| 摘 要： | 中国东海的风暴潮具有明显的周期性波动。凤暴潮除了决定于风应力和长波效应外,还受到天文潮与风暴潮相互作用的影响。本文利用一个二维数值模式对天文潮与风暴潮相互作用的水位进行了模拟。我们选取了8114号台风加以计算。计算结果与实测资料基本相符,由此说明水位曲线中的潮周期波动主要是由于天文潮与风暴潮之间的非线性相互作用所致。数值实验还表明,如果考虑到天文潮与风暴潮的相互作用可以显著改善水位的预报精度。

| Abstract: | There are obvious periodic oscillations in the observations of storm surges in the East China Sea. The storm surges are not only controlled bv the wind stress and isolated long waves caused by typhoons but also affected by the interaction between astronomical tides and storm surges. In the present paper we simulate the interaction between tides and storm surges bv using a two-dimensional model. In our numrical experiments we use the data of the storm surges induced by Typhoon 8114 The calculations tally with the measured data well The results indicate that the periodic oscillations occurring in the elevations of rhc surge arc mainly caused by the interaction between the tide and the storm surge. The numerical experiments also indicate that the forecasting precision may be notably improved if the nonlinear interaction between tide and and storm surge is taken into account |
