The extreme wind & wave climate in Atlantic Ocean will be investigated and future prognostics and long-term extreme quantiles will be estimated, using a regional approach. It involves a new methodology joining the stochastic extreme value theory with numerical simulations of the climate. A calibration of wind and wave reanalysis using satellite and buoy data focused on higher percentiles will generate the database for this study, of wind speed and significant wave height. Since the surface winds controls the wave spectra growth, a deep investigation of the storm tracks, patterns, associated statistics, and possible modifications due to climate change will be conducted. A statistical regionalization will define strategic locations with higher vulnerability, where the statistical modeling must be performed in more details and better resolution.
