波能的统计特性在很大程度上取决于波的特性。当没有足够的可用波高时，波能转换器无法产生能量。因此，最小波高的重现期和风险值的评估成为波浪能研究的重要内容。本文提出了一种用于海洋波浪应用的最小波高时间指数。持续性在收益期和风险的计算中起着重要的作用。虽然忽略序列独立性使计算变得容易，但它会导致高估真实的状态。在本文中，回报期和风险值相互比较，考虑到独立和依赖的情况。该研究的应用实现了位于太平洋和墨西哥湾的台站。
The statistical behavior of wave energy at a site strongly depends on the wave characteristics. Wave energy converters fail to produce energy when there are no sufficiently available wave heights. Hence, evaluation of return periods and risk values of the minimum wave height becomes important for wave energy studies. A time index representing the minimum wave height is proposed here for ocean wave applications. Persistence plays a significant role in the calculation of return period and risk. Although ignoring the serial independence makes calculations easy, it leads to overestimations of the real status. In this paper, return periods and risk values are compared with each other by taking into consideration independent and dependent situations. Application of the study is achieved for the stations located in the Pacific Ocean and Gulf of Mexico.
