| Resumen : | In this work we consider the evolution of power spectra of waves
during a period of one year. Soukissian and Samalekos (2005) have
proposed a segmentation method for significant wave height based on
determining periods of stability, increase and decrease using time-series
techniques. The second segmentation method is based on the mean
value over a moving window, and uses a fixed-width band to determine
the change-points in the register. We compare both segmentation
methods for several spectral characteristics and give a statistical
analysis of duration and intensity of sea states in each case. |
