摘要: 风暴潮是中国沿海最严重的自然灾害之一。本文基于1950年到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值较大。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125ºE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. Based on the statistics and analysis of the storm surge data of 67 stations along the coast of China from 1950 to 2003, the temporal and spatial distribution of storm surges. The study found that no matter in terms of frequency or intensity, the southeast coast of China is the region with the most serious storm surge disasters along the coastal areas, and the intensity of storm surges is concentrated in Ⅲ, Ⅳ, and Ⅳ levels. Besides, the amplitudes of the storm surge in the Yangtze Estuary and Hangzhou Bay are relatively large in the study area. Moreover, the path of the wind field and the astronomical tide have a significant impact on the surge levels. Taking the Dinghai station located at the southeast coast of China as an example, the paths of the tropical cyclone turning to the west of 125ºE have the most significant impact on the storm surge and most of the occurrence time of peak surge level is around spring tide and before and after the astronomical low tide. The results can provide a reference for storm surge risk assessment, disaster prevention, and mitigation.

Key words: storm surge, coast of China, temporal and spatial distribution, astronomical tide
