Abstract
The oceanic features in the eastern and southeastern brazilian shelf/slope south
 of 13S is investigated using ROMS (Regional Ocean Model System). The model
 integration was 9 years and it was forced with: i) 6-hourly synoptic atmospheric
 data from NCEP; ii) initial and boundary conditions from OCCAM (Ocean Climate
 Circulation Advanced Modelling) monthly mean climatology and iii) tidal
 forcing from TPXO 7.1 global data set. The model results were compared with
 observations, which consisted in thermodynamic MDL (Mixed Layer Depth) climatology,
 satellite data, measurements from tide gauges along the shelf and currents
 measurements values from literature. The simulated currents represented well the
 BC (Brazil Current)-IWBC (IntermediateWestern Boundary Current) System. The
 BC - IWBC system at 22S cross-shelf section, where the mean alongshelf velocity
 represents our simulation capability of reproducing the western boundary currents,
 showed poleward BC and a opposing IWBC. At this section, the BC velocity core
 is in 50 m with 0.41 m.s−1 and the IWBC core around 800 m with 0.15 m.s−1.
