Wind Tunnel Experiments: Influence of Erosion and Deposition on Wind-Packing of New Snow
Wind sometimes creates a hard, wind-packed layer at the surface of a snowpack. The formation of such wind crusts was observed during wind tunnel experiments with combined SnowMicroPen and Microsoft Kinect sensors. The former provides the hardness of new and wind-packed snow and the latter spatial snow depth data in the test section. Previous experiments had shown that saltation is necessary but...
متن کاملModeling and Validation of Snow Redistribution by Wind
As part of the effort of the Centre d'Etudes de la Neige Météo-France (Snow Research Centre), for the improvement in modeling snow cover evolution and avalanche hazard forecasting, a numerical simulation of snow transport by the wind has been developed over the last years. This application is based on field measurements at a high altitude experimental site (2700 m) that leads: • Firstly, to imp...
متن کاملLattice Gas Modeling of Snow Transport by Wind
We present a lattice gas model to simulate snow transport by wind and its deposition on a given ground proole. Our approach is very well suited to a ne grained massively parallel computing.

متن کاملOn the saltation of fresh snow in a wind tunnel: Profile characterization and single particle statistics
[1] We present experimental results on the snow drift in a turbulent boundary layer over a flat fresh snow-covered surface. Vertical profiles of mass flux and of the distribution of particle diameters were obtained by means of a pair of Snow Particle Counters parallel with measurements of the stream-wise velocity profile. The aim of the paper is to discuss current parameterizations of the verti...
