| 摘 要： | 渤海是我国重点保护水系之一。为了控制水域污染,制定废水排海标准,首要步骤须查明入海污染物质的扩散过程。在渤海,潮流是形成污染扩散的主要营力之一,为此首先计算渤海的潮流及潮余流场。近二十年来,随着电子计算机的迅速发展和计算技术的进步,潮汐动力学进入了数值研究的新阶段。这一新方向的特点,是以求解自然条件下长波方程的初值——边值问题为出发点,研究以往所不能解决的许多复杂现象。

| Abstract: | The tidal current and tide-induced residual circulation of the Bohai Sea are calculated by a numerical model braced on the two-dimensional nonlinear long wave equations with the semi-implicit alternating direction method.As a result, the spafial distributions of amplitudes,phases, tidal ellipses in tide-M2 and residual current are obtained.The tidal wave systems of M2 and K1 of the Bohai Sea are reproduced by the model.The computed co-tidal and corange lines of M2 and K1 are well in agreewent with harmonic constants obtained by tide gauge stations.The comparision between the computated and observed values exhibits a considerable agreement. The computation of the tide-induced residual circulation produces a flow pattern with three major eddies, and many minor individual eddies,and this flow pattern is strongly supported by the available oil pollution monitoring. |
