| 摘 要： | 利用RAMS大气模式给出的20年风场资料,利用SWAN近海波浪模式对渤海海域的波浪进行了20 a数值计算.通过与一般过程和大风过程的实测资料的对比后发现.波浪模拟值与实潮值符合地较好,SWAN模式适合渤海海域波浪的计算。通过分析发现.辽东湾常浪向为SSW。强浪向为SSW;渤海中部常浪向为S,强浪向为NE;渤海海峡常浪向为NNW,强浪向为NNW;莱州湾常浪向为S,强浪向为NNE;渤海湾常浪向为S.强浪向为NE。渤中偏东南海域(38°～39°N,119.5°～120.5°E)多年一遇有效波高最大.其中百年一遇有效波高最大值达到6.7m。

| Abstract: | Using 20-year wind data from RAMS(Regional Atmospheric Modeling System), the SWAN model was operated to obtain 20-year wave parameters of the Bohai Sea.Ob- served wave data of several wind processes including normal wind and strong wind are chosen to compare with the data from the SWAN model.The results show that wave heights of the simulation agree very well with the observations,so the SWAN model is proper to simulate the wave field of the Bohai Sea.The study indicates that both of the main wave direction and the strong wave direction in Liaodong Bay are SSW,in the center of the Bohai Sea are S and NE,respectively;at the Bohai Channel are NNW and NNW,respectively;in the Laizhou Bay are S and NNE,respectively;and in the Bohai Bay are S and NE,respectively.The maximum significant wave height of multiyear return periods is at the southeast of the center of the Bohai Sea,and the 100-year return period significant wave height can reach 6.7 me- ters. |
