| 摘 要： | There are obvious periodic oscillations in the observations of storm surges in the East China Sea . The storm surges are not only controlled by the wind stresses and isolated long wave 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 by using a two dimensional numerical model. In our numerical experiments we use the data of the storm surge induced by Typhoon 8114 . The calculations tally with the measured data well. The results indicate that the periodic osculations occurring in the elevations of the surge are 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 tides and storm surges is taken into account.
