摘要
根据黄、渤海区20 a中最大风速对应的风场过程,利用SWAN模型模拟风浪的成长过程,利用针对模型推算所得的烟台芝罘岛附近海域的系列波浪要素,进行P-III型曲线的拟合分析,得到不同重现期条件下的特征波浪要素。模型计算过程中,只需对美国NCEP和欧洲ECMWF风场后报资料进行简单校正,据此通过SWAN模型推算的特征波浪要素值就可与根据芝罘岛海洋环境监测站现场观测资料推断的波浪要素值基本一致。
According to wind field process that corresponds to maximum wind in Huanghai Sea and Bohai Sea regions in the past 20 years, wave generating process is simulated by using SWAN model, and series wave parameters around Zhifu Island of Yantai are induced by the simulation calculation to carry out P-III curve fitting analysis, from which the characteristic wave parameters for different return periods are obtained. In the simulation calculation, the characteristic wave parameters that are induced by using SWAN model agree with those observed at the Marine Environmental Monitor Center of Zhifu Island subject to a simple correction being conducted for the hind-casting wind data of NCEP and ECMWF.
