| Abstract: | Coupled equations of motion of wind and snow particles for steady state saltation are presented and solved for a simplified grain surface impact process.The results show that saltating snow particles have important effects on wind velocities near surface and Magnus lifting force also has effects on the wind profiles as well as saltating trajectories of snow particles. |
