Excerpt from Numerical Simulation of Jet Roof Geometry for Snow Cornice Control In many areas, snow cornices and the snow cushion that often forms downslope from them present serious safety problems. Snow avalanches triggered by falling cornice blocks or by failure in the snow cushion are common on such Slopes. Strategic placement of a simple wind deflector, called a jet roof, at the ridge crest Will often alleviate the pro blem by deflecting the wind down the lee slope and preventing or reducing the formation of the cornice and changing the snow deposition pattern on the slope. This paper gives information regarding the location and shape of such structures based on a computer program modeling of wind flow patterns over the ridge.
