Abstract

Critical avalanche conditions at a given site can be forecast by statistical analysis of snow and weather variables, during the ten previous years. From coarse measurements, one can determine explicative data. Using these variables, "critical avalanche weather" types can be defined. "Avalanche days" can be singled out from each weather type by linear and quadratic discriminant analysis. Application to data obtained on twelve winters for Davos (Swiss Alps). From this scheme, it has been possible to design and test an operational model covering the two following winters.
