Snow particle motion in process of cornice formation [PDF]
The CryosphereSnow cornices are a common snow pattern in cold regions, and their fracture and collapse can easily trigger avalanches. Despite numerous observations and experimental simulations on their formation process, the microscopic mechanism of their initial ...

Micrometeorological and morphological observations of surface hoar dynamics on a mountain snow cover [PDF]
, 2010 The formation, growth, and destruction of surface hoar crystals is an important feature of mountain snow covers as buried surface hoar layers are a frequent weak layer leading to unstable snowpacks.

Possible erosion mechanisms in snow avalanches
Annals of Glaciology, 2004 AbstractSnow erosion and entrainment processes in avalanches are classified according to their mechanisms, the flow regimes in which they occur, and their spatial position within the avalanche. Simple, but process-specific, models are proposed for erosion by impacts, abrasion, plowing and blasting.

Particle tracking in snow avalanches with in situ calibrated inertial measurement units
Annals of GlaciologyIn the course of an artificially triggered avalanche, a particle tracking procedure is combined with supplementary measurements, including Global Navigation Satellite System (GNSS) positioning, terrestrial laser ...

Microstructure-based modelling of snow mechanics: experimental evaluation of the cone penetration test [PDF]
The CryosphereSnow is a complex porous material presenting a variety of microstructural patterns. This microstructure largely controls the mechanical properties of snow, although the relation between the micro and macro properties remains to be better understood ...

Influence of Microstructure on Mechanical Properties of Snow
Defence Science Journal, 1995 Snow, being composed of ice grains of varying shapes, sizes, orientations, etc., has been treated as a particulate material. The mechanical properties of snow have been described in terms of microstructural parameters. A set of variables, which characterise the microstructure of snow at the granular level, has been chosen and quantified following ...

Testing the Strength of Buried Surface Hoar Weak Layers Under Combined Compression and Shear Loading
Geophysical Research LettersWe experimentally determined the multiaxial strength of weak layers of buried surface hoar using displacement‐controlled tests under combined normal and shear loading on a custom testing machine.

World Electric Vehicle JournalThe interaction between tires and snow layer is fundamental for vehicle safety on snowy roads. Due to the instantaneous high torque output characteristics of electric vehicles, they are more prone to slipping when driving in snow, which exacerbates the ...
