A Stochastic Model in Space and Time for Monthly Maximum Significant Wave Height

Abstract

It is important to take severe sea state conditions into account in ship design and operation and there is a need for stochastic models describing the variability of sea states. These should also incorporate realistic projections of future return levels of extreme sea states, taking into account possible long-term trends related to climate change. The stochastic model presented herein is such a model. The model has been fitted by significant wave height data for an area in the North Atlantic ocean and it aims at describing the temporal and spatial variability of significant wave height in this area. The model will be outlined and the results obtained by using monthly maximum data will be discussed.
