| 摘 要： | 本文设计了一个新的超浅海风暴潮的动力学模型。该模型的特点是依据海域水深的不同,分别采用文献2]和3]所建议的模型,其中海水的湍粘滞性被假定是水深的已知函数,并对地转效应作了近似的考虑。利用表征渤海风潮主要特征的模型风应力场和有限元技术,对所提出的模型进行了数值试验和比较。结果表明,它对渤海风潮的描述比文献4]和5]有了进一步的改善。

| Abstract: | Based on the models presented in 2] and 3], a new mixed model is developed. It is the characteristic of the mixed model that the model in 2] is used in a smaller and shallower （the depth is smaller than 10 meters） region while the model in 3] is used in a larger and deeper region （the depth is greater than 10 meters）. Two models are matched by the natural oonditions that both total transport, and surge height are continuous. The model in 3] "is an ultra-shallow water storm surge model which takes into consideration the effects of the earth's rotation and the quadratically depth-varying eddy viscosity. Using the model wind fields as the guide for representing the effects of the wind-stress forcings in our model, the numerical simulation of the Bohai Sea wind tides is made successfully by finite element method. |
