Abstract: The invention relates to a passive snow removal system which deliberately rms vortices from a passing airflow and directs the vortices into scouring contact with snow accumulation on a target surface. The apparatus includes a base and a vortex producing plate rotatably mounted at an inclined angle relative to an upper portion of the base near the plate's center of mass. The geometry of the plate, which is preferably triangular, is used to aerodynamically form vortices from a passing airflow and direct the vortices onto a target surface. Once the vortices are in scouring contact with the target surface, they act upon the surface to dislodge and carry away any accumulated snow in the direction of the airflow and redeposit it downwind, thus removing the snow from the target surface.
