The aim of this study is to investigate the spatial correlation of water vapour, liquid water and rain amounts over Europe, North America and Japan. The study has been performed exploiting ERA-15 (concerning rain) and ERA-40 (concerning water vapour and liquid water) re-analysis data from ECMWF, considering at least 15 years, to assure the proper statistical stability to the results. In particular the Statistical Dependence Index χ [1] (SDI) has been calculated and its variation with distance has been considered.

Abstract
The aim of this study is to investigate the spatial correlation of water vapour, liquid water and rain amounts over Europe, North America and Japan. The study has been performed exploiting ERA-15 (concerning rain) and ERA-40 (concerning water vapour and liquid water) re-analysis data from ECMWF, considering at least 15 years, to assure the proper statistical stability to the results. In particular the Statistical Dependence Index χ [1] (SDI) has been calculated and its variation with distance has been considered.File in questo prodotto:
