Gulf Stream warm core rings are intense, isolated eddies which form to the north of the Gulf Stream from cutoff meanders which detach from the Stream. After their formation they are embedded in the cooler Slope Water which flows generally westward, impinging on the continental slope near 70 W. Observations indicate that the Slope Water flows westward at approximately 5 cm/s. In this study, the effect of background shear flows on anticyclonic eddy motion is examined using a two layer primitive equation model. The effect of various lateral shear profiles is considered for barotropic and equivalent barotropic eddies. Results indicate that eddy zonal propagation is dependent on the eddy initial vertical profile and form of the background shear lateral profile. Eddy meridional speeds are found to be insensitive to background shear profile or strength
