【摘要】 <正>黑潮源地是否有一分支进入南海,这是一个长期以来没有得到确证的重要问题。我国学者在1958—1960年的海洋调查研究中指出,南海东北部的外海水来源于太平洋,是太平洋水团进入南海后进一步变性形成的,并且在2—4,12月份都发现有黑潮分支到达粤东沿岸的迹象。朱祖佑进一步指出:在冬季,黑潮的一个分支通过巴士海峡进入南海,与盛行的东北季风产生的西南向表层流会合;而当夏季南海盛行西南季风时,这支黑潮支流与西南季风的表层流会合,向东北流入台湾海峡。这是迄今为止,有关黑潮分支进入南海的一个肯定性意见。最近,黄企洲指出,确有黑潮支流通过巴士海峡进入南海。更多还原

【Abstract】 In terms of temperature,salinity,dynamic height, and part of the actual measured data of sea current, obtained from four NW-SE cross-sections in the NE part of the South China Sea(north of 18°0’,112-119°), namely, the section off Chuandao Islands,that off Zhujiang Mouth,that east of Jieshi Bay,and that off Shantou, conducted by the South China Sea Institute of Oceanology, Academia Sinica during the period of Jan.and Dec.of 1981, and Jan.and Feb.of 1982,with the reference to part of a small amount of dynamic height data abroad, characteristics of the warm current in the investigation time are analyzed.It is also revealed that on the right side of the main stream axis of the warm current occurs a rather strong SW-ward current.Velocity,current width and transport of this current are larger than those of the warm current in the same period,it is also thicker and broader.Preliminary analyses demonstrate that this SW-ward current is a branch of Kuroshio in the South China Sea,hence,it is named the South China Sea Branch of Kuroshio.更多还原
