摘要
揭示了５０年代以来热带三大洋海表温度（ＳＳＴ）长期变化的两个基本构成（线性增温及ＥｌＮｉｎｏ－ ＬａＮｉｎａ振荡），并比较了它们在三大洋中的典型程度。在此基础上重点分析了热带太平洋西、中、东部ＳＳＴ长期变化的差异，指出热带西太平洋ＳＳＴ长期变化中ＥｌＮｉｎｏ－ Ｌａ Ｎｉｎａ振荡相对较弱。
This paper reveals the two basic components i.e. linear warming and El Nino-La Nina oscillation, of the long term variations of sea surface temperature(SST) in the tropical Pacific,Atlantic and Indian oceans since the 1950s,and their intensity in the three oceans is compared. On the above basis efforts are focused on analyzing the differences in long term variations of SST of the western、central and eastern tropical Pacific, and it is pointed out that the El Nino-La Nina oscillation is relatively weak in the long term variations of SST of the western tropical Pacific and the linear warming trend is replaced by interannual strong and weak oscillations.
