Abstract: Over the last three winter seasons four laboratories specialized on snow research have joined their know how to better understand the mechanism of wind-transported snow in a project appropriately named «Snow and Wind». In this project several methods for studying the wind's effect on snow are investigated. In this paper, we will overview essentially the research conducted on: -the different wind-speed thresholds allowing drift in connection with snow grain types and snow cover surface and the characteristics of the blowing snow. -the spatial snow distribution using photogrammetric techniques. The group of laboratories have also investigated the: visualization of particles in movement and properties of snow reflectivity.
