The analyzing and summarizing of the storm surge caused by typhoon NO.6 (Prapiroon) in 2006

In 2006 the NO.6 typhoonPrapiroonlanded on a point between Yangxi and Dianbai of Guangdong Province.It brought serious economic loss for its huge wind,the very rough sea waves as well as strong rain for Guangdong,Guangxi and Hainan province coastal area.This article utilization hydrology statistics and meteorology knowledge on analyzing tidal level and the storm tide from Naozhou and Zhapo marine observation stations.Thus,certain relations between the typhoon and the storm surge are concluded that the typhoons’ landing position,wind power,the wind’s last time and waves would clearly prescribe the storm surge.The author has also discussed factors such as typhoon track and special terrain characteristic causes deriation between happening time of peak surges at tidal stations and typhoon landing time.This article through analyzes this typhoon the storm surge characteristic,may help to sum up experiences,and to improve the accuracy of storm surge prediction for the future.
