根据经验风场与NCEP再分析风场的优缺点,采用两者相叠加的方式构造了一种叠加风场,与实测风速资料对比验证显示该风场精度较高。以叠加风场数据为输入,采用WAVEWATCH Ⅲ模式对南海海域有显著影响的8场台风进行计算,结果显示叠加风场计算南海台风浪具有较高的精度和可靠性。
A superimposed wind field is constructed using empirical wind fields and NCEP reanalyzed wind fields from the advantages and disadvantages of the two,and the simulation result is good compared with the real wind field data.Eight typhoons greatly affecting the South China Sea is simulated using WAVEWATCH Ⅲbased on the superimposed wind field data,the superimposed wind field has shown higher accurate and more reliable in simulating typhoon-induced waves.
