Deposition and erosion of snow by the wind

摘要: Abstract : The theories of uniform and non-uniform drifting snow are summarized with special emphasis on drift transport as a function wind velocity. It is confirmed that the process involves mobile surface layer saltating particles, self-regulating thickness depending only stress not concentration in free air stream. shown to be characteristic (in contrast sand or silt) saltation suspension occur side by latter reaches predominance velocity rises through most common range values. Theoretical reasons observational evidence produced for view deposition erosion occurs during primarily result mass flux convergence divergence (Author)
