2011). In turn, the meteorological conditions and riverine discharge are affected by
the variability of global climatic shifts (North Atlantic Oscillation, NOA, and
Southern Oscillation, SO) during different El Ni~ no–Southern Oscillation (ENSO)
periods or absence thereof. That is why we used anomalies in the Danube River
