| 摘 要： | 根据1965—2009年间影响北海市沿岸的热带气旋资料和风暴增水资料,进行统计分析北海市沿岸的风暴潮特征。结果表明:北海市沿岸平均每年发生风暴增水2—3次,其中较大以上强度的风暴增水每年0.87次,严重以上强度的风暴增水每3年有一次;北海市沿岸每年4—11月均有可能发生风暴增水,且集中在7—10月,尤以9月最多。影响北海市沿岸的热带气旋主要以西北行路径为主,且多是穿过雷州半岛或海南岛后在越南沿海登陆,此种情况下,风暴增水曲线表现为周期性波动。另外,本文还采用Pearson-Ⅲ分布和Gumbel分布来估算风暴增水频度,得出北海市沿岸不同重现期的高潮位值。

| Abstract: | Based on the tropical cyclone storm surges data from 1965 to 2009 in the Beihai city,the characteristics of storm surges is studied along the coastal region.The results show that there are 2—3 times storm surges occured annually along the Beihai coast,whereas the frequency of serious storm surge is 0.87 times per year and a severe storm surge occurs once every 3 years.The Beihai city are likely to have storm surges from April to November in each year,especially more in 7—10 months and most in September.The tropical cyclones influencing the Beihai coast is mainly in the northwest line of the path,and mostly through the Leizhou Peninsula or along the coast of Hainan Island before landing in Vietnam.Under such circumstances,the storm surge curve showed periodic fluctuations.In addition,the frequency of storm surge is estimated based on Pearson-Ⅲ distribution and the Gumbel distribution.The repcurrence interval of high tide is obtained along the Beihai coast. |
