摘　　要：根据1965-2016年间影响广西沿海的热带气旋资料和风暴增水资料,分析研究广西沿海风暴增水特征。结果表明:在时间分布上,广西沿海平均每年发生风暴增水过程1.8次,每年6-10月均有可能发生风暴增水,且集中在7-9月。在空间分布上,广西沿海风暴增水过程呈现出规律性:在不同路径热带气旋影响下,各观测站风暴增水均是先减水,后增水,最后逐渐回落至正常状态;观测站距离热带气旋登陆地点越近,其最大增水值越高;反之,其最大增水值越低。另外,还采用Pearson-Ⅲ型分布计算广西沿海不同重现期的高潮位值。The characteristics of storm surge along the coast of Guangxi is investigated in this study using the tropical cyclone and storm surge data from 1965 to 2016..The results show that storm surge occurs 1.8 times per year on average along the coast of Guangxi.Storm surge usually occurs between June and October,and occurs most frequently between July and September.In terms of spatial distribution,the process of storm water increase in Guangxi coast shows regularity:Under the influence of tropical cyclones with different tracks,the water level of all observation stations tends to increase at the beginning and decrease thereafter,which gradually returns to normal condition in the end.The closer the observation station is to the tropical cyclone landing location,the higher the water level of the maximum storm surge will be,and vice versa.In addition,the maximum water level of different return period along the coast of Guangxi is calculated using Pearson-III distribution in this paper.
