Analysis of spatial and temporal distribution of precipitation in Trentino (Italian Eastern Alps): Preliminary Report

he records of 92 pluviometric stations located in the Trentino Province (Italian Eastern Alps) were analyzed in order to find significant features in their spatial and temporal distribution. Differentiation of climatic regimes was detected, as well as the influence of many topographic-geographic parameters. Analyses of the data from the 20 stations with the best continuity of records indicate some periodic trends, with a major influence of those having a wavelength of ca. 26.7, 36.9 and 13.5 years. Also non strictly periodic Mediterranean oscillations influences the precipitation in the study area
