Ponce de Leon, S., Gomez, J., Sanchez-Arcilla, A. e Guedes Soares, C. (2014), “Comparison of extreme storms in the North Atlantic and Mediterranean”, 3rd IAHR Europe Congress, 14-16 Abril, Porto, Portugal
A spectral characterization of two extreme storms is made using numerical wave hindcasts produced with the WAM model and wave buoys records in two different basins: the North Atlantic Ocean and the Mediterranean Sea. The results show that despite the different magnitude of the storms the directional wave spectra had similar distribution over frequencies and directions in both cases. All the single peaked spectra associated with the Quirin storm in the North Atlantic show a maximum spectral peak around 0.05 Hz (about 20 seconds). For the storms in the Mediterranean, having lower wave energy, the swell absolute peak was found at a frequency around 0.08 Hz (12.5 seconds). The North Atlantic storm had longer duration (in average 6-7 days) than the Mediterranean storms (4-5 days). The maximum peak period in the North Atlantic was higher than 20 seconds in contrast with the 12.5 seconds maximum of the Mediterranean storms. The lowest directional spreading associated to the extreme values of the Hs (significant wave height) was found to be similar in both basins (24º).
