摘要:

大连黄海、渤海海浪数值预报系统采用WAVEWATCHIII模式进行海浪预报,预报产品包括48 h内浪高、周期、浪向的逐3 h预报,并对其进行检验。结果表明:WAVEWATCHIII模式对渤海中部浪高模拟较好,浪高预报TS为71.7 %,对近岸海区浪高模拟相对差些。个例的检验表明,浪高最大值模拟较好,模拟浪高最大值出现的时间与实况基本吻合,浪高变化趋势预报也较好。AVEWATCHIII模式对两个周期个例进行检验,预报误差最低可达到0.17 s,预报效果较好。

Abstract:

Sea wave was forecasted by the WAVEWATCH III model in the Yellow Sea and the Bohai Sea of Dalian. The products from the sea wave numerical forecast system include sea wave height, sea wave period and sea wave direction every three hours within 48 hours, and all were tested. The results indicate that the sea wave height could be simulated well by the WAVEWATCH III model in the middle of the Bohai Sea and TS (Threat Score) of sea wave height reaches 71.7%, while that is not well near the coast. The analysis of some cases shows that the maximum sea wave height and the trend of sea wave height could be simulated well. The occurrence time of the maximum sea wave height from the model agrees with that of the observation. Moreover, the simulated two sea wave period cases are tested, and the lowest error is 0.17s. The forecast effect of sea wave period by the WAVEWATCH III model is good.
