Última Modélisation haute-résolution des courants dans le Golfe de Guinée : Etude des oscillations bimensuelles. ArchiMer Guiavarch, Catherine. Currentmeter measurements on the continental slope of the Gulf of Guinea (near 7°40 S) point out a biweekly oscillation of the currents, bottom intensified and oriented along the bathymetry. Those energetic oscillations dominate the signal. A three-dimensional high-resolution primitive equation model (NEMO/OPA) of the Gulf of Guinea has been developed to study the oscillations and their forcing mechanism. The data does not support the tide as a forcing mechanism and the wind-forced regional model reproduces biweekly oscillations, which fit the data quite well. Experiments with different forcings have been run to explore the origin of the biweekly variability. Those experiments highlight the equatorial origin of the oscillations forced by equatorial...
