摘要
台风引起的强风和巨浪等灾害对山东半岛近海区域产生重大影响.本文通过使用第三代海浪模型SWAN,以Takahashi和Fujita.t公式嵌套计算得到的台风模型风场与ERA5背景风场合成后的风场作为模型的驱动场,对2019年第9号台风"利奇马"过程中的台风浪进行模拟.根据模拟结果对台风浪的有效波高、平均周期、波龄的分布情况进行数值分析,初步探索了台风"利奇马"过程中台风浪的空间分布特征,为山东省开展台风浪预警及防灾减灾提供技术支撑.研究结果具有一定的科学意义和应用价值.
Abstract
Disasters such as strong winds and huge waves caused by typhoons have a significant impact on the offshore area of Shandong peninsula.In this paper,by using the third-generation wave model SWAN,the driving field of the model was formed by ERA5 background wind field and the typhoon model wind field nested with Takahashi and Fujita.t formulas.The typhoon waves in the process of No.9 typhoon"LIKEMA"in 2019 were simulated.According to the simulation results,the distribu-tion of effective wave height,average period and wave age of typhoon wave was analyzed numerically,and the spatial distribution characteristics of typhoon wave during typhoon"LIKEMA"were prelimina-rily explored,which provided technical support for typhoon wave warning,disaster prevention and miti-gation in Shandong province.The research results have certain scientific significance and application value.
