English abstract | Velocity-based parametric models are often used in the oceanographic literature either in theoretical studies that involves linear stability properties or as boundary-initial conditions for regional implementations of numerical models. However, most of these models were developed for the Gulf Stream (Niiler & Robinson, 1967; Luther & Bane, 1985; Robinson et al., 1988; Arango et al., 1992; Xue & Mellor, 1993; Gangopadhyay et al., 1997). Because the Brazil Current (BC)- Intermediate Western Boundary Current (IWBC) System is unique in terms of its vertical structure as it flows off SE Brazil, an original parametric model has been developed and is presented in this paper. The model parameterizes both the surface-core structure of the BC as well as the intermediate level-core of the IWBC, keeping their basic features such as the asymmetric configuration due to their interaction with the topography |

Estes, no entanto, foram desenvolvidos na sua maioria para a Corrente do Golfo (Niiler & Robinson, 1967; Luther & Bane, 1985; Robinson et al., 1988; Arango et al., 1992; Xue & Mellor, 1993; Gangopadhyay et al., 1997). O sistema formado pela Corrente do Brasil (CB) e pela Corrente de Contorno Intermediaria (CCI) apresenta caracterısticas dinamicas singulares enquanto flui ao largo do SE brasileiro, quando comparada as demais correntes de contorno oeste do oceano mundial |
