Winter precipitation in Western Italian Alps (1926-2010): trends and connections with the North Atlantic/Arctic Oscillation
Six snow depth and total precipitation time series recorded in Western Italian Alps between 960 and 2177 m a.s.l. have been analyzed to investigate variability and trends over the 1926-2010 period. The results outline a significant decrease of snow depth in the period 1951-2010 ranging from -0.2 cm/...
