Modelling Mean Wave Direction Distribution
With The Von Mises Model
Author(s)
J. L. Vega & G. RodrÃguez
Abstract
This paper presents the probabilistic modelling of the mean wave direction
derived from directional spectral analysis of waves recorded by directional
buoys. The analysis is performed on the mean wave direction in terms of the
climatic season, the sea state severity and the period of the dominant waves. The
usefulness of the von Mises theoretical models to describe the empirical kernel
density estimates is examined. It is observed that the single von Mises theoretical
model results are useful to fit the observed distribution only for moderate and
severe sea states while the mixture of two von Mises distributions enhances
significantly the degree of fitness.
Keywords: wave modelling, mean wave direction, kernel density estimation,
circular variables, von Mises distribution, von Mises mixtures.
