| 摘 要： | 通过分析实验室风浪资料,研究风浪波高间的相关性以及波群中波高累积概率问题,发现风浪波高间相关性虽然主要发生在相邻波之间,但在隔1个波和隔2个波的波高间仍存在一定的相关性。谱宽度对波高间的相关性产生影响,但在相邻波、隔1个波和隔2个波情形下,谱宽度对波高间的相关性的影响方式不同。在相邻波情形下,谱宽度主要影响较大波高间的相关性,对各种高度波高间的总体相关性影响很小。而在隔1个波和隔2个波情形下,谱宽度对各种高度波高间的总体相关性有明显影响。根据实验结果提出含有波高相关因子的波群中多个波波高累积概率分布。

| Abstract: | The study is made on the correlation between wave heights and the accumulative probability of wave height in the wave group by analyzing wind wave data in the laboratory.It is found that the correlation between wave heights exists mainly in consecutive waves.However,in the case of waves separated by one or two waves correlation still exists.The correlation is influenced by spectral width.The effects of spectral width on the correlation are different in the cases of consecutive waves and waves separated by one or two waves.In the case of consecutive waves the effect of spectral width on the correlation is mainly in the high wave range.The effect on the overall correlation is very weak.In the case of waves separated by one or two waves,the effect of spectral width on the overall correlation is remarkable.A wave height accumulative probability distribution containing correlation parameter is proposed. |
