【摘要】 为解释黑潮水进入南海的方式 ,通过对 2 0 0 2年 5月 2 9日～ 6月 6日在南海及巴士海峡附近太平洋海域观测所得的资料进行水团分析 ,以四边形水团定量分析方法得到各水团在海区内的分布状况 ,同时分析了温度、盐度、密度和溶解氧的分布 ,并对在相同深度层次上的南海水和黑潮水性质进行了比较。观测海域的水团分为表层水团 (SW ) ,次表层水团 (SSW ) ,中层水团 (IW )和深层水团 (DW ) ,分别处于 0～ 5 0m ,5 0～ 3 0 0m ,40 0～ 10 0 0m ,10 0 0m以深。黑潮水进入南海 ,但是势力较弱 ,未能越过 119.5°E深入南海。更多还原

【Abstract】 The data observed from March 29, 2002 to June 6, 2002 with regard to the water masses in the northern South China Sea and Bashi Channel were analyzed with the quadrangle method. The distributions of temperature, salinity, density and dissolved oxygen were also analyzed. The properties of the South China Sea waters and the Kuroshio waters at the same depths were also compared. The waters in this area can be divided into four water masses: the Surface Water Mass(SW), the Subsurface Water Mass(SSW), the Intermediate Water Mass(IW) and the Deep Water Mass(DW). They are located respectively at the depths from 0m to 50m, 50m to 300m, 500m to 1 000m and below 1 000m. The Kuroshio water intruded into the South China Sea, but no Kuroshio water passed 119.5°E in the investigation period.更多还原
