摘要：

利用美国NOAA/NCEP开发的海浪数值模式WAVEWATCHⅢ。以每天4次的NOAA/NCEP再分析风场资料为输入,模拟了2004年8月8~12日西北太平洋海域的0414号“云娜”台风引起的海浪。通过分析TOPEX/Poseidon(以下简称T/P)高度计的星下轨迹浪观测资料和WAVEWATCHⅢ模式后报的有效波高大小,可以看出模式能够较好地模拟台风浪。

A full-spectral third-generation ocean wind-wave model WAVEWATCH,whichhas been developed at the Ocean Modeling(NCEP),is used to simulate the typhoon waveheighes during August 5~15,2004 with wind input of NCEP re-analysis data 4 times dailyin the Northwest Pacific Ocean.The significant wave heights(SWH) from WAVEWATCHmodel and TOPEX/Poseidon(T/P) altimeter data under the scan points in the NorthwestPacific Ocean for the August 8-12,2004 are compared.The temporal variation of SWHsfrom WAVEWATCH is generally consistent with that form T/P.
