Amorim, F. N.Cirano, M.Almeida, M. MartaMiddleton, John F.Campos, Edmo José DiasAmorim, F. N.Cirano, M.Almeida, M. MartaMiddleton, John F.Campos, Edmo José Dias2014-09-03T17:30:47Z20130278-4343http://repositorio.ufba.br/ri/handle/ri/15795v. 65Texto completo: acesso restrito. p. 121–140The Regional Ocean Modelling System (ROMS) with embedded nesting capabilities based on AGRIF, configured with a refined grid (1/36°) and realistic forcings (6-hourly winds and surface fluxes, daily large scale oceanic forcings and tides), was implemented to describe the seasonal circulation within the Eastern Brazilian Shelf (EBS) between 10°S and 16°S and its interaction with the mesoscale dynamics associated with the Western Boundary Currents (WBC) which flow over the slope: the Brazil Current/North Brazil Current-Undercurrent (BC/NBC–NBUC), as well as the contribution of the forcing mechanisms on the generation of the shelf/slope currents. The model results show, based on the methodology adopted, that for the northern limit (10°S) the northward flow is the dominant pattern while the southward flow appears as a shallow flow confined to the top 50 m of the water column during the spring/summer seasons. The surface circulation at the inner- and mid-shelves in this region is mostly influenced by the wind forcing, while at the shelf-break the currents are mainly driven by the slope currents during all seasons. In the middle (14°S) and southern (16°S) domains, there is an alternate dominance of the southward/northward flows for the first 150 m of the water column, with the dominance of the southward (northward) flow between October–February (March–September) at 14°S. However, the annual net transport in these regions is oriented southwards. On the other hand, in the sub-surface (View the MathML source∼150–400m) the dominance of the northward flow is clear. At 14°S, the inner-shelf circulation is mainly driven by the wind forcing and the mid-shelf circulation is forced by both the wind and the flow over the slope, while the currents at the shelf-break are more influenced by the currents at the slope. Finally, the inner- and mid-shelf currents at 16°S are mainly driven by the wind forcing, while the shelf-break currents present a poor correlation with the wind and a strong influence of the WBC dynamics.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-05-13T11:50:40Z No. of bitstreams: 1 1-s2.0-S0278434313002094-main.pdf: 9561218 bytes, checksum: 131e4d36f231c017242646c10ded7073 (MD5)Approved for entry into archive by Alda Lima da Silva (sivalda@ufba.br) on 2014-09-03T17:30:47Z (GMT) No. of bitstreams: 1 1-s2.0-S0278434313002094-main.pdf: 9561218 bytes, checksum: 131e4d36f231c017242646c10ded7073 (MD5)Made available in DSpace on 2014-09-03T17:30:47Z (GMT).
