摘 要:为了检验FVCOM海洋模式模拟台风浪的效果,分别以CCMP风场和WRF模式模拟风场构建驱动台风浪的海面风场模型,基于FVCOM海洋模式,以2010年的"凡比亚"台风为例进行台风浪数值模拟,并用站点浮标资料进行了模拟结果检验。结果表明,FVCOM海洋模式模拟的水位、有效波高结果与实际观测结果的整体误差较小,模拟效果较好;受到风场与地形的影响,最大增水与减水的区域分别位于台风中心的左侧沿岸和右侧沿岸;风场与表面流场的模拟结果也符合台风过程中的风生流分布特征,即风场与表面流场方向、大小存在一致性。此外,对比分析2种不同海面风场模型下的台风浪模拟结果发现,二者均能较好地模拟此次台风过程,但存在一定的差异,增加WRF模式模拟风场作为强迫驱动风场模拟的有效波高更接近观测值。In order to test the effect of FVCOM ocean model simulating typhoon waves, using CCMP wind field and WRF model to simulate wind field, based on FVCOM ocean model, taking typhoon "Fanapi" in 2010 as an example for numerical simulation of typhoon waves, and the simu- lation results were carried out with the site data. The results showed that the overall error of the water level, significant wave height results from FVCOM model is small, the simulation effect is good. Affected by the wind field and the terrain, the area of maximum increase and decrease wa- ter located at the left side of the typhoon center and the right side of the coast. Wind field and surface flow field simulation results is also accord to the characteristics in typhoon process. In addition, through comparing and analyzing the simulation results of the typhoon waves in two different sea surface wind fields, it was found that the two wind fields can simulate the typhoon process, but there are some differences, the simulation of wave height is closer to the observed when increase the wind field simulated from the WRF model.
