1. The north Brazil undercurrent and the wind driven hydrodynamics in Japaratuba submarine canyon, Brazil
Abstract The circulation induced by the wind and the North Brazil Undercurrent (NBU) in and surrounding the Japaratuba submarine canyon on the continental shelf of the basin of Sergipe and Alagoas is described using numerical modeling. The numerical simulations were implemented to determine the canyon influence in the local hydrodynamics and in the volume fl

2. Análise do Desempenho do Modelo WRF num Episódio de Vento Intenso e Persistente num Grande Reservatório Tropical
Resumo O presente estudo apresenta uma aplicação do modelo de mesoescala WRF à simulação de um episódio de vento intenso e persistente que ocorre com frequência irregular no reservatório de Guapé, MG. Tal evento altera a rotina da população na região, fazendo com que, por exemplo, a embarcação que faz a travessia entre as cidades de Guapé e Ca

3. Circulation on the Inner and Mild Continental Shelf of the State of São Paulo during summer: numeric studies / Circulação na Plataforma Continental Interna e Média do Estado de São Paulo durante o verão: estudos numéricos
The aim of this study was simulate the hydrodynamic of the Inner Continental Shelf of the State of São Paulo (PCISP) and of the Mid Continental Shelf of the State of São Paulo (PCMSP) during summer, in response to the density gradient forcing, to the climatological wind shear stress forcing and to the tide forcing, applying the tridimensional hydrodynamic

4. Verificação da linearidade da resposta oceânica à forçante do vento em larga escala / Verification of the linear ocean response to large scale wind forcing
A resposta oceânica a perturbações com períodos e comprimentos significativamente maiores que o período inercial e que o raio de deformação de Rossby se dá na forma de ondas de Rossby planetárias. Geralmente, as perturbações são atribuídas a variações no rotacional do vento via bombeamento de Ekman. A passagem dessas ondas causa deformação d

5. A finite element model for the ocean circulation driven by wind and atmospheric heat flux
A finite element model for solving ocean circulation forced by winds and atmospheric heat fluxes is presented. It is vertically integrated 1 1/2 layer model which solves the motion and continuity hydrodynamic equations coupled with the advection-diffusion transport equation for temperature. A space-time Petrov-Galerkin formulation is used to minimize the und

6. Variabilidade subinercial das correntes na plataforma continental ao largo de Cabo Frio (RJ): observações / Subtidal variability of the currents on the continental shelf off Cabo Frio (RJ): observations
This work was developed within the context of the continental shelf hydrodynamics, with the aim of studying the subtidal variability of the currents in the far north of the South Brazil Bight (SBB). The area of the study is located in the vicinity of Cabo Frio (RJ) and Arraial do Cabo (RJ) (approximately 23º S / 42º W). Despite being a well known and studi

7. NUMERICAL MODELING OF SEWAGE PLUME DISPERSION FOR THE SANTOS OUTFALL / Modelagem numérica da dispersão da pluma do emissário submarino de Santos
Sewage plume dispersion for the Santos outfall was studied using numerical models, coupling hydrodynamic, near field and far field models. Experiments were conducted for the 1979 original outfall design, for the new 2009 outfall configuration and also for a third arrangement suggested here, which duplicates the emissary length comparatively to the original 1

8. Numerical model of oil spill as an environmental management method in contingency plan, applied to São Sebastião channel (SP). / Modelagem numérica do comportamento de derrames de óleo como método de gestão ambiental, em planos de contingência, aplicada ao canal de São Sebastião (SP).
The application of numeric models for analysis of oil spill in the coastal environments becomes one of the most important ways to understand the behavior of the oil in this case of impact, giving subsides to the prediction of the displacement of the patches and allowing best efficiency in the control of the extension of the impact agent. These assumptions gi

9. The role of the local and remote effects on the upwelling system variabilities along the western coast of South America, during El Niño / O papel de efeitos locais e remotos em variabilidades do sistema de ressurgência ao largo da costa oeste da América do Sul durante o El Niño
Off the western coast of South America, the coastal upwelling system presents an exceptional productivity, a result of the high efficiency of the biological ecosystem in converting the primary production into biomass. These chemical and biological processes are strongly modulated by the physical environment. For instance, during El Ni~no events the fishery p

10. Inter-relação paleossolos e sedimentos em lençois de areia eolica da Formação Marilia (noroeste da Bacia Bauru) / Iterrelation of palaeosols and sediment in the ancient Marilia Formation aeolian sand sheets (northwestern Bauru Basin)
The Marília Formation (Maastrichtian), outcropping in the northwestern portion of the Bauru Basin (Goiás and Mato Grosso do Sul brazilian states), is interpreted here as an ancient Aeolian sand sheet. The vertical succession, c.150 m thick, is made up of very fine to medium-grained sandstone and, it is characterised by cyclic interbedding of sediments and

11. Padrões de circulação anômala associados a episódios úmidos e secos no sul do Brasil / Anomalous circulation patterns associated with wet and dry events in southern Brazil
The characteristics of the atmospheric circulation associated with persistent wet and dry events in Southern Brazil during all seasons were studied from 1979 to 2002, using precipitation pentad data. The result shows that the dominant oscillations of rainfall variability have periods between 2 and 6 pentads. Superposition of different periods was also identi

12. Investigation of gravity wave momentum fluxes in the upper atmosphere derived from airlow / Investigação do fluxo de momento das ondas de gravidade na alta atmosfera através da aeroluminescência
In this study, momentum fluxes due to gravity wave propagation into the MLT region was calculated by using airglow image data and theoretical modeling. Airglow O(1S) 557,7, O2(0-1,b) and OH NIR images were obtained from Cachoeira Paulista (22,7°S; 45,0°W) and São João do Cariri (7,4°S; 36,6°W) and processed for estimation of gravity wave intrinsic para
