Abstract：Jelesniansk is used as typhoon model to simulate wind field,and CCMP wind field is superim-posed to reconstruct wind field.The wind field structure characteristics during typhoon Herb were ana-lyzed by reconstructing the wind field.The three-dimensional ocean numerical model FVCOM was used to simulate the astronomical tide and storm surge in Xiamen sea area.Through error comparison,it is found that the simulated values were in good agreement with the measured ones.It showed that the simulation results could well reproduce the characteristics of storm surge in Xiamen sea area.Based on the simulation results,the spatiotemporal variation characteristics of three-dimensional sea current and water level during typhoon were analyzed.It was found that the temporal and spatial variation of the typhoon wind field was the main reason for the change of the flow direction and velocity of the storm surge.The distribution of increasing water was mainly affected by wind field,wind-generated current and shoreline characteristics.The increasing water area was mainly concentrated in the typhoon center and the area where the typhoon onshore wind acts for a long time.Water reduction often occurred in ar-eas where the offshore wind acted for a long time.
