| 摘 要： | 采用海洋三维热结构及环流模式，模拟了黄海在Ｍ２潮流混合作用下，夏季温度的分布和变化特征。从数值研究的角度，对黄海陆架水域的海洋锋现象，诸如苏北浅滩外、山东半岛东端、大连、木浦水域的锋面以及锋面沿岸一侧的表层冷水区的成因及分布进行了探讨，模拟结果再现了黄海陆架锋的潮生性质。

| Abstract: | The causes of summertime distribution and charater of temperature in the Yellow Sea were studied, using a three-dimensional thermal and cireulation numrical model. The temperature variation of seawater in summer due to the mixing effect of M2 tidal current in the Yellow Sea was simulated and compared with the temperabe variation due to the mixing by summr average wind stress. The continenall ocean fronts in the Yellow Sea such as the fronts outside the Subei shallows, in the southastem part of the Shandong Peninsula, in the waters nearby Dalian and Mokpo as well as the surface cold water between the front and coast, were studied. The simulating results tallied with the surface temperature distribution observed by satellite remote sensing and reproduced the tide-induced character of continental fronts in the Yellow Sea. The there-dimensional thermal and circulation model in the present paper was used for numerical simulation of hdal cimnt in the Yellow Sea focused on the process of periodic tidal mixing of temperature due to the boundary foree of M2 tide. The simulating results revealed not only the character of temperature distribution and vdriation in the tide-indued continental front areas of the Yellow Sea, but also the distribution of vertical tidal residual current for comparison with the distribution of temperature. For embodying the effect of tidal mixing on water temperature variation, the simulation study did not consider the thermal exchane process at the sea surfase and the salinity variation in themodel. In summer, the solar radiation and sea surface thermal exchange processes are very strong,so the numerical results here were used to study in detail the mechanism of tidal mixing to oceanthermal structure. |
