摘要： 本文利用南海北部某海区长达2年的海上实测风速数据，开展了不同风速条件下的多种风谱模型适应性分析。结果表明, 在南海北部观测区域，与其它风谱模型相比，API规范推荐的风谱模型与实测的风谱较一致。然而在大风条件下，API风谱在低频区存在谱值低估的现象。利用实测数据，对API推荐风谱模型的参数进行了修正，修正后的风谱模型在低频区的谱值有改进。本文的研究成果为南海海洋工程设计提供参考，同时也为南海风谱研究提供支持。

Abstract: In this paper, 2-year measured wind speed data in the Northern South China Sea is applied to analysis the adaptability of various wind spectrum models under different wind speeds. The results show that the wind spectrum model recommended by API coincides better with the observed wind spectrum in the northern South China Sea. While in the high wind speed condition, the API spectrum value is lower than the measured wind spectrum value in the low frequency region. Meanwhile, the measured data is used to modify the parameters of API wind spectrum model, and modified API wind spectrum is improved in the low frequency region. The research results of this paper can provide a reference for ocean engineering design in the South China Sea, and give a support for the study of wind spectrum in the South China Sea.
