Estimate of the Wave Climate on the Most Energetic Locations of the South-Southeastern Brazilian Shelf

Article Preview

The wave energy availability has become a field of intensive research around the world. In this sense, this study aims to estimate the wave climate at the most energetic spots on the South-Southeastern Brazilian Shelf (SSBS). To achieve this goal, the sea state model TOMAWAC was used to simulate 18 years of wave conditions on the SSBS. The results showed that the sites at Santa Marta cape and Ilhabela are quite similar, with mean wave height of 1.4 m and period of 8.5 s along the climatological year. Farol island, on the other hand, showed higher averages, of 1.7 m and 8.9 s for wave height and period, respectively. The annual behavior of the wave parameters showed greater stability at Santa Marta cape and Ilhabela, and less at Farol island. The mean wave power yield at the Santa Marta cape and Ilhabela is nearly 10 kW/m and at Farol island, 15 kW/m. A wavelet analysis pointed that the most energetic events are those with periods of occurrence from 6 to 12 days, with the apex at 7 days. The wavelet analysis also showed that the most energetic spectrum is the one at Farol island, with 2.5 times the energy of the other locations at the period band of 7 days.
