Evaluation of the Seasonal Pattern of Wind-Driven Waves on the South-Southeastern Brazilian Shelf
The focus on renewable energy sources on the last few decades has pushed studies on wave energy availability. In this sense, this study aims to determine annual characteristics of the wave climate on the South-Southeastern Brazilian Shelf (SSBS) to improve the comprehension of the Brazilian wave climate, as well as, to give an insight on the more energetic coastal spots in this area. To accomplish that, the sea state model TOMAWAC was used to simulate 18 years of wave conditions on the SSBS which were later converted to a single year, representative of the Brazilian wave climate. The results showed a strong annual pattern of steadier sea state in summer and spring and a more agitated one in autumn and winter. The results also showed that in the Santa Marta cape, the seasonal wave power oscillates between 8 and 11 kW/m, and at Ilhabela, between 7 and 11 kW/m. At the Farol island, on the other hand, the seasonal wave power varies around 11 and 19 kW/m, yielding much more energy but, at the cost of an extremely higher variation throughout the year.
