estimating the distribution of snow melt equivalent at the peak of snow accumulation, through degree – day model

estimating snow melt water equivalent is one of the most important challenges in determining the hydrological regime in mountainous basins. there are some problematic obstacles in field observations, due to inaccessibility as well due to difficulties in snow sampling at snow covered peaks making researchers try to find indirect approaches. one of these methods in use is degree- day model that i...

Occlusion-Based Snow Accumulation Simulation

We present a fast technique for the simulation of accumulated snow. Our technique is based on two phenomena; local occlusion of small holes and ditches, and the global influence of a skylight. We use ambient occlusion to predict the shape and location of snow accumulation and direct illumination from the skylight to simulate the melting and sublimation of snow as dissipation. The snow is simula...

Analysis of the snow-atmosphere energy balance during wet-snow instabilities and implications for avalanche prediction

Wet-snow avalanches are notoriously difficult to predict; their formation mechanism is poorly understood since in situ measurements representing the thermal and mechanical evolution are difficult to perform. Instead, air temperature is commonly used as a predictor variable for days with high wet-snow avalanche danger – often with limited success. As melt water is a major driver of wet-snow inst...
