摘　　要：基于CCMP风场资料,采用无结构网格、浪-流双向实时耦合模型FVCOM-SWAVE,模拟强热带风暴"米雷"在中国近海区域产生的海浪场,将耦合模型模拟的有效波高和平均周期与实测浮标资料进行比对,发现模拟结果的各类误差总体较小,说明耦合模型能够较好地模拟考虑浪流相互作用下中国近海台风浪过程。对比考虑潮汐引起的水位变化与不考虑水位变化情况下对耦合模型模拟结果的影响,发现在近岸区域考虑潮水位情况下的有效波高和平均周期模拟结果周期性特征明显,说明潮汐对耦合模型在近岸处有效波高的模拟影响显著。Based on the CCMP（Cross Calibrated Multi-Platform）wind data,the wave field created by typhoon ＂ Meari＂ was simulated by FVCOM-SWAVE which was an unstructured grid,two-way,concurrent wave-current coupling model.Comparisons between the calculated values of coupled model and the measured data of significant wave heights and averaged periods show that each kind of errors was reasonable,and the coupling model could preferably simulate the process of typhoon waves of China offshore when wave-current interaction was considered.In contrast to the experimental situation without regard to the open tide boundary,the significant wave heights and averaged periods had noticeably periodic characteristics in the coastal region in terms of the tide.It indicated that tide had significant influence on the significant wave heights in the coastal area.
