IOD events in autumn (mature phase) are also closely related to ENSO events in winter (mature phase). When these two kinds of events happen in phase, I.e., positive (negative) IOD events are coupled with El Nino (La Nina) events, they are always followed by late (or early) onsets of SCSSM. On the contrary, when these two kinds of events happen out of phase, I.e. Positive (negative) IOD events are coupled with La Nina (El Nino) events, they are followed by normal onsets of SCSSM. In addition, single IOD events or single ENSO events cannot correspond well to the abnormal onset of SCSSM. 收起<<
