    Abstract: Wind-transported snow is a common phenomenon in mountainous and polar regions. Wind erodes snow from high wind speed areas and deposits it in low wind speed areas, thereby forming snowdrifts, cornices and wind slabs which may contribute significantly to avalanche releases. In this context, numerical simulation of drifting snow appears as a potential tool to support avalanche hazard forecasting. Part of the deposited snow is transported in the suspension layer and models simulate the vertical profile of blowing snow density in this layer. Our study focuses on the time evolution of this vertical profile during blowing snow events in order to detect the change in the snow particles shape during blowing snow events.
