Abstract: A set of hypotheses concerning the development of snowdrifts on natural alpine terrain was transformed into a model predicting the location and extent of snowdrift accumulation. Windspeed and snowfall rate are the primary dynamic inputs to the model. Field measurements at two sites on Niwot Ridge in the Colorado Front Range were used to analyze the model. It appears to be sensitive to changes in the threshold windspeed for the initiation of grain deposition and the delimitation of the lower boundary of the atmospheric mixing region. Windspeed is the dominant determinant for accumulation rate; maximum accumulation rates occur at moderate windspeeds. The model must be validated before it can be used in an operational setting.
