摘　　要：基于ELCIRC模型建立了适用于珠海市海域的风暴潮模型,以1713号台风“天鸽”路径为基础,通过改变台风入射角、台风登陆点、台风移速等方式构建登陆或者影响珠海市的台风路径,并进行风暴潮数值模拟计算,分析珠海市沿海风暴潮特征。结果表明:改变台风入射角时,珠海市沿海不同岸段的风暴潮将出现较大差异性;距离台风中心约15~100 km且位于台风右半圆的沿海地区将是风暴潮的重灾区;在珠海市的香洲区和斗门区沿岸,风暴增水总体随着台风移速变慢而呈现增大的趋势,但金湾区的情况则较为复杂,当台风移速为15~30 km/h时,在沿着台风“天鸽”的移动路径上会产生较强的风暴潮过程。Based on the ELCIRC model and Typhoon"Hato"(1713),a series of typhoon tracks landing or affecting Zhuhai have been conducted by changing incident angle,landfall location or moving speed of the typhoon.Feature of coastal storm surge in Zhuhai are studied by the ELCIRC numerical simulation.The results show that large differences in maximum storm surge exist in different coastal areas of Zhuhai when the incident angle is changed.Coastal areas are severely impacted when locate in the right half circle of the typhoon with its distance to the typhoon center being 15~100 km.The maximum storm surge increases along with the slows down of the moving speed of the typhoon in Xiangzhou district and Doumen district,however in Jinwan district,strong storm surge occurs along the typhoon track when the moving speed of the typhoon is 15~30 km/h.
