• A new snow fence with airfoil snow plates was developed to prevent blowing-snow disasters. In a previous report, we showed that in comparison with the conventional snow fence, this snow fence with airfoil snow plates performed very well in preventing snowdrifts and in improving visibility. The characteristics of the aerodynamic fluid forces on and flow-induced vibrations of the airfoil snow plates now have been investigated. The important findings are (i) fluctuating fluid forces acting on the airfoil snow plate set at the topmost part of the snow fence are the most serious, (ii) flow-induced vibrations generated in the airfoil snow plate attached to the topmost part of the snow fence are rapidly amplified by an increase in wind velocity, (iii) the fluctuating fluid forces on and flow-induced vibrations in the airfoil snow plates could be completely suppressed when a perforated plate was attached to the topmost part of the snow fence.
