摘要 在浪一流耦合的概念下,对Princeton Ocean Model(POM)模式进行改进,增加特征波参数下的海浪混合作用,并把潮流和环流同时模拟,得到了渤海、黄海、东海典型的环流和水文特征,特别是夏季黄海的温跃层现象,夏季长江冲淡水扩展路径以及我国东部海域冬季和夏季典型环流等.研究表明,海浪的作用使海洋上层混合得更均匀,潮流的作用使海洋底层混合得更均匀,二者是温跃层形成的重要原因;考虑潮效应模拟流场,由于潮扩散和潮余流的作用,长江冲淡水路径与实际观测更为符合。 Based on wave-current coupled numerical model, circulation and tide in the Huanghai Sea and the East China Sea are studied simultaneously. The model simulated the observed seasonal currents and main characteristics, in particular, Changjiang diluted water route in the East China Sea, the cold water mass and thermocline in the Huanghai Sea in summer, the winter and summer circulation in the Bohai Sea, Huanghai Sea and East China Sea. As the result shown, the temperature of upper and bottom layers tends to be uniform by the mixing of wave and tidal mixing, respectively, which are main dynamical mechanism to form thermocline. The modeled vertical temperature structure coincides well with the observations.
