文中,根据“中美热带西太平洋海气相互作用联合研究”第1—4航次考察的资料结合美国NOAA提供的SST资料和Wyrtki博士提供的水位资料,对1986—1987年埃尔尼诺事件的发生、发展和消衰过程中的海洋事件作了综合分析.指出,这次埃尔尼诺是一个中等偏强的事件.SST场和水位场的宏观变化是同步和相似的,并且都与风场特征有关.次表层温度结构的变化是与上层暖水的东向输送相对应.在此期间,热带西太平洋的流系结构和方向发生了异乎寻常的变化.在埃尔尼诺爆发前期,南赤道流较强,暖水在西太平洋堆积;在爆发期内,则在12.5个纬度带内形成东向流,向东输送暖水;在消衰期内,北赤道逆流变弱、而南赤道逆流变强;在埃尔尼诺结束后,海洋转为动力调整,并在约12个纬度范围内变为西向流.在这次埃尔尼诺期间,向东输送的暖水总量为11.4×10~(14)m~3,此量比1976年埃尔尼诺多1/3,而比1982—1983年埃尔尼诺少2/5.
According to the data of the first to voyage 1-4 experiments conducted in the Sino-US Tropical Pacific Ocean Air-Sea Interaction Study and the SST data provided by the United States NOAA and the water level data provided by Dr. Wyrtki, Occurrence, development and decline of the ocean event made a comprehensive analysis pointed out that this El Niño is a moderately strong event.Small field and water level changes in the macro-synchronous and similar, and both with the wind Field characteristics.The changes of subsurface temperature structure correspond to the eastward transport of the upper warm water, during which the structure and direction of the flow in the tropical western Pacific have changed dramatically.In the early stage of the El Niño eruption, The south equatorial current is stronger and the warm water is piled up in the western Pacific. In the period of outbreak, an eastward flow is formed in 12.5 latitudes and warm water is sent to the east. In the decay period, the northern equatorial countercurrent becomes weaker while the south The equatorial countercurrent became stronger; after the end of El Niño, the oceans became dynamically adjusted and turned westwards within about 12 latitudes. During this El Nino period, the total amount of warm water delivered east was 11.4 × 10 ~ (14) m ~ 3, which is 1/3 more than El Nino in 1976, While 2/5 less than El Nino in 1982-1983.
