摘要：

风暴潮是中国沿海最严重的自然灾害之一。对1950—2003年中国沿海67个站点的风暴潮增水数据进行了统计和分析,得到了中国沿海风暴潮增水的时空分布。研究发现,无论在频次还是在强度上,东南沿海都是中国沿海风暴潮灾害最严重的区域,风暴潮强度集中在Ⅲ级、Ⅳ级和V级,其中长江口和杭州湾风暴潮增水较大。此外,风场路径和天文潮潮汛对风暴潮增水的影响显著;以定海站点为例,在125°E以西转向的热带气旋对该站点风暴潮增水影响最大,风暴潮增水的极值时刻绝大多数在大潮时刻,潮汐时刻多在天文低潮前后。研究结果可为风暴潮风险评估和防灾减灾提供参考。

Abstract:

Storm surge is one of the most serious natural disasters along the coast of China. The temporal and spatial distribution of storm surge in China’s coastal areas was obtained by analyzing the storm surge data of 67 stations from 1950 to 2003. It is found that the southeast coast of China is the region with the most serious storm surge disasters in terms of frequency and intensity, and the intensity of storm surges is concentrated in Ⅲ, Ⅳ, and Ⅳ levels. The storm surge in the Yangtze Estuary and Hangzhou Bay are relatively large. Moreover, the path of the wind field and the astronomical tide have a significant impact on the storm surge. Taking Dinghai station as an example, the path of the tropical cyclone turning to the west of 125°E has the most significant impact on the storm surge and most of the occurrence time of peak surge is around spring tide and before and after the astronomical low tide. The results can provide a reference for storm surge risk assessment and disaster prevention and mitigation.

Key words: storm, water level surge, coast of China, temporal and spatial distribution
