PRÉCIPITATIONS NEIGEUSES, TYPES DE TEMPS ET SPORTS DANS LA VALLÉE DE SUSA (ITALIE): L’APPROFONDISSMENT DE LA RELATION ENTRE CLIMAT ET TOURISME D’HIVER

Snowfall, weather types and sport in Susa valley (Italy): the further study on the relationship between climate and winter tourism. The study examines the climate conditions in the Susa Valley with the aim of interpreting results linked to the tourist trend, from 1990 to 2010. We had recourse to classical climatology to individuate the most snowy winter season, that it is the 2008/09. Simultaneously, the monthly values of arrivals facilities, have been analysed in order to find a relation between nivometric and tourist flow trend. Given that the succession of weather types affecting Piedmont strongly determines the trend of variables involved, researchers had recourse to dynamic climatology. The latter considers every day, the main meteorological variables analysing their rate, that, alongside the reading of isobaric maps, allowed us to calculate the main air masses and the frontogenesis and interpret the tourist trend in a better way.
