The model can calculate each particle trajectory over a flat and uniform snow, under a steady wind with turbulence, modeled by a random-flight model. Hence, unlike another numerical methods, the transition process between saltation and suspension can be strictly treated in the model. In the calculation of particle eddy diffusivity, the calculated effective settling velocity and concentration for particles has been fitted with the power law given by the standard turbulent diffusion theory. The estimated eddy diffusivity for the particles shows a significant decrease from the eddy viscosity, particularly at high positions (～10m).}, pages = {33--39}, title = {吹雪浮遊層における雪粒子の乱流拡散係数 (小林俊一教授退官記念号）}, volume = {25}, year = {2003} }
