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

Analysis of Spatial and Temporal Distribution of Precipitation During the Last Eighty Years in Trentino (Italian Eastern Alps)

The climate of the Trentino area is not homogeneous, being influenced by an extremelyinteresting interaction of orographic variety and dynamics of air masses (deriving from geographic position, i.e. transition between Mediterranean and continental domain). As a consequence, in a few kilometres we pass from warm sub-Mediterranean climate to glacial and continental-dry ones. Several factors contribute to create many different topoclimatic situations (often more relevant than 86 ICAM/MAP 2003 May 2003 larger scale factors): altitude varies from 70 and 3905 m a.s.l., mountain belts, massifs and valleys are irregularly distributed and oriented, the Adriatic sea is not far from the southern end, snow and glaciers are frequent at higher elevations
