基于埃尔米特转换高斯模型的波浪统计分析

The probability distributions of wave characteristics from three groups of sampled ocean data with different significant wave heights were analyzed using Hermite transformed function estimated by parameter methods. The marginal wave characteristic distribution and the joint density of wave periods, wave heights, and local extreme were calculated using the Hermite transformed function, with the results and accuracy of both transformations presented here. The crest and trough marginal distributions and extreme value joint densities of the Hermite transformed models depart from Gaussian process with higher ocean conditions. The Hermite model for the calculation of the wave crest and trough height distributions was shown to provide good agreement with real ocean data. It can be seen that our work will help in the determination of the most appropriate transformation procedure for the prediction of extreme values.
