通过对海面高度场和上层海洋热含量年际变化的分析,揭示了1997～1998El Nino期间热带东印度洋与热带西太平洋上层海洋的内在关系,在1997～1998El Nino事件爆发前期,海面高度距平信号首先在热带西太平洋出现,随后在热带东印度洋海区也出现了负距平。上层海洋热含量的负距平信号在El Nino前期也同样先出现在热带西太平洋,依据热带东印度洋和热带西太平洋年际尺度调整存在的联系,我们采用热带东印度洋海洋上层热含量距平的增长,估算印度尼西亚贯穿流的流量,得到的结果与观测具有相同的量级,这种间接估计表明热带东印度洋在1997～1998El Nino期间的异常,是可以部分经由热带西太平洋距平通过贯穿流而引起的。
Based on the analysis of the interannual variations of the sea surface height field and the upper oceanic heat content, the intrinsic relationship between the tropical East Indian Ocean and the upper tropical Pacific Ocean during the 1997 ~ 1998El Nino period was revealed. In the early period of the El Niño event from 1997 to 1998, the sea surface anomaly signal First appeared in the tropical western Pacific, followed by negative anomalies in the tropical eastern Indian Ocean. The negative anomaly signal of the upper ocean heat also appeared in the tropical western Pacific in the early stage of El Nino. Based on the inter-annual scale adjustment of the tropical East Indian Ocean and the tropical western Pacific Ocean, we used the anomalous upper troposphere of the tropical East Indian Ocean Growth, and estimated the flux throughout Indonesia, and the results obtained are of the same order of magnitude as the observations. This indirect estimation shows that the anomalies of the tropical East Indian Ocean during 1997-1998 El Nino can be partially transited through the tropical western Pacific anomalies caused.
