| 摘 要： | 本文对海-气边界层波致风机制的相关理论进行了阐述,并利用ERA-40再分析资料给出了太平洋谱峰速度、波龄、波陡等描述涌浪和波致风机制物理量的年际和季节空间分布特征。分析表明:东太平洋赤道地区等海域涌浪速度最大且涌浪由南向北传播明显;太平洋波边界层高度基本呈现出东高西低的分布形势;波致风机制主要发生在赤道热带海域,北半球夏季波致风机制偏强,冬季偏弱,南半球反之;北半球北部海域夏季更易发生波致风机制,赤道附近海域相反;南海为风浪与涌浪组成的混合浪,对其波候等相关研究有必要分开进行讨论。

| Abstract: | The interannual and season spatial distribution of the peak phase speed of the wave, wave age, wave slope etc, which described for swell and wave-driven wind regime are given by the ERA-40 reanalysis data. The swell speed is the largest in the eastern Pacific equatorial region and other sea, and the propagation from south to north is obvious. The wave boundary layer (WBL) height in the Pacific Ocean shows the distribution situation with the higher in east and lower in the west. The wave-driven wind regime occurs mainly in the equatorial tropical seas, which is stronger in summer and weaker in winter in the northern hemisphere, but that in southern hemisphere is contrary. The northern seas of the northern hemisphere are more prone to the wave-driven wind regime in summer, while the seas near the equator are opposite. The waves in South China Sea is mixture waves of wind waves and swell, therefore it is necessary to discuss separately for the wave climate research. |
