摘　　要：粤东地区是我国沿海经济较为发达的地区之一,也是遭受风暴潮灾害较为严重的地区,本文重点分析了自1969年以来40年间影响粤东沿海的典型风暴潮过程,并建立起了一个适用于粤东沿海地区的高分辨率的风暴潮数值预报模式。此模式采用变网格技术,在可以保证使计算区域足够大的基础上,又能实现对重点区域的河口、海湾等地形加密处理,精细地刻画出其周围地形,从而保证了计算的准确性。通过对历史上影响该地区较为严重的台风风暴潮的模拟结果来看,此模式对该区域台风风暴潮的模拟效果良好。同时也可以将该模式较好地推广应用到其他地形较为复杂的区域进行台风风暴潮预报。The Eastern Guangdong coastal region is one of the most developed economies in China,and is also one of areas suffered the storm surge disaster.The characteristics of typical storm surge since 1969 is analyzed.In order to better relief the storm surge disaster of the Eastern Guangdong coastal region,a new storm surge mod-el is established to simulate and forecast the storm surge.The model,with a variable grid,could not only cover a large enough area,but also distinguish the tiny topography of bays,estuaries and so on.The model is used to simulate an historical worst typhoon storm surge event,and shows its excellent applicability.The model can also be used in other areas to better serve the work of marine disaster prevention and mitigation.
