本文以4个主要分潮之和为开边界输入条件,对黄海天文潮及8114、7708、7303号台风潮与天文潮耦合作用进行数值模拟,计算结果与实测值基本相符,又通过模拟的流场和水位的变化,分析了不同风暴条件下,天文潮与风暴潮及其流场耦合作用的时空变化规律,从水位场流场整体上研究其相互关系及其动力机制。讨论了几种主要动力因素在非线性耦合作用中的作用,取得了一些有益的结果。
In this paper, the input conditions of the four major tidal wave are regarded as the boundary conditions. The numerical simulation of the coupling between the Yellow Sea astronomical wave and the typhoon 8114, 7708 and 7303 astronomical tide is carried out. The calculated result is in good agreement with the measured value, Field and water level. The temporal and spatial variation of the astronomical tide, the storm surge and their flow field under different storm conditions are analyzed. The interaction between the astronomical tide and the storm surge and its flow field are studied. Several main dynamic factors are discussed in the role of nonlinear coupling, and some useful results have been obtained.
