The physics of snow crystals [PDF]

open access: yesReports on Progress in Physics, 2005
We examine the physical mechanisms governing the formation of snow crystals, treating this problem as a case study of the dynamics of crystal growth from the vapour phase.

Snow physics as relevant to snow photochemistry [PDF]

open access: yesAtmospheric Chemistry and Physics, 2008
Snow on the ground is a complex multiphase photochemical reactor that dramatically modifies the chemical composition of the overlying atmosphere. A quantitative description of the emissions of reactive gases by snow requires knowledge of snow physical ...

Improving the snow physics of WEB-DHM and its point evaluation at the SnowMIP sites [PDF]

open access: yesHydrology and Earth System Sciences, 2010
In this study, the snow physics of a distributed biosphere hydrological model, referred to as the Water and Energy Budget based Distributed Hydrological Model (WEB-DHM) is significantly improved by incorporating the three-layer physically based energy ...

Boundary layer physics over snow and ice [PDF]

open access: yesAtmospheric Chemistry and Physics, 2007
Observations of the unique chemical environment over snow and ice in recent decades, particularly in the polar regions. have stimulated increasing interest in the boundary layer processes that mediate exchanges between the ice/snow interface and the ...

Reflections on the anomalous ANITA events: the Antarctic subsurface as a possible explanation

open access: yesAnnals of Glaciology, 2020
The Antarctic Impulsive Transient Antenna (ANITA) balloon experiment was designed to detect radio signals initiated by high-energy neutrinos and cosmic ray (CR) air showers.

A casting method using contrast-enhanced diethylphthalate for micro-computed tomography of snow

open access: yesJournal of Glaciology, 2021
Casting snow is necessary to prevent metamorphism and deformation prior to X-ray micro-computed tomography (μCT) imaging. Current methods are insufficient for large-scale field sampling of snow due to safety considerations associated with the casting ...

Disentangling creep and isothermal metamorphism during snow settlement with X-ray tomography

open access: yesJournal of Glaciology, 2023
Once fallen, snow settles due to the combined effects of metamorphism and deformation of the ice matrix under gravity. To understand how these coupled processes affect snow evolution, we performed oedometric compression tests and continuously monitored ...

The Snow-Friction of Freestyle Skis and Snowboards Predicted From Snow Physical Quantities [PDF]

open access: yesFrontiers in Mechanical Engineering, 2021
Previous research has shown that friction between ski and snow can vary substantially due to changes in snow conditions. The variation of friction affects the speed a freestyle skier or snowboarder (athlete) reaches during the in-run of a jump. Athletes risk severe injuries if their take-off speed is not within the right margin to land in the “sweet ...

Porosity dependence of elastic moduli of snow and firn

open access: yesJournal of Glaciology, 2021
Measurements of elastic wave velocities enable non-destructive estimation of the mechanical properties, elastic moduli and density of snow and firn.

Multi-physics ensemble snow modelling in the western Himalaya [PDF]

open access: yes, 2020
Combining multiple data sources with multi-physics simulation frameworks offers new potential to extend snow model inter-comparison efforts to the Himalaya.
