Sciences, 2018 Snow avalanche hazard is threatening people and infrastructure in all alpine regions with seasonal or permanent snow cover around the globe. Coping with this hazard is a big challenge and during the past centuries, different strategies were developed.
