Contribution to the study of climate changes in Piedmont
In this report, we have studied the daily thermo - pluviometric series of 21 meteorological stations in Piedmont. The meteorological stations, belonging to ex-SIMN (Hydrographic and Marigraphic National Service), have been operating with continuity during 56 years, from 1951 to 2006. In order to cor...
