Abstract

Recent papers showed a general decrease of winter precipitation in the last years on Italian Alps and particularly snowy precipitations, both in the Western Italian Alps and in the Eastern part. In the Dolomites snowfall decreased of 28% during the period 1988-2003, comparing with average precipitations in 30 years (1971-2000). In this paper it is carried out an analysis of seasonal snowfall in the Dolomites and first results of a regional climatic evolution using the adimensional index SAT (Standardized Anomaly Index) Tor 40 nivological stations on the Alps. Furthermore decreasing snow precipitations corresponds to a strong reduction of Dolomites' glaciers (-24% of the surface during the period 1980-2000).
