%X Stochastic sand trajectories in wind-blown sand were obtained by solving the differential equation which describes the vertical fluctuating velocity of sand grains.The results show that because of the effect of account of vertical fluctuating velocity,the trajectories of sand grain involving the effect are differ obviously from that not involving the effect.And then,the concentration profiles were presented based on statistical analysis of ensemble of such stochastic trajectories.
