摘要
为研究"桑美"台风风暴潮的增水特征,基于POM海洋数值模式,建立包含福建省、浙江省、江苏省在内的天文潮与风暴潮耦合数值预报模型,并以此模型计算浙江省南部至福建省北部9个站点在台风登陆期间的增水过程。结果表明,9个站点的增水曲线表现出3种类型:标准型、波动型、随机型。距台风登陆点最近的站点表现为标准型,稍远为波动型,台风边缘处表现为随机型;鳌江站具有远超其他站点的最大增水,而这一现象是台风登陆点位置、鳌江站的特殊地形、风暴潮与天文潮耦合作用等多种原因所致。
A tide-surge coupling model based on the Princeton ocean model(POM) was established to study the features of a storm surge caused by Typhoon Saomai.The calculation area of the model contains Fujian,Zhejiang,and Jiangsu provinces.Processes of a storm surge at nine stations along the coast from southern Zhejiang Province to northern Fujian Province were calculated with this model.The results show that the storm surge variation curves at the nine stations can be classified as three types: the standard type,fluctuation type,and stochastic type.Standard curves generally occurred at stations that had the shortest distance from the typhoon landing site,fluctuation curves occurred at stations at a distance from the landing site,and stochastic curves occurred near the edge of the area affected by the typhoon.The Aojiang Station had the storm surge peak value,which was caused by various factors,such as the location of the typhoon landing point,the special topography of the station,and the coupling action between the storm surge and tide.
