Modulation of the relationship between spring AO and the subsequent winter ENSO by the preceding November AO

Abstract Previous studies indicated that the spring Arctic Oscillation (AO) exerts significant influences on the subsequent winter El Niño-Southern Oscillation (ENSO). This analysis suggests that the spring AO-ENSO linkage is highly modulated by its preceding November AO. When November and the subse...
