基于第三代海浪数值模式WAVEWATCH-Ⅲ,以QuikSCAT/NCEP混合风场为驱动场,得到南海1999年8月~2009年7月的海浪场,分析了近10年南海的波候及波浪能特征,为波浪发电的选址提供参考。研究发现:南海的海浪场、海表风场受季风影响显著,海浪场与海表风场具有较好的对应关系,尤其体现在南海南部海域;南海的海表风场、海浪场与nino3指数存在显著的负相关;南海极值风速、极值波高的大值区分布于南海北部海域;南海蕴藏着较丰富的波浪能资源,年均值能流密度在4~20kW/m,大部分海域2kW/m以上能流密度出现频率在70%以上,且大部分海域能流密度的变异系数在0.4以内,稳定性较好,利于波浪能的开发与利用。
Based on WAVEWATCH-Ⅲ and the QuikSCAT / NCEP mixed wind field, the wave field in the South China Sea from August 1999 to July 2009 was obtained. The waveforms and wave energy characteristics of the South China Sea in recent 10 years were analyzed , Provide reference for the location of wave power generation. It is found that the sea surface wind field in the South China Sea is significantly affected by the monsoon, and the sea surface wind field has a good correspondence with the wind field, especially in the southern South China Sea. The sea surface wind field, the sea surface field and the nino3 index There is a significant negative correlation between the South China Sea and the South China Sea. The large value area of the South China Sea extreme value wind speed and extreme wave height is located in the northern South China Sea. The South China Sea is rich in wave energy resources. The average annual energy flux density is 4 ~ 20kW / m, The energy flux density above 70% is above 70%, and the coefficient of variation of energy density in most of the sea areas is less than 0.4. The stability is good, which is good for the development and utilization of wave energy.
