    Abstract: Andorra is located in the axial Pyrenees, in a climatic transition zone (Atlantic- Mediterranean). Hence, different atmospheric circulation types generate a high variability on the spatial distribution of snowfalls and windstorms. This leads to episodes with different spatial patterns of avalanche activity affecting in a different way several ski resorts located at very short distances between them. Our main, long term objective is the snow climatic zoning of Andorra taking into account three different factors: a) synoptic circulation types, b) historical nivometeorological records and c) the corresponding avalanche situation. As a first step, in order to characterize the snow climates, different data are being analysed and correlated: thickness of precipitated snow; days with snowfall of 20, 30, and 50 cm; accumulations of 20, 30, and 50 cm in 3 consecutive days; PIDA (artificial Avalanche triggering) days; results of PIDA (total shots, shot points, orientations, method, avalanche size, hours...); synoptic circulation types and occurred accidents. The expected results are the definition of the different snow climate zones of Andorra and different avalanche activity scenarios related to these zones. This result will help the different ski resorts in Andorra in their decision-making and risk management when artificial triggering of avalanches is required.
