Abstract

Abstract

Application of Bayesian statistical method to the analysis of directional spectrum of wind waves is presented in detail.It is pointed out that the difference of prior distributions has no influence on the estimated results,and there is some speciality for even distribution due to its corresponding to maximum entropy principle.The effectivity of Bayesian statistical method on the estimation of bimodal distribution is shown by numerical simulation.Through the analysis of Black Sea data,it is demonstrated that whether or not a bimodal distribution depends strongly on the estimating methods and the truthfulness of bimodal distribution obtained by the maximum likelihood method is doubted.A possible physical explaination for emergence of bimodal distribution is presented finally.
