Analysis of the Rijkoort-Weibull model

This report makes part of the KNMI Hydra project and it gives an overview of the reproduction and adjustments to the so-called "compound Weibull model for the description of surface wind velocity distributions"(Rijkoort, 1983). This model is used to calculate return levels of hourly wind speeds with high return periods (up to 10^4 years) at...

Probabilistic aspects of ocean waves

Background material for a special lecture on probabilistic aspects of ocean waves for a seminar in Trondheim. It describes long term statistics and short term statistics. Statistical distributions of waves, directional spectra and frequency spectra. Sea state parameters, response peaks, encounter probability.
