Extremesea condition element estimation of binomial-generalized Pareto compound model
Based on the compound extreme value distribution theory,binomial-generalized Pareto com-pound extreme value distribution model based on short-term observation samples was constructed and applied to the prediction of extreme sea condition elements.The results showed that the binomial-gen-eralized Pareto compound extreme value distribution model had good fitting effect,could reasonably re-flect the long-term probability distribution characteristics of extreme sea conditions and made up for the defect of traditional methods need long-term raw sea condition data.The simulation results were simi-lar with the results using long-time data,the Gumbel model and the lognormal model,and had strong applicability in the prediction of wave height.
