摘　　要：基于SWAN海浪模式与ADCIRC风暴潮模式的耦合模式,综合考虑江苏辐射沙脊群海域的水深、地形、潮位对近岸浪的影响,采用非结构网格技术、并行计算技术以及海浪—风暴潮实时耦合技术,通过可调参数和物理过程的优化,建立适应于江苏辐射沙脊群海域的海浪精细化数值预报模型,网格分辨率最高达100m.通过对影响该海域的两次台风和两次冷空气过程的后报检验发现,该模型可以较好地反映海浪的传播过程,建立的预报系统能够满足海浪精细化数值预报业务化运行的需求.Based on the coupled mode of the wave model SWAN（simulating waves nearshore）and the storm surge model ADCIRC（advanced circulation）,considering about the influence of water depth,topography and tidal level on the coastal wave over the radiate sand ridges of Jiangsu province,unstructured grid technique,parallel computing technique and wave-storm surge real-time coupling technique were used in the wave fine forecast model.Through the parameter adjustment and physical process optimization,the wave fine numerical forecasting model suitable for the radial submarine sand ridges of Jiangsu is built.The highest resolution of the grid is 100 m.The forecasting model can preferably reflect the propagation process of the waves by the hind-casting test of two typhoons and two cold air processes.The forecasting system can meet the needs of the center for refined numerical forecast operation of waves.
