Antarctic Snow Failure Mechanics: Analysis, Simulations, and Applications [PDF]
MaterialsSnow failure is the process by which the stability of snow or snow-covered slopes is destroyed, resulting in the collapse or release of snow. Heavy snowfall, low temperatures, and volatile weather typically cause consequences in Antarctica, which can ...

Snow mechanical property variability at the slope scale – implication for snow mechanical modelling
The Cryosphere, 2023 Abstract. Snow avalanches represent a natural hazard to infrastructure and backcountry recreationists. Risk assessment of avalanche hazard is difficult due to the sparse nature of available observations informing on snowpack mechanical and geophysical properties and overall stability.

Detrainment and braking of snow avalanches interacting with forests [PDF]
Natural Hazards and Earth System Sciences, 2022 Mountain forests provide natural protection against avalanches. They can both prevent avalanche formation in release zones and reduce avalanche mobility in runout areas.

Heterogeneous grain growth and vertical mass transfer within a snow layer under a temperature gradient [PDF]
The Cryosphere, 2023 Inside a snow cover, metamorphism plays a key role in snow evolution at different scales. This study focuses on the impact of temperature gradient metamorphism on a snow layer in its vertical extent.

Intercomparison of snow density measurements: bias, precision, and vertical resolution [PDF]
, 2016 Density is a fundamental property of porous media such as snow. A wide range of snow properties and physical processes are linked to density, but few studies have addressed the uncertainty in snow density measurements.

Snow-Collection Mechanisms and the Capacities of Snow Fences [PDF]
Annals of Glaciology, 1989 The shapes of equilibrium lee drifts formed by snow fences are scaled in proportion to height of snow fences independent of the snow and weather conditions, even in small-scale models, but those of up-wind drifts are not.Field studies have been made of the snow-collection mechanisms of a snow fence.

Journal of Glaciology, 2018 The critique by Issler and other (2017) of our avalanche dynamics model maintains that we disregard well-established results of particulate gravity flows.

The mechanism of sliding on ice and snow [PDF]
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1939 Abstract The preceding paper has shown that the sliding friction bet ween metals decreases in a regular manner as the temperature is raised, provided that the chemical nature of the surface layers remains unchanged. The behaviour of the friction at temperatures near the melting-point was not investigated.

Wind conditions for snow cornice formation in a wind tunnel [PDF]
The Cryosphere, 2023 Snow cornices growing on the leeward side of mountain ridges are common in alpine and polar regions during snow seasons. These structures may crack and fall, leading to an increase in avalanche danger. Although cornice formation has been observed in wind
