摘要
本文选用1951—1986年赤道太平洋(10°S—10°N,180—85°W)海表面温度(SST)与南方涛动指数及副热带高压特征指数,重点探讨了海洋与大气之间的相互作用过程,得出了起主导作用的因素,认为与选取代表赤道太平洋平均海面温度的海区范围和选用代表南方涛动的两个气压站有直接关系。
The interrelationship among the sea surface temperature (SST), the Southern Oscillation and the indices of Subtropical High from 1951-1986 are analysed. The influence of the ocean over the atmosphere and vice versa are also discussed. The intensity and the time-lag of the ocean's influence upon the Southern Oscillation and the Subtropical High are closely related with Equatorial current. SST plays a major role in its interaction with SO1, by one month ahead of the latter. The cause for the difference is the variation of the Easter's air pressure in SO2 preceded that of the Tahiti's air pressure about 1-2 months. For this reason, when discussing Ocean-Atmosphere interaction, the factor playing the leading role depends on the area of SST and the station pressure of the Southern Oscillation.The anomaly variation of Eastern Pacific Ocean SST preceded that of the area of the Subtropical High about 6-7 months. The anomaly variation of Eastern Pacific Ocean SST preceded that of the ridge point of the Subtropical High about 5-6 months.
