摘　　要：准确的风场信息是波浪预报的必要前提,利用第三代海浪数值模式WAVEWATCHⅢ,结合台湾海峡3个测站的实测资料展开对比分析,探讨了在GFS、GRAPES和WRF 3种风场作用下对涌浪参数模拟的适用性。结果表明:3种风场模式中,GFS风场的整体风速水平与实测值相符,相关系数达到0.72,在该风场作用下KM、MS、PH站涌浪有效波高及平均周期的模拟效果最佳且表现稳定,其中MS站的相关系数分别达到0.72、0.67。Accurate wind field information is a necessary prerequisite for wave forecasting.This paper makes a comparative analysis by using the third-generation wave numerical model,WAVEWATCH Ⅲ and based on the measured data at the three observation stations in the Taiwan Strait,and the applicability of wind field models in surge parameter simulation under the action of the wind fields of GFS,GRAPES and WRF.The results show that,in the three wind field models,the overall wind speed level of GFS wind field is consistent with the measured value,and the correlation coefficient reaches 0.72.Under the action of this wind field,the simulation effect of the surge effective wave height and average period at the KM,MS and PH stations is the best and stable,in which the correlation coefficient at KM station reaches 0.72 and 0.67 respectively.
