Peak period statistics associated with significant wave heights by conditional mean functions of the distributions
This study uses the 21 years of daily maximum significant wave height and associated peak period distributions for winter and summer of a test site in the North Atlantic Ocean. Conditional mean functions of generalized Pareto, three-parameter Weibull and Erlang distributions are used to model the average conditional exceedances of peak periods associated with significant wave heights. The method of L-moments is used for model estimation. Mean maximum peak periods and most probable maximum peak periods are also computed from the data and estimated from the models. A general formula based on order-statistics is provided for estimation of average of one-third the highest wave periods and an expression is derived from generalized Pareto distribution.
