Ferreira, J.A. and Guedes Soares, C. (2002), “Modelling Bivariate Distributions of Significant Wave Height and Mean Wave Period”, Applied Ocean Research, Vol. 24, Issue 1, pp. 31-45

The use and scope of long-term distributions of sea-state parameters are discussed. The approach of fitting bivariate distribution functions as a way of modelling the joint behaviour of significant wave height and mean zero-upcrossing period is also discussed, being suggested that adopting parametric models is not always essential. The current approach to the use of the data and the fitting of models and in studies of marine structures is analysed; an alternative approach is sketched. The conclusions about long-term distributions are reinforced by the analysis of some data. In view of the statistical variability that exists in data sets from different years, it is concluded that models describing significant wave height and mean zero-upcrossing period (and sea-state parameters in general) in terms of frequency of occurrence should include the concept of random population. A bivariate density function is proposed for summarising significant wave height and mean zero-upcrossing period data jointly.
