The stationarity of the ENSO teleconnection in European summer rainfall

El Niño-Southern Oscillation (ENSO) influence on European precipitation (Pcp) has been deeply analyzed. Most of the previous studies focus atmospheric response in wintertime during peak ENSO episode, showing boreal summer a season with marginal signal. Furthermore, stationarity teleconnection Europe not considered many works, which could mask possible nonstationary impacts other seasons like summer. In this research we find strong eastern Pacific-like leading variability mode Pcp, dipole-like configuration and linking Niño drier(wetter) conditions northern(southern) Europe. This relationship is limited to total cumulative but also low extreme Pcp. impact rainfall found from 1960s 1990s, 30 years-long period when position extratropical northern jet stream, acts as waveguide, favors pathway Strikingly, events behind reach their However, show that resultant Pcp depend characteristic seasons, be used for predictability purposes.
