摘　　要：用11种假定情况对南海东北部冬季逆风流（简称冬季逆风流）是否产生进行数值试验。结果表明，除平底、静风假定外，南海东北部大陆坡上均有表层海水辐合带形成；该带是产生冬季逆风流的必要条件。经巴士海峡流入的黑潮水加强大陆坡区辐合带，加速冬季逆风流的形成。风应力、大陆坡是冬季逆风流产生的决定因素。冬季逆风流对风应力曳力系数（CD）及水平涡动系数（AH）的取值相当敏感。11 cases are supposed to see whether the winter upwind flow (WUF) will form in the northeastern South China Sea (NSCS). All numerical experiments show surface water convergence belt (SWCB) forming in the continent slope of the NSCS,except the conditions of flat bottom and calm weather, which is necessary conditions to form WUF. Kuroshio through Bashi Strait into the SCS strengthens SWCB and speeds up the formation of WUF. Winter wind stress and continent slope are determinants for WUF to form. WUF is very sensitive to CD and AH.
