ANALYSE CLIMATIQUE DE L’ENNEIGEMENT ET EVALUATIONS DES EVENEMENTS EXTREMES SUR LES ALPES OCCIDENTALES D’ITALIE DANS LE CONTEXTE DU PROJET INTERREG STRADA

Snow climatological analysis and assessments of the extreme events in western Italian Alps in the context of the interreg project STRADA. In this study we will present the results of an activity of the strategic project STRADA (STRategies of ADAptation to climate change). This is the analysis of snow depth variations in the western Alps during the period 1925-2010. These series were available until now, only on paper: we performed the recovery and digitization of daily data. We carried out the historical research and data quality control which allowed a complete climate analysis, with the identification of trends and their statistical significance. The availability of daily series also allowed the application of advanced statistical techniques based on the Generalized Distribution of Extreme Events to assess the return period. The results will provide useful information to the prediction and adaptation of climate risks.
