摘　　要：据海洋调查船“向阳红14”号和“向阳红16”号在1985年12月—1986年3月期间观测到的XBT及CTD资料分析了热带西太平洋1985—1986年冬季次表层热状况的分布特征。在1985—1986年冬季,热带西太平洋亦道附近海域,表层暖水比常年深厚,温跃层的纬向坡度比常年大。在130°E剖面上,8°N附近次表层等温线升高,这表明在太平洋西部,北赤道流及北赤道逆流比常年加强。这些海洋次表层热状况特征与Wyrtki等人指出的埃尔尼诺(El-Nio)事件发生前的热带西太平洋热状况相符。Some features of subsurface thermal state was described on basis of the CTD and XBT data obtained by R/V XIANGYANGHONG 14 and 16 during the period from December 1985 to March 1986, in the Western Tropical Pacific Ocean. In the 1985-1986 winter, the surface layer warm water and the western slope of the thermocline near the equaator was thicker and sharper than in a normal year. The isotherm near 8°N at 130°E section was raising, which showed that the North Equator Current and North Equator countercurr-ent was stronger than during a normal year in the Western Pacific . These characteristics of the thermal state were consistent to that of pre-El-Nino , as described by Wyrtki (1982) et al.
