摘要
本文分析研究了1949-1977年逐月东太平洋赤道海区海表面温度、1949-1980年逐月南方涛动指数以及1954-1984年逐月北半球西太平洋副热带高压(以下简称副高)特征指数等资料。结果表明:东太平洋赤道海区水温异常增高及降低与副高的异常变化之间存在6-9个月的时滞关系;副高的强弱变化与南方涛动的异常变化之间存在时滞3-5个月的相关关系;而南方涛动又与东太平洋赤道水温的变化存在某种联系,尤其是E1 Nino及反 E1 Nino发生期更为明显,它们之间存在同期到时滞3个月的相关关系。
The results indicated that unusual changes of the sea surface temperature in Eastern Equatorial Pacific are closely linked with those of the subtropical high, and that there is a time lag of about 6-9 months between them.There is a close relationship between changes of the subtropical high and the southern oscillation, and there is a time-lag of about 3-5 month, and the sonlhern oscillation is concerned with the sea surface temperature in Eastern Equator, especially when El Nino event or reverse El Nino event occurs, and there is a time-lag of about 3 months.
