中文摘要：

这研究调查了 JuneOctober (JJASO ) 的 interdecadal 可变性在有从 1958 ～ 2008 使用车站和分析数据的降雨异例的西方的太平洋和他们的协会的大、小的温暖的水池。结果显示在西方的太平洋的大、小的温暖的水池在 1986 附近显示出 interdecadal 移动。在西方的太平洋上的大温暖的水池年在 1986 以后被发现，而小温暖的水池年经常在 1986 前在整个时期被看见。分析结果也证明在西方的太平洋在在东南中国和温暖的水池的 JJASO 降雨有明显的 interdecadal 可变性。在 19581985 期间(小温暖的水池年) ，在降雨的减少在西方的太平洋在东南中国和温暖的水池上与 tropospheric 潮湿分叉和下沉运动被联系。然而，在 19862008 期间(大温暖的水池年) ，降雨的增加与 tropospheric 潮湿集中和上升运动被联系。进一步的分析证明那个大温暖的水池在表面贡献了增加在在西方的太平洋的温暖的水池上的潜伏的热流动。因此，在西方的太平洋在东南中国和温暖的水池上的水蒸汽的数量有增加，它在这些区域贡献了增加的降雨。

英文摘要：

This study investigated interdecadal variability of June–October（JJASO） the large and small warm pools in western Pacific and their association with rainfall anomalies using station and reanalysis data from 1958 to 2008.The results indicated that the large and small warm pools in western Pacific showed an interdecadal shift around 1986.The large warm pool years over western Pacific were found after 1986,whereas the small warm pool years were often seen throughout the periods before 1986.The analysis results also showed that there were obvious interdecadal variability in JJASO rainfall in Southeast China and warm pool in western Pacific.During 1958–1985（small warm pool years）,the decrease in rainfall was associated with tropospheric moisture divergence and sinking motion over Southeast China and warm pool in western Pacific.However,during 1986–2008（large warm pool years）,the increase in rainfall was associated with tropospheric moisture convergence and ascending motion.Further analysis showed that large warm pool contributed to the increase in surface latent heat fluxes over warm pool in the western Pacific.Thus,there was an increase in the amount of water vapor over Southeast China and warm pool in western Pacific,which contributed to increased rainfall in these regions.
