Development and Application of An Operational Tide and Storm Surge Prediction Model for the Seas around Taiwan

Abstract：Storm surges are abnormal rises in sea level along coastal areas and are mainly formed by strong wind and atmospheric depressions.When storm surges coincide with high tide,coastal flooding can occur.Creating storm surge prediction systems has been an important and operational task worldwide.This study developed a coupled tide and storm surge numerical model of the seas around Taiwan for operational purposes at the Central Weather Bureau.The model was calibrated and verified by using tidal records from seas around Taiwan.Model skill was assessed based on measured records,and the results are presented in details.At 3-minute resolution,tides were generally well predicted,with the root mean-square errors of less than 0.11 m and an overall correlation of more than 0.9.Storms (winds and depressions) were introduced into the model forcing by using the parameter typhoon model.Five typical typhoons that threatened Taiwan were simulated for assessment.The surges were well predicted compared with the records. 作者： Author： YU Hao-cheng  YU Chia-shun 作者單位： Department of Marine Environment and Engineering, National Sun Yat-Sen University, Kaohsiung 804, China 期 刊： 中國海洋工程（英文版）   ISTICEISCI Journal： China Ocean Engineering 年，卷(期)： 2011, 25(4) 分類號： U674.941 Keywords： storm surge    parameter typhoon model    wind    depression    機(jī)標(biāo)分類號： TP3 P7 機(jī)標(biāo)關(guān)鍵詞： Prediction Model    Storm Surge    Tide    Application    numerical model    storm surge    surge prediction    coastal areas    strong wind    correlation    sea level    tide    typical    results    Central    errors    study    skill    based    task 基金項(xiàng)目： Development and Application of An Operational Tide and Storm Surge Prediction Model for the Seas around Taiwan[期刊論文]  中國海洋工程（英文版） --2011, 25(4)Storm surges are abnormal rises in sea level along coastal areas and are mainly formed by strong wind and atmospheric depressions.When storm surges coincide with high tide,coastal flooding can occur.Cr...
