“…This is relevant to all topics in coastal engineering. The final paper (by Teles, Pires-Silva, & Belo-Pereira (2012)) in coastal hydrodynamics confirms this point. The SWAN model is used to estimate the wave field on an open sandy beach on the west coast of Portugal, considering different parameters and their effects.…”

“…Da mesma forma como ocorre com o processo de passagem descrito para as malhas externa e intermediária, o modelo SWAN é novamente rodado, para fornecer os parâmetros de agitação marítima junto à costa. Essa estruturação em malhas encaixadas fornece melhores resultados e reduz os erros que poderão resultar da inexistência de condições de fronteira nos limites laterais (este e oeste) do domínio exterior (PIRES SILVA et al, 2000;TELES et al, 2012;ÂNGELO, 2012). Para o espaço espectral foi defi nida a resolução direcional de  = 4º (valor aconselhado pelo manual do SWAN na presença de swell) cobrindo 360º em direção, e um intervalo de frequência de  = 0.04 Hz.…”

Resumo:Este artigo apresenta os resultados da aplicação do modelo numérico Simulating Waves Nearshore (SWAN) com análises comparativas das medidas obtidas a partir dos resultados de modelagem e de medições durante as campanhas de campo em 2010 e 2012 no Litoral Setentrional do Rio Grande do Norte (NE do Brasil). O objetivo principal do presente estudo foi aplicar e validar o modelo numérico SWAN na determinação do clima de ondas, avaliar seus pontos fortes e limitações para a região de interesse. Os dados de campo realizados em dois pontos próximo da costa em profundidades de 3 m (PT_1) e 6 m (PT_2) por meio do uso de dois adcp: AWAC e AQUADOPP. Os dados adquiridos com estes equipamentos foram processados e permitiram a realização de análises espectrais de altura signifi cativa, HS (m), período médio, Tmed (s), e direção média, DIR (º). Para a implementação do modelo SWAN foram empregados para as condições de contorno os dados de agitação a partir do modelo de 3ª geração de escala oceânica

Adjustment of the summertime marine atmospheric boundary layer to the western Iberia coastal morphology

et al. 2016

During summer (June, July, and August), northerly winds driven by the Azores anticyclone are prevalent over western Iberia. The Quick Scatterometer Satellite 2000 to 2009 summertime estimates reveal a broad high wind speed (≥7 ms−1) area extending about 300 km from shore and along the entire Iberian west coast. Nested in this large high‐speed region, preferred maximum regions anchored in the Iberian major capes, Finisterre, Roca, and S. Vicente, are found. Composite analyses of wind maxima were performed to diagnose the typical summertime synoptic‐scale pressure distribution associated with these smaller size high‐speed regions. The flow low‐level structure was further studied with a mesoscale numerical prediction model for three northerly events characterized by typical summertime synoptic conditions. A low‐level coastal jet, setting the background conditions to the marine atmospheric boundary layer (MABL) response to topography, was found in the three cases. The causes for wind maximum downwind capes were investigated, focusing on the hypothesis that western Iberia MABL responds to hydraulic forcing. For the three events supercritical and transcritical flow conditions were identified and expansion fan signatures were found downwind each cape. Aircraft measurements, performed during one of the events, gave additional evidence of the expansion fan leeward Cape Roca. The importance of other forcing mechanisms was also assessed by considering the hypothesis of downslope wind acceleration and found to be in direct conflict with soundings and surface observations.
