ABSTRACT - Regional Aspects of the Variability of Atmospheric Precipitations in Winter and Summer Seasons in Europe during 2001-2090. A large number of studies have shown that precipitation have a spatial and temporal variability higher than temperature. The importance of the analysis regarding this topic emerges from the fact that the spatial-temporal variability of the atmospheric precipitation has a strong impact upon the environment and human society. The aim of this study is to identify the main changes which will occur in the amount of precipitation in Europe in winter, and summer. This study is based on regional climate models used to evaluate the future evolution of precipitation patterns in Europe during 2001-2090. We used the output regional climate model, CLM_B1_1_D3, based on the climate scenario IPCC, B1. Our results have shown that the relative pluviometric differences between the analysed periods reveal a more significant downtrend in the southern Europe and an uptrend at higher latitudes, in summer. In the winter season the amount of precipitation will decrease in the central and southern regions of the continent, while in northern and north-eastern areas precipitation amount either will remain constant or will increase by up to 25%.
