Surface currents and significant wave height variability: a numerical investigation of the Agulhas current region
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Marechal, Gwendal; Ardhuin, Fabrice.
Advances in the understanding and modelling of surface currents have revealed the importance of internal waves, mesoscale and submesoscale turbulence. Indeed all these features should have a large influence on wind waves, and in particular wave heights are expected to be modified by refraction. Still, the quantitative impact of currents on waves is not well known due to the complexity of the random wave fields and currents that are found in the ocean, and the lack of observations of both currents and waves at scales shorter than 150 km. Here we use novel satellite altimetry data and state of the art phase-averaged numerical wave models forced by currents at different resolutions in the Agulhas region. We find that a numerical wave model that uses surface...

The Sea State CCI dataset v1 : towards a Sea State Climate Data Record based on satellite observations

Sea state data are of major importance for climate studies, marine engineering, safety at sea, and coastal management. However, long-term sea state datasets are sparse and not always consistent, and sea state data users still mostly rely on numerical wave models for research and engineering applications. Facing the urgent need for a sea state Climate Data Record, the Global Climate Observing System has listed Sea State as an Essential Climate Variable (ECV), fostering the launch in 2018 of the Sea State Climate Change Initiative (CCI). The CCI is a program of the European Space Agency, whose objective is to realize the full potential of global Earth Observation archives established by ESA and its member states in order to contribute to the ECV database....
