使用1984—1989年期间中美海-气相互作用合作研究及法国ORSTOM完成的沿165°E断面共17个航次调查中的温、盐资料,对1986—1987厄尔尼诺(E1Nino)及1984-1985,1988年反厄尔尼诺(LaNina)事件期间海洋上层温、盐结构的变化作了分析。文章指出,165°E断面温、盐结构的变化具有明显的厄尔尼诺-南方涛动变化周期之特征;研究期间E1Nino与LaNina温、盐结构的差别主要表现在盐度分布及次表层温度结构的不同;165°E断面上的温、盐结构在E1Nino及LaNina期间的变化是各种海-气相互作用结果的反映,其中赤道带纬向风及赤道表层流系的变化是该海区温、盐结构变化的主要原因。
The temperature and salinity data from 17 voyage surveys along the 165 ° E cross section completed by the Sino-U.S. Sea-Atmospheric Interaction Study conducted by ORSTOM in France during the years 1984-1989 were used for the 1986-1987 El Nino and 1984-1985, 1988 Changes in the ocean’s upper temperature and salt structure during the La Niña event of the year were analyzed. The paper points out that the changes of temperature and salt structure at 165 ° E have the characteristics of the El Niño-Southern Oscillation period. The differences of temperature and salt structure between E1Nino and LaNina during the study period are mainly attributed to the different salinities and sub-surface temperature structures ; The variation of temperature and salt structure on the 165 ° E section in E1Nino and LaNina is a reflection of various sea-air interaction results. The change of zonal wind in the equatorial zone and the equatorial surface current is the change of temperature and salt structure The main reason for change.
