地吹雪臨界風速のパラメ-タ化

概要

論文の詳細を見る
The wind speed at the surface of snow cover was parameterized as functions of the density of snow cover and the size of snow particles. The critical wind speed to cause drifting snow decreases with decreasing density of snow cover and size of snow particles. This means that fresh snow conditions are easy to occur drifting snow.<BR>A method was explained for estimating surface wind speed over a complex terrain with an inhomogeneous aerodynamic roughness.
