Development of a Large-Eddy Simulation based Lagrangian Snow Transport Model

Abstract

This study aimed to propose a drifting snow model combined with a large-eddy simulation for flow field and a lagrangian model to predict particle motion. Aerodynamic entrainment, rebound and splash process of snow particle on snow surface were included. Then, a priori simulation within a boundary layer under weak wind speed condition was conducted. The streaky regions of high drifting-snow-density were formed near the snow surface along with the streamwise direction.
