【摘要】：基于SWAN模式和折繞射模式,本文對臺灣海峽和平潭島附近海域的海浪要素進行數(shù)值模擬。首先通過SWAN模式得到實時預報的高時空分辨率的波高、周期和波向等海浪要素數(shù)據(jù),為折繞射模型提供波浪邊界,進而對重點海區(qū)近岸波浪進行折繞射計算,最后對數(shù)值預報結果進行統(tǒng)計檢驗及預報分析。經過驗證,預報結果與實測數(shù)據(jù)基本一致,預報效果較好。研究成果可為平潭海浪預警報業(yè)務提供技術支撐,也可為海浪災害應急管理及沿海規(guī)劃等提供參考依據(jù)。
[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.
