摘要
针对传统统计方法难以准确描述波浪联合分布特征的问题,结合波浪物理意义及相应统计参数,提出了可描述波浪要素联合分布的概率模型.首先给出了波高、周期和波向的边缘分布及联合分布理论概率模型,然后利用实测数据进行了验证.结果表明,本模型可有效重现波浪条件.
It is difficult to tional statistical methods. So,a reproduce the joint statistics of joint probability distribution m bining the physical significance and the statistical parameters the real wave conditions by using the tradi- odel of wave elements was proposed by corn- of waves. In the first part, the marginal and joint probability distribution of wave height ,wave period and wave direction were presented in sequence. In the second part, the joint probability distribution model was verified based on the measured data. Results imply that the in-site wave conditions can be reproduced with high accuracy.
