在对影响垂直混合的物理过程进行分类的基础上，讨论了表面波动量和潮流引起的扩散率及其对垂直温度结构的影响。基于三种混合方案，模拟了黄海和东中国海的垂直温度结构。结果表明，夏季，面波诱导的混合对YECS上层混合层的形成起着关键作用。潮汐混合作用将底层控制在30m以内，是形成南黄海平台型温度结构的主要因素。潮汐混合与强烈的面波混合共同作用，使温跃层在YS南部东岸附近通风。东海深层的双重冷核有不同的成因。西部是冬季冷水的维持，东部是环流的配置。模拟VE..。
Abstract After a classification of the physical processes which affect the vertical mixing, diffusivity induced by the surface wave momentum and tidal currents and its influence on the vertical temperature structure are discussed. Based on three mixing schemes' the vertical temperature structure of the Yellow and East China Seas (YECS) is simulated. Results show that in summer, the surface wave-induced mixing plays a key role in forming the upper mixed layer in the YECS. The tidal mixing controls the lower layers within 30 m above the bottom, which is the main factor in forming the platform-shaped temperature structure in the southern Yellow Sea (YS). Together with the strong surface wave-induced mixing, the tidal mixing makes the thermocline ventilate near the east coast of the southern YS. The double cold cores in the deeper layers of the East Chine Sea have different causes. The western one is the maintenance of the winter cold water, while the eastern one is configured by circulation. The simulated ve...
