Abstract
The behavior of the isolated vortices over the topographic-βis considered with the quasi-geostrophic two-layer model, in the limit of very shallow upper layer, in the absence of planetary-β. The results are compared with the observed Kurshio warm-core rings. When a ring drifts southward (northward) relative to the meridional mean current, it radiates (does not radiate) Rossby waves in the lower layer. Even when the lower layer is radiating, the decaying is very slow as long as the ring drifts closely to a background current.
