Bettencourt, J.H. and Guedes Soares, C. (2021), “Surface circulation in the Eastern Central North Atlantic”, Developments in Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A., (Eds.), Taylor and Francis, London, UK, Vol 2, pp. 785-790.
The surface circulation in the Eastern Central North Atlantic is studied using a high resolution primitive equation regional ocean model simulation. The model is forced by climatological surface momentum, heat and freshwater fluxes and open ocean boundary conditions. Comparisons with drifter-derived velocity estimates show that the model is able to reproduce the main features of the surface circulation in the coastal Portuguese waters and in the Portuguese archipelagos of Azores and Madeira. The Azores Current (AzC) appears as a meandering zonal jet centered around 34º N, flowing eastward. The western Iberian margin is characterized by an seasonal upwelling regime where a cooling of near shore waters occurs between late spring and early autumn. Mesoscale activity is present in the upwelling front as coastal filaments and mesoscale eddies. The northward Portugal Coastal Counter Current is a prominent feature of the coastal circulation.
