中国沿海40年台风风暴潮特征研究
Characteristic analysis of tropical storm surges affecting the coastal area of China in the past 40 years
摘要
Abstract
Statistical analysis of temporal and spatial characteristics of tropical storm surges(TSS)has been conducted for more than 400 events affecting the coastal area of China in 1980-2019.It is shown that the number and variation amplitude of severe TSS event with maximum residual value exceeding 2 meters have an increasing trend during the past 40 years,especially in the past decade.Meanwhile,the number of weak TSS event has increased.The annual extreme TSS also increased in the past 40 years.In the past 40 years,nearly 50％ of the typhoons which cause extreme surges appeared in the last decade,which is likely to indicate that the strong typhoons affecting the coastal area of China are increasing.Over-warning-threshold TSS events occurred in the southern Zhejiang and northern Fujian Province,but number of extreme surges in these two regions is smaller than that in the Pearl River Estuary and the East Bank of Leizhou Peninsula,where own the highest risk of TSS hazard.关键词
