The WOCE Community Modeling Effort (CME) general circulation model of the North Atlantic was used to investigate the behavior, nature, and dynamics of 50-day oscillations seen in the meridional component of velocity between 5° and 11°N, 35° and 55°W. Oscillations of the meridional component of velocity, with a period of about 50 days, appear as the seasonal meander pattern of the North Equatorial Countercurrent starts to break down in December. They appear first near 35° and are advected westward. They have a westward phase velocity of about O.1 m s−1, wavelength of about 6000 km, and a very slow eastward group velocity. Their period, phase speed and wavelength agree with recent observations. Calculation of the leading terms from the full vorticity equation following a model decomposition in the propagation region showed that the oscillations were first and second mode baroclinic Rossby waves. Repetition of the vorticity analysis on an undecomposed snapshot during the period of retroflection reve...
