Decadal variability of the Danube river flow in the lower basin and its relation with the North Atlantic Oscillation
Abstract The decadal variability (>5 years) of the Danube river flow in the lower basin and its connection with the North Atlantic Oscillation (NAO) is analysed for the period 1931–95. Associated linkages with precipitation (PP) in the European sector, global sea surface temperature (SST) and atm...
