Snow transport in extreme environments: from small to large scale modeling

The cold regions on Earth, such as the polar and high mountain regions, are snow covered for at least a part of the year. These snow-covered surfaces are highly dynamic, particularly under the influence of strong winds. The aeolian or wind-driven transport ...

Towards a fully physical representation of snow on Arctic sea ice using a 3D snow-atmosphere model

Michael Lehning, Adrien Michel, Océane Hames, Nander Wever, Marc Schneebeli Zeugin, David Nicholas Wagner, Mahdi Jafari

In high elevation Alpine areas, characterised by high snow accumulation and radiation-driven melt processes, the formation of peculiar ablation features called sun cups can be observed. Sun cups likely influence the energy and mass balance of the wet snowp ...

Temporal Prediction of Landslide-Generated Waves Using a Theoretical-Statistical Combined Method

Christophe Ancey, Zhenzhu Meng, Yating Hu

For the prediction of landslide-generated waves, previous studies have developed numerous empirical equations to express the maximums of wave characteristics as functions of slide parameters upon impact. In this study, we built the temporal relationship be ...

Characterizing airborne snow metamorphism using stable water isotope measurements in snow and vapor from ring wind tunnel experiments

Michael Lehning, Sonja Wahl, Luca Bianchi, Benjamin Andreas Walter

Drifting-blowing snow events are frequent phenomena in alpine and polar regions with direct effects on the local mass and energy balance that are difficult to quantify. In addition to this immediate impact of the blowing snow cloud the aeolian transport mo ...

Spatio-Temporal Dynamics of Snow on Central Arctic Sea Ice and its Implications

David Nicholas Wagner

This thesis presents a comprehensive investigation of the interaction between precipitation and wind-induced erosion and deposition of snow on Arctic sea ice. The study uses observations from the 2019-2020 MOSAiC expedition and makes use of the 3D snow cov ...

Towards continuous measurements of snow drift and sublimation in polar environments

Michael Lehning, Wolf Hendrik Huwald, John Martin Kolinski, Armin Sigmund, Yael Frischholz, Balthazar Allegri

In polar regions, and specifically in continental Antarctica, the local surface mass and energy balances can be largely controlled by snow transport in form of drifting and blowing snow particles, and sublimation both from the snow or ice surface and from ...

Temporal Prediction of Landslide-GeneratedWaves Using a Theoretical–Statistical Combined Method.

Christophe Ancey, Zhenzhu Meng, Yating Hu

For the prediction of landslide-generated waves, previous studies have developed numerous empirical equations to express the maximums of wave characteristics as functions of slide parameters upon impact. In this study, we built the temporal relationship be ...

Numerical investigation of the effect of cohesion and ground friction on snow avalanches flow regimes

Johan Alexandre Philippe Gaume, Betty Sovilla

With ongoing global warming, snow avalanche dynamics may change as snow cohesion and friction strongly depend on temperature. In the field, a diversity of avalanche flow regimes has been reported including fast, sheared flows and slow plugs. While the sign ...

Transition from sub-Rayleigh anticrack to supershear crack propagation in snow avalanches

Johan Alexandre Philippe Gaume, Bertil Trottet, Grégoire Bobillier, Alec van Herwijnen

Avalanches can occur when a porous snow layer lies beneath a dense cohesive snow slab. Field experiments and simulations now reveal different crack-propagation regimes in slab avalanches, similar to rupture propagation following an earthquake. Snow slab av ...

Detrainment and braking of snow avalanches interacting with forests

Johan Alexandre Philippe Gaume, Xingyue Li, Louis Jean Henri Vedrine

Mountain forests provide natural protection against avalanches. They can both prevent avalanche formation in release zones and reduce avalanche mobility in runout areas. Although the braking effect of forests has been previously explored through global sta ...
