| 摘 要： | 海面风场在海浪模拟研究和预报中起着关键性的作用,再分析风场数据可为海浪模式提供长时间的大范围、高时空分辨率海面风场。利用日本浮标站资料和卫星高度计资料对再分析风场QuickSCAT/NCEP(Q/N)混合风场和ERA风场进行验证分析,并利用WAVEWATCH-Ⅲ模式进行连续12个月的数值模拟试验。对比风场和计算得到的海浪场得出结论:在风速较小的时候,ERA和Q/N风场较实测风场大,在风速较大的时候,ERA和Q/N风场较实测风场小;ERA风场模拟浪高较浮标观测波高偏小;Q/N混合风场模拟的浪高更接近实测浪高。 |

| Abstract: | Reanalysis wind data can provide a large scale and high spatial-temporal resolution sea surface wind field,and plays a pivotal role in the wave simulation and forecast.Based on the wind field data from QuickSCAT/ NCEP(Q/N) and ERA validated by the data from Japanese buoy station and and satellites altimeter data,the waves are simulated for 12 months by the WAVEWATCH-Ⅲ model.The results show as follows: wind data from ERA and Q/N are stronger than the actual wind when wind speed is low,but weaker when wind speed is high;the wave height simulated by ERA wind is smaller than that from buoy data;the wave height simulated by Q/N wind is more close to the actual wind. |
