MODELLING LONG-TERM DISTRIBUTIONS OF SIGNIFICANT WAVE HEIGHT

The problems involved with the use of parametric models to describe the long-term behaviour of the significant wave height are discussed. In particular, it is shown that the usual understanding of "good fit" does not ensure a good representation of the tails. The problem of defining a population and of choosing one sample for inferring the parameters of the distribution is discussed. In particular, the time-varying character of the data is illustrated. A new model of long-term distribution is proposed which accounts for this variability.
