摘要
利用ERA．40海表101TI风场驱动第三代海浪数值模式（WAVEWATCH-Ⅲ，简称WW3），得到南海-北印度洋1957年9月～2002年8月的海浪资料，计算该海域的波浪能，分析波浪能流密度的四季分布特征、不同能级出现的频率及波浪能流密度的稳定性，为海浪发电、海水淡化等选址提供依据。研究发现，南海-北印度洋海域蕴藏着较为丰富的波浪能：（1）南海-北印度洋大部分海域的年平均波浪能流密度在2kW／m以上，大值区位于南海、孟加拉湾、索马里附近海域。（2）南海=北印度洋海域波浪能流密度大于2kW／m和大于4kW／m出现的频率都较高。（3）南海-北印度洋的波浪能流密度具有较好的稳定性，春季、秋季、冬季的稳定性好于夏季，南海的稳定性好于北印度洋。
The third-generation wave model WAVEWATCH-Ⅲ（WW3） was used to simulate the wave from 1957 to 2002 with the input of ERA-40 wind data in the South China Sea and Indian Ocean. The primary characteristics of wave energy were calculated. The South China Sea and North Indian Ocean were rich in wave energy; We found （1） wave energy density in most areas was larger than 2 kW/m, large areas located in the South China Sea, Bengal- ese Gulf and waters around Somali; （2） frequency of wave energy density 〉 2 kW/m was high; （3） the wave energy density in the South China Sea and North Indian Ocean had good stability, the stability in spring, autumn and winter being better than that in summer and the stability in the South China Sea being better than that in the North Indian Ocean.
