Regional differences in the influence of the North Atlantic Oscillation on seasonal river runoff in Poland
In this paper, an analysis of monthly and seasonal runoff volumes in two stages of the North Atlantic Oscillation are presented. The analysis embraced runoff at 146 profiles located on 96 Polish rivers during the years 1951–2000. The changes in the runoff conditions of Polish rivers in the two NAO s...
