中文摘要：

用雷纳兹和史密斯 1950 ～ 1998 重建了与华南海夏季风(SCSSM ) 的发作讨论在 ENSO 和印度洋偶极子(IOD ) 和他们的可能的连接之间的关系的每月平均数的 SST，结果如下被获得：大多数 IOD 事件在夏天和秋天有一种密切积极的关系到同时的 ENSO 事件。在秋天(成熟阶段) 的 IOD 事件也是仔细与在冬季(成熟阶段) 的 ENSO 事件有关。当这些二种事件发生在阶段时，我。e。， positive (negative ) IODevents 被结合 El Nino (拉·尼娜) 事件，他们总是被跟随由迟了(或早) SCSSM 的发作。相反，当这些二种事件从阶段发生时，我。e。positive (negative ) IOD 事件被结合拉·尼娜(El Nino ) 事件，他们被 SCSSM 的正常发作跟随。另外，单个 IOD 事件或单个 ENSO 事件不能对应于很好 SCSSM 的反常发作。

英文摘要：

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 E1 Nifío （La Nifía） 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 Nifia （ E1 Nifío） 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.
