Climatologie hivernale des versants alpins (Savoie) : types de temps, températures et vents.
Analyse des données météorologiques des domaines skiables.

Abstract : In mountainous area, the variability of the climatic parameters are still not well known at small scale. Indeed, the systematic measurements of temperature, humidity and wind's parameters are often restricted because of difficult climatic conditions, specially in winter. But since the production of artificial snow in the winters sports resorts began, it became possible to use the information of the very dense meteorological network of anemometers and probes installed for this purpose.
This Phd thesis aims at exploiting the data of French Alpine selected sites in the Savoie area (Les Menuires, Val Thorens, Aussois, Valloire).
A statistical and exploratory data analysis permit to answer the recurrent problematic of the mountain winter
climatology, mainly the influence of the meteorological large scale and the mountain topography on the small scale spatial and temporal variability of temperature and wind.
This research deals with the hourly and winter means temperature behavior, their inversions, the thermal gradients according to the weather type classification of the Savoie area.
A new model of the evolution of the winter thermal breezes is proposed, after having identified diurnal catabatic
breezes'mechanisms which were still unknown. Lastly, we propose real applications fort the management of skiing areas and artificial snow.
