Lac Blanc Pass: a natural wind-tunnel for studying drifting snow at 2700ma.s.l
ABSTRACT: The investigation of the spatial variability of snow depth in high alpine areas is an impor-tant topic in snow hydrology, glacier and avalanche research and the transport of snow by wind is an important process for the distribution of snow in mountainous regions. That's why, for 25 ye...
