摘　　要：利用WAVEWATCH和SWAN嵌套模拟2007年8月墨西哥湾飓风迪安的波浪场。将QSCAT/NCEP混合风场与台风模型风场合成为背景风场。修改WAVEWATCH和SWAN嵌套接口以使WAVEWATCH和SWAN2种海浪预报模式能够有效地嵌套运行。利用WAVEWATCH和SWAN嵌套模拟飓风迪安的波浪场,采用浮标资料检验模拟结果,以验证WAVEWATCH和SWAN模拟的准确性及修改后嵌套接口的可用性。结果表明,修改嵌套接口之后模式运行平稳,2种模式的结果与浮标及高度计观测数据均基本吻合。嵌套模拟结果好于单纯使用WAVEWATCH模拟的结果,体现了利用2种模式嵌套模拟台风浪场的科学性。The wave during hurricane Dean in August 2007 is simulated using SWAN nested in WAVEWATCH. The wind field model of the asymmetry typhoon is combined with the QuickSCAT and NCEP blended wind to simulate the wind field of hurricane Dean. In order to make WAVEWATCH model and SWAN model nest with each other effectively, the WAVEWATCH nesting interface with SWAN is modified. The wave heights are simulated with SWAN nested in WAVEWATCH are verified with the actual data from buoy and altimeter to test the precision of simulating results and usability of modified nesting interface, and the results satisfactory, which indicates that it is properly to use two models simulating wave field.
