摘要
以台风"梅花"为例,采用QSCAT/NCEP再分析风场资料和捷氏台风经验模型构造混合型台风风场,以此作为驱动条件,利用MIKE21波浪谱模型对江苏沿海近岸台风浪进行数值模拟,并针对潮位变化对模拟结果的影响进行对比分析。结果表明,该模拟方法可以较好地复演台风浪发展的整个过程,而考虑潮位变化的影响有助于台风浪模拟精度的提高。
This paper simulates the waves induced by the typhoon ＇Muifa＇. With the driven wind conditions generated by incorporating the Jelenskin typhoon model and QSCAT/NCEP bended wind, a typhoon wave model along Jiangsu coast is developed based on the MIKE21 spectral wave model, and a comparative analysis of simulation results with and without the effect of tidal water level is conducted. The results show that, the simulation model used in this paper can reasonably reproduce the features of entire process in the development of typhoon waves, and the accuracy of typhoon waves can be improved by considering the change of tidal water level.
