Calculation of Wind profiles and Numerical Simulation of Snow Particle Motions Using k-ƒÃ Turbulence Model

Yusuke HUKUSHIMA

The simulation of snow particles motions is carried out based on the k-ƒÃ turbulence model. The motions of snow particles in air are divided into three, i.e. the surface creep, the saltation and the suspension. The splash process which determines the impact and the ejection of snow particles on the snow surface is introduced in the simulation model. The values of the density of particles are estimated in the two-dimensional simulation. The calculated distribution of snow particles in the vertical direction is compared with the field observational results at the Mizuho station in Antarctica.
