| Abstract: |
| Using Reynolds and Smith 1950~1998 re-constructed monthly-mean SST to discuss the relationship between the ENSO and Indian Ocean dipole (IOD) and their possible connection with the onset of South China Sea summer monsoon (SCSSM), the results are obtained as follows:Most of IOD events have a closely positive relation to simultaneous ENSO events in summer and autumn.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 Niño (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 Niño) 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. |
