摘　　要：分析了Holland模型风场和四象限非对称模型风场的差异和适用性,基于ADCIRC模型建立了适合华南沿海的高分辨率风暴潮模式,将上述两种模型风场作为强迫场分别模拟1117号台风"纳沙"风暴潮过程,结果表明:在珠江口、琼州海峡岸段的风暴潮模拟有了较大的改进,究其原因是四象限模型相比Holland模型更灵活、能够更好刻画"纳沙"台风非对称风场结构,说明该风场模型可用于改进风暴潮数值模拟。The difference and the applicability between Holland wind model and four-quadrant asymmetric wind model has been analyzed in this paper. Based on ADCIRC model, a high resolution storm surge model for the South China coastal area has been established to simulate the storm surge caused by the 1 117 Typhoon ＂ Nesat＂ with the two wind models as force fields respectively. The simulation results of using the four-quadrant asymmetric wind model have been greatly improved in the Pearl River estuary and the coast of the Qiongzhou Strait, and the reason is that the four-quadrant asymmetric wind model is better than the Holland wind model in describing the asymmetric wind field structure of ＂Nesat＂, thus the four quadrant asymmetric wind model can be used to improve storm surge numerical simulation.
