Creator:: Matano, Ricardo P.
Abstract:: Analytical and numerical models are used to study the effects of a meridional ridge on the propagation of barotropic Rossby waves produced by distant wind stress forcing. The analytical model illustrates the qualitative aspects of the problem by solving a simplified form of the potential vorticity equation. The analytical results...

Creator:: Mesias, Jorge M., Matano, Ricardo P., and Strub, P. Ted
Abstract:: We present a modeling study of the upwelling ocean circulation off central Chile (34°–40°S). Using a primitive equation model, we make a numerical simulation of the ocean circulation for summer of 1993, a year characterized by moderate but persistent equatorward winds. The results indicate the formation of an eastern boundary...

Creator:: Schouten, Mathijs W. and Matano, Ricardo P.
Abstract:: The formation mechanisms and pathways of intermediate water in the Southern Ocean are analyzed from output of a high-resolution ocean general circulation model. Deep winter mixed layer formation in the Southern Ocean is diagnosed from the model results and is found to be mostly consistent with observations. Diapycnal water mass...

Creator:: Fetter, A., Lutjeharms, J. R. E., and Matano, Ricardo P.
Abstract:: The Agulhas Current is the western boundary current of the South Indian Ocean and is thought to play an important role in the global overturning circulation. In this study, we investigate the contribution from the wind stress field over each ocean basin of the southern hemisphere to the variability of...

Creator:: Miller, Robert N., Matano, Ricardo P., and Palma, Elbio D.
Abstract:: Alongshore flow in the direction of propagation of coastal trapped waves can result in upwelling at the shelfbreak. The intensity of this upwelling can be comparable in magnitude to wind-driven coastal upwelling, with its associated ecological features. Recent numerical experiments by Matano & Palma indicate that this upwelling results from...

Creator:: Matano, Ricardo P.
Abstract:: The oceanic circulation near the eastern margin of the African continent is dominated by the poleward flow of the Agulhas Current. The Agulhas Current separates from the African coast near the southern tip of the continent, makes an abrupt turn to the east (known as the Agulhas Retroflection), and flows...

Creator:: Strub, P. Ted, James, Corinne, Combes, Vincent, Matano, Ricardo P., Piola, Alberto R., Palma, Elbio D., Saraceno, Martin, Guerrero, Raul A., Fenco, Harold, and Ruiz-Etcheverry, Laura A.
Abstract:: Altimeter sea surface height (SSH) fields are analyzed to define and discuss the seasonal circulation over the wide continental shelf in the SW Atlantic Ocean (27°–43°S) during 2001–2012. Seasonal variability is low south of the Rio de la Plata (RdlP), where winds and currents remain equatorward for most of the...

Creator:: Combes, Vincent and Matano, Ricardo P.
Abstract:: Observations show abrupt changes in the oceanic circulation of the southwestern Atlantic. These studies report a southward drift of the Brazil/Malvinas Confluence (BMC) and a change in the spectral characteristics of the Malvinas Current (MC) transport. We address the cause of these changes using the result of a high-resolution numerical...

Creator:: Guerrero, Raul A., Piola, Alberto R., Fenco, Harold, Matano, Ricardo P., Combes, Vincent, Chao, Yi, James, Corinne, Palma, Elbio D., Saraceno, Martin, and Strub, P. Ted
Abstract:: Satellite‐derived sea surface salinity (SSS) data from Aquarius and SMOS are used to study the shelf‐open ocean exchanges in the western South Atlantic near 35°S. Away from the tropics, these exchanges cause the largest SSS variability throughout the South Atlantic. The data reveal a well‐defined seasonal pattern of SSS during...

Creator:: Combes, Vincent and Matano, Ricardo P.
Abstract:: This article presents the results of a high-resolution (1/12°), two-way nested simulation of the oceanic circulation in the southwestern Atlantic region. A comparison between the model results and extant observations indicates that the nested model has skill in reproducing the best-known aspects of the regional circulation, e.g., the volume transport...
