This study examines the effect of the Indian Ocean Dipole (IOD) on the precipitation variability in the European region. The observed summer precipitation response to IOD-related sea-surface temperature anomalies is reproduced using Atmospheric General Circulation Model (AGCM) ensemble experiments and analyzed using observations and re-analyses patterns. Precipitation associated with the strong negative independent IOD events (while El-Nino/Southern oscillation-related effect excluded) may increase up to 30–40 mm/month according to observations/re-analyses data and up to 10–12 mm/month according to numerical ensemble AGCM simulation experiments over the Central European area and decrease at the eastern part of the Russian Plain and the Ural Mountains.
