Influence of an Atypical Value in the Extreme Wave Analysis Using Non-Stationary GEV Models | Chapter 11 | Emerging Issues in Science and Technology Vol. 1

In the present study an extreme value analysis of maximum significant waves recorded at a buoy located in the Pacific Ocean was carried out by including/excluding an atypical extreme wave height.  The analysis was carried out using a non-stationary Generalized Extreme Value (GEV) model, which incorporates the monthly seasonality of maximum observed values in time increments; the maximum significant wave behavior was parameterized using harmonic functions for the distribution measures. A single buoy was considered for the scope of this paper. In the study differences in the seasonality effect were found due to the exclusion of the atypical value, which is especially significant because it occurred in a season with supposedly low wave heights values.
