摘　　要：南海是我国风暴潮灾害频发的海域之一,合适的拖曳系数参数方案能够提升风暴潮数值模拟的准确度,对于南海风暴潮的防灾减灾影响深远。本文基于影响南海海区的两次台风过程期间的沿岸潮位站的水位资料,对常用的拖曳系数模型对比分析研究,获得了适用于南海北部海区的拖曳系数方案。结果显示,拖曳系数方案采用Large and Pond(1981)模型在南海北部能够获得更加准确的风暴潮数值模拟结果。The northern South China Sea(SCS)is an area where storm surges occur frequently along the Chinese coast.A suitable drag coefficient parameter scheme can improve the accuracy of storm surge numerical simulation and has a profound impact on the prevention and reduction the influences of storm surges.Based on the data of the water levels of tidal gauges during two typhoon processes,this paper compares common drag coefficient models and obtains a drag coefficient scheme suitable for the northern SCS.The results show that the Drag and Pond(1981)model of the drag coefficient scheme can obtain more accurate results than others in the storm surge numerical simulations in the northern SCS.
