Petrov, V., Lucas, C. and Guedes Soares, C. (2019), “Maximum entropy estimates of extreme significant wave heights from satellite altimeter data”, Ocean Engineering, Vol. 187, pp. 106205 (12 pgs)
The performance of the Maximum Entropy method (MaxEnt) is compared to the one of the Generalized Pareto distribution (GPD) in extrapolating the extreme wave climate over the northern part of Atlantic Ocean, based on a twenty-year dataset of satellite altimeter measurements of significant wave height. Both methods are employed on peaks over threshold (POT) samples, which consist of medians above a given threshold value calculated for each satellite passage, over a grid of points of 1º latitude x 1º longitude. Additionally, the generalized extreme value distribution (GEV) employed on annual maxima data has been used as a reference model. The results indicate that the MaxEnt is significantly less sensitive to the threshold level than the GPD, that is, to the variation of the sample size, when producing extreme values of significant wave height.
