| 摘 要： | 通过分析大量的外海浮标观测资料 ,发现波龄和无因次波高之间存在非常好的相关性 ,自然海况下的波浪场满足 3/ 5指数律 ,其波龄可达到几十 ,远远超过风浪波龄的上限 1 .4,说明波浪组成波之间波 -波共振非线性相互作用是波浪内部结构的主要调节机制 ,使波高和周期之间具有很好的相关性。

| Abstract: | By using observational data from buoys, it is found that the wave age correlates well with the nondimensional wave height for ocean waves in natural conditions,which are in accordance with the 3/5-power law. The estimated wave age is much greater than 1.4, which is regarded as the maximum value for wind waves. It is shown that the dominating mechanism of the internal structure of ocean waves is nonlinear wave-wave resonant interaction among the components of ocean waves, which adjusts the correlation between wave height and wave period. |
