| 摘 要： | 收集、整理、分析1949年以来广东省10个典型验潮站的近500站次台风风暴潮过程,开展了广东省台风风暴潮和超警戒风暴潮时空分布特征研究。结果表明:广东省台风风暴潮主要发生时间为7—9月,其中7月最多、9月次之,雷州半岛东岸无论发生次数还是强度都明显偏多、偏强,其次为阳江;风暴潮灾害则主要发生在7—10月,以7月最多;风暴潮灾害频发区依次为珠江口、雷州半岛东岸、阳江和汕头,风暴潮灾害严重区依次为汕头、阳江和雷州半岛东岸,阳江和雷州半岛东岸为风暴潮灾害频发区和严重区。选取受台风风暴潮影响频繁和严重的典型区域阳江市。利用业务化的台风风暴潮模式开展了不同等级台风影响下阳江市的最大风暴潮风险研究,中心最低气压为970hPa的台风在最有利路径下产生的风暴潮为185cm,约20a一遇,940hPa的台风产生的风暴潮为310cm,约为500a一遇。

| Abstract: | The characteristics of temporal and spatial distribution of storm surge in Guangdong Province are studied by historical storm surge. The result indicate that most of storm surge occurred in July and September. The frequency and intensity of storm surge in Leizhou Island are higher than other places in Guangdong Province. The main storm surge disaster occurred from July to October,the districts effected seriously by storm surge are Yangjiang and Leizhou Island. In addition,a study on storm surge hazard research of Yangjiang has been carried out,the result show storm surge effected by a typhoon with central pressure of 970 hPa and 940 hPa is 185 cm and 310 cm respectively. |
