【摘要】A 1.5-layer quasi-geostrophic reduced gravity ocean circulation model is used to study the propagation of mesoscale eddies across a western boundary current(WBC)either leaping across or penetrating in an anti-cyclonic path through the gap.The steady leaping WBC nearly blocks all eddies from propagating across it through the gap completely.However,both cyclonic and anti-cyclonic eddies can migrate across a penetrating WBC in the vicinity of a gap,while inducing an opposite type of eddies on the cyclonic side of the WBC by weakening or strengthening the intrusion of the WBC.Both type of eddies gained strength from the WBC in the course of the propagation across the WBC in the gap.Eddies approaching the gap from the upstream are found to migrate more easily into the western basin due to the advection of the WBC.The migration speeds of the eddies are almost unchanged by the presence of the WBC in all experiments. 【总页数】12页(P.2098-2109)
