Scatterometers provide important global information on the air-sea interface (fluxes) and on ocean forcing by their wind and surface stress products. Wind stress forces ocean dynamics, triggers mixing of water and evaporates water. Webwind-driven contribution can be isolated from the total observed current. [6] The second step of the study is to use these high-frequency wind-driven currents together with the ECMWF (European Centre for Medium-Range Weather Forecasts) wind stress data to fit a wind-driven current model based on Ekman theory [Ekman, 1905].
