Snow particle motion in process of cornice formation [PDF]

open access: yesThe Cryosphere
Snow 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 ...

Influence of Microstructure on Mechanical Properties of Snow

open access: yesDefence 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 ...

Particle tracking in snow avalanches with in situ calibrated inertial measurement units

open access: yesAnnals of Glaciology
In 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]

open access: yesThe Cryosphere
Snow 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 ...

Testing the Strength of Buried Surface Hoar Weak Layers Under Combined Compression and Shear Loading

open access: yesGeophysical Research Letters
We 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.

Enhanced Tire–Snow Sinkage Modeling for Optimized Electric Vehicle Traction Control in Northern China Snow Conditions

open access: yesWorld Electric Vehicle Journal
The 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 ...

Transient wave activity in snow avalanches is controlled by entrainment and topography

open access: yesCommunications Earth & Environment
Waves are omnipresent in avalanches on Earth and other planets. The dynamic nature of waves makes them dangerous in geological hazards such as debris flows, turbidity currents, lava flows, and snow avalanches.

Laws of friction in snow mechanics

open access: yes, 1976
Laws of sliding and friction are of primary importance in the determination of pre-fracture conditions for slab avalanches as well as for practical considerations such as determining snow pressure loads on constructions built in mountainous terrain.

Snowmelt Onset and Caribou (Rangifer tarandus) Spring Migration

open access: yesRemote Sensing
Caribou (Rangifer tarandus) undergo exceptionally large, annual synchronized migrations of thousands of kilometers, triggered by their shared environmental stimuli. The proximate triggers of those migrations remain mysterious, though snow characteristics

Mechanical properties of artificial snow

open access: yes, 2013
Mechanical properties of snow have been a subject of research since the mid-20th century. Theresearch done is based on natural snow. During the last decades the winter business industryhas been growing and also the interest for constructing buildings and artwork of snow. Suchconstructions are generally built using artificial snow, i.e. snow produced by
