Abstract(s)
A agitação marítima tem um grande impacto nas operações navais. O Centro Geospacial Meteorológico e Oceanográfico Marítimo (CGEOMETOC) tem por missão dar apoio ambiental necessário ao planeamento, comando e controlo das operações navais na Marinha. Neste âmbito, o CGEOMETOC corre diariamente modelos de agitação marítima, de escala global às escalas das operações, cujas soluções são utilizadas para construir os produtos de apoio GEOMETOC. Estas soluções são também guardadas em base de dados para análises futuras, permitindo a caracterização da agitação marítima nos espaços de interesse nacional. Neste trabalho foi efetuado um tratamento e validação desses dados, guardados desde 2012, de forma a calcular uma climatologia da agitação marítima para os espaços marítimos de responsabilidade nacional. A validação foi feita através da comparação das soluções numéricas com as observações contemporâneas, registadas pelo Instituto Hidrográfico na sua rede MONIZEE, e revelou que as soluções do modelo traduzem com bastante exatidão as características da agitação marítima ocorrida em Portugal nos últimos 8 anos. A climatologia foi construída a partir da caracterização mensal dos parâmetros da altura significativa, período e direção da agitação marítima ao longo de 8 anos numa área compreendida entre os paralelos dos 30°N e 45°N e os merídianos dos 5°W e os 35°W. Este trabalho permitiu assim caracterizar a agitação marítima nas áreas de jurisdição nacional, assim como avaliar o desempenho do modelo usado operacionalmente nos locais onde estão colocadas 4 boias ondógrafo oceânicas (da rede MONIZEE), nomeadamente em, Leixões, Nazaré, Sines e Faro.
Gravitic Waves have a major impact on naval operations. The Centro Geospacial Meteorológico e Oceanográfico Marítimo (CGEOMETOC) has the mission of providing the necessary environmental support for the planning, command, and control of naval operations in the Navy. In this context, CGEOMETOC runs, in daily basis, sea wave models, from global scale down to the scales of operations, whose solutions are used to create GEOMETOC support products. These solutions are also stored in a database for future analysis, allowing for the characterization of maritime agitation in national areas of interest. In this work, a treatment and validation of these data, saved since 2012, were carried out to calculate a climatology of gravitic waves for national maritime areas of responsibility. Validation was made by comparing numerical solutions with contemporary observations recorded by Instituto Hidrográfico (IH) in its MONIZEE network, revealing that the model solutions accurately represent the characteristics of maritime agitation that occurred in Portugal over the past 8 years. The climatology was constructed based on monthly characterization of significant wave height, period, and direction of of gravitic waves over 8 years in an area between the parallels of 30°N and 45°N and the meridians of 5°W and 35°W. This work allowed for the characterization of maritime agitation in areas of national jurisdiction, as well as the assessment of the performance of the model used operationally at locations where 4 oceanographic wave buoys (from the MONIZEE network) are placed, namely in Leixões, Nazaré, Sines, and Faro.
