Aktis has software with several distributions including the 3-parameter Weibull distribution, which we consider to be the most appropriate for most metocean phenomena. Our preference for the Weibull distribution is based on discussion in the Ph.D. thesis by C.F. de Valk in which he argues that the tails of distributions we encounter in meteorology and oceanography frequently reduces to the Weibull shape. We are also developing the application of the Log-GW distribution which de Valk recommends as the most generally applicable distribution for Metocean data.
