Snow metamorphism: a fractal approach

, 2010
Snow is a porous disordered medium consisting of air and three water phases: ice, vapour and liquid. The ice phase consists of an assemblage of grains, ice matrix, initially arranged over a random load bearing skeleton.

Global perspective of nitrate flux in ice cores [PDF]

, 1995
The relationships between the concentration and the flux of chemical species (Cl-, NO3 - , SO42-, Na +, K + , NH4 + , Mg 2+ , Ca 2+) versus snow accumulation rate were examined at GISP2 and 20D in Greenland, Mount Logan from the St.

Simulations of snow distribution and hydrology in a mountain basin [PDF]

, 1999
We applied a version of the Regional Hydro‐Ecologic Simulation System (RHESSys) that implements snow redistribution, elevation partitioning, and wind‐driven sublimation to Loch Vale Watershed (LVWS), an alpine‐subalpine Rocky Mountain catchment where ...

Trends in wintertime climate in the northeastern United States: 1965–2005 [PDF]

, 2008
Humans experience climate variability and climate change primarily through changes in weather at local and regional scales. One of the most effective means to track these changes is through detailed analysis of meteorological data.

Studies on Physical Properties of Snow Based on Multi Channel Microwave Radiometer [PDF]

, 1985
The analysis of the data observed over a snow field with a breadboard model of MSR (microwave scanning radiometer) to be installed in MOS-1 (Marine Observation Satellite-1) indicates that: (1) the influence of incident angle on brightness temperature is ...

A Two-Threshold Model for Scaling Laws of Non-Interacting Snow Avalanches

, 2004
The sizes of snow slab failure that trigger snow avalanches are power-law distributed. Such a power-law probability distribution function has also been proposed to characterize different landslide types.

Operational snow-hydrological modeling for Switzerland

Frontiers in Earth Science, 2023
The seasonal evolution of snow cover has significant impacts on the hydrological cycle and microclimate in mountainous regions. However, snow processes also play a crucial role in triggering alpine mass movements and flooding, posing risks to people and ...
