The present study was to develop a new snow fence with the airfoil snow plates for the prevention of blowing-snow disasters. In the previous report, it was found that the developed new type snow fence with the airfoil snow plates had a high performance in preventing snowdrifts and improving visibility in comparison with the conventional snow fence. In this report, the characteristics of aerodynamic fluid forces and the flow-induced vibrations of the airfoil snow plates was investigated. Important results from the present study were that (i) the fluctuating fluid forces acting on the airfoil snow plates which set up the topmost part of the snow fence was the most values in all of them, (ii) the flow-induced vibrations in the airfoil snow plate attached on the topmost part was generated, and then become divergent, (iii) the fluctuating fluid forces and the flow-induced vibrations of the airfoil snow plate were completely suppressed when a perforated plate was attached at the top part of the snow fence.
