Résumé:
In this study was analyzed the annual trend and the global mean of Precipitation Water (WP) from 1986 to 2016. Data extracted from the ERA-Interim / European Center for Medium-Range Weather Forecasts (ECMWF) reanalysis were used. From these data was evaluated the Precipitation Water tendency spatial distribution. For the analysis of the climatic trend, Mann-Kendall and t-Student statistical tests were applied, observing the behavior of the global series. For the WP variable was found the average value of 24.4 mm for the whole period, corresponding to estimated volume for the whole atmosphere. The results indicate significant trends of 0.0246, 0.0121 and 0.0203 mm /year for HN; HS and the whole Globe, respectively. A positive trend was observed for some areas of globe as well as negative values, resulting the not homogeneous distribution, denoting a probable tendency to increase water vapor in the globe.
