【摘要】：基于SWAN模式和折绕射模式,本文对台湾海峡和平潭岛附近海域的海浪要素进行数值模拟。首先通过SWAN模式得到实时预报的高时空分辨率的波高、周期和波向等海浪要素数据,为折绕射模型提供波浪边界,进而对重点海区近岸波浪进行折绕射计算,最后对数值预报结果进行统计检验及预报分析。经过验证,预报结果与实测数据基本一致,预报效果较好。研究成果可为平潭海浪预警报业务提供技术支撑,也可为海浪灾害应急管理及沿海规划等提供参考依据。
[Abstract]:Based on the SWAN model and the refraction model, the wave elements in the waters near the Taiwan Strait and Pingtan Island are numerically simulated in this paper. Firstly, the wave elements such as wave height, period and wave direction of real-time prediction are obtained by using the SWAN model to provide the wave boundary for the refraction diffraction model, and then the refraction diffraction calculation of the coastal waves in the key sea area is carried out. Finally, the numerical prediction results are statistically tested and analyzed. Through verification, the forecast result is basically consistent with the measured data, and the forecast effect is better. The research results can provide technical support for wave pre-warning service in Pingtan, and provide reference for emergency management of wave disaster and coastal planning.
