寒潮引起的江苏沿海风暴潮潮位分布规律研究
Study on Sea-level Distribution of Storm Surges Caused by Cold Wave in Coastal Areas of Jiangsu
摘要
Abstract
Based on the module Flow Model of MIKE21,and ECMWF reanalysis wind field,a numerical model coupling the astronomical tide and the storm surge in coastal areas of Jiangsu was established, and the sea levels of storm surges in Liyashan, Dafeng, Lianyungang and Xiangshui stations during the cold wave No. 141008 were calculated and verified. The verification re-sults showed that the model had a higher precision, and could be used for the calculation of storm surges caused by cold wave in coastal areas of Jiangsu. The most unfavorable combination of the highest astronomical tide level in 2002 with the cold wave No. 141008 was selected to study the distribution rule of sea level and anstau of storm surges in Jiangsu coastal areas when astronomi-cal tide occurred. The results indicated that:under such circumstances,the duration time of the anstau over 50 cm in the sea area of Liyashan station was close to 7 h,and the maximum anstau was about 100 cm. Under the influences of cold wave and gale,the anstau in the inshore sectorial areas taking Jianggang or Liyashan as centre was obviously higher than that in other neighboring sea areas, and it could reach 1.5 m or even higher.关键词
