ABSTRACT
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.
