[1] Gridded monthly precipitation data for 19792006 from the Global Precipitation
Climatology Project are used to investigate interannual summer precipitation variability
over Europe and its links to regional atmospheric circulation and evaporation. The first
empirical orthogonal function (EOF) mode of European precipitation, explaining
17.2%22.8% of its total variance, is stable during the summer season and is associated
with the North Atlantic Oscillation. The spatialtemporal structure of the second EOF
mode is less stable and shows monthtomonth variations during the summer season. This
mode is linked to the Scandinavian teleconnection pattern. Analysis of links between
leading EOF modes of regional precipitation and evaporation has revealed a significant
link between precipitation and evaporation from the European land surface, thus,
