Abstract: So as to study snowdrift at short time scales on an experimental field located in l’Alpe d’Huez, France, at an elevation of 2700 meters, mass flux and wind speed were simultaneously recorded at short time rates. The devices able to process such measurements in so hard meteorological conditions are driftometer for transport rate and sonic anemometer for wind vector. Few models of acoustic driftometers are now available but performances of two sensors will be compared on the basis of a complete recording performed during winter 2003-2004. Influence of snow grains types seems to play a significant role in the data sets. Results of specific tests realised in a biphasic wind-tunnel are delivered in this paper with the aim to checking this parameter.
