Resumo: In this study, 30 years of sea state data reconstructed by means of the wave generation model WW3 for the oceanic area were used to investigate wave regimes in southern Brazil. By applying a splitting routine (WW3´s Wsplit) to the spectra generated by WW3, each sea state was decomposed into its primary and secondary wave systems. Histograms of wave height and period against direction of incidence constructed for the 30 year period, showed that the region possesses two different characteristic wave systems: seas from the East quadrant and swell from the South quadrant. In a more detailed characterization, histograms constructed with 30 years of data were compared with annual histograms and the results were used to identify the year that best represented the totality of the data. For this representative year identified, the technique of clusters analysis was applied and six typical scenarios of wave system in the Southern RS state were found. (A) Easterly swell, (B) Easterly sea, (C) Westerly sea, (D) Southerly sea, (E) Southerly swell e (F) SouthEasterly ground swell.

Aplicando-se a rotina Wsplit do próprio modelo numérico aos espectros calculados, cada estado de mar foi decomposto nas suas componentes primárias e secundárias. Os histogramas de Altura e Período de ondas por direção de incidência destes 30 anos de dados evidenciaram dois sistemas de ondas bem característicos da região: vagas do quadrante Leste e ondulações do quadrante Sul. Para uma caracterização mais detalhada, os histogramas feitos a partir dos 30 anos de dados foram comparados com histogramas anuais no intuito de se identificar o ano que melhor representava a totalidade dos dados. Para o ano identificado, aplicou-se a técnica de agrupamentos e seis cenários característicos de agitação marítima para a região Sul do estado do RS foram encontrados: (A) ondulação de Leste, (B) vagas de Leste, (C) vagas de Oeste, (D) vagas de Sul, (E) ondulação de Sul e (F) ondulação distante de Sudeste.Universidade Federal do Rio Grande2012-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.furg.br/vetor/article/view/2568VETOR - Journal of Exact Sciences and Engineering; Vol. 21 No. 1 (2011); 91-109VETOR - Revista de Ciências Exatas e Engenharias; v. 21 n. 1 (2011); 91-1092358-34520102-7352reponame:Vetor (Online)instname:Universidade Federal do Rio Grande (FURG)instacron:FURGporhttps://periodicos.furg.br/vetor/article/view/2568/1384Copyright (c) 2014 VETOR - Revista de Ciências Exatas e Engenhariasinfo:eu-repo/semantics/openAccessRomeu, Marco Antônio RigolaFontoura, José Antônio ScottiMelo Filho, EloiMachado, Vanessa Barbosa2023-03-22T15:42:44Zoai:periodicos.furg.br:article/2568Revistahttps://periodicos.furg.br/vetorPUBhttps://periodicos.furg.br/vetor/oaigmplatt@furg.br2358-34520102-7352opendoar:2023-03-22T15:42:44Vetor (Online) - Universidade Federal do Rio Grande (FURG)false
