摘要
一个二维数值模式被用于研究长江口以外海域的风暴潮与天文潮的非线性相互作用。用这个模式模拟了 1981年 8114号台风与天文潮共同作用下所引起的风暴潮增水。 8114号台风是近 2 0年中最重要的台风之一。该台风登陆点附近有吴淞验潮站 ,这里有完整的风暴潮水位记录。计算结果与该站实测值符合较好 ,说明模拟是成功的。此外 。
A 2 dimensional numerical model is used to study the non linear interaction between storm surges and astronomical tides in the sea area off the Changjiang River mouth. By using this model the storm surge residual caused jointly by the 8114 Typhoon and tides is simulated. The 8114 Typhoon is one of the most important typhoons in the recent 20 years. There is a tidal station, Wusong Station, near the place where the 8114 Typhoon landed. Here there are complete records of water level caused by the surge. The simulated results and the observations tally well. This indicates that the simulation is successful. In addition, from the simulated results some useful conclusions have been drawn.
