No abstracts are to be cited without prior reference to the author.A three‐dimensional eco‐hydrodynamical model of high resolution is applied to simulate the seasonal and interannual variability of ocean circulation and marine ecosystems in the CentralEastern basin of the North Atlantic (CENA) including the Canarian upwelling system. Simulated temperature and salinity fields agree well with satellite and expeditionary observations in the period 1998–2006. According to model results and observations, in winter, “spots” of maximal phytoplankton biomass are often located in upwelling zones in the open ocean on the periphery of cyclonic eddies rather than in the coastal upwelling zones. In summer, when phytoplankton biomass reaches maximal values, maxima of phytoplankton are located in the coastal upwelling zones. Simulated surface phytoplankton distributions are in qualitative agreement with surface distributions of chlorophyll a derived from satellite data. Interannual changes in mean annual temperatures ...
