1. Impactos de El Niño y La Niña en las lluvias del Perú (1965-2007)
The impacts of El Niño (EN) and La Niña (LN) in rainfall in Peru are evaluated using monthly data (1965-2007) of 155 stations distributed over the three hydrographic drainages of Peru: 85 in the Pacific (VP), 21 in the Lake Titicaca (VT) and 49 in the Amazon (VA). To classify El Niño and La Niña is used the Index Troup Southern Oscillation (SOI) based on

2. Variabilidade oceânica associada à variabilidade climática da vazão na bacia do rio São Francisco / Oceanic variability related to river outflow at São Francisco Hydrographic basin
This research concerned to propose a valuation about the relationship between annual oceanic behavior and river outflow at São Francisco Hydrographic Basin, in Brazil, for the period from 1968 to 2004. Linear model based on multiple regression were built for annual river outflow at Ponte da Taquara, located at High São Francisco sub-basin. Climatic indexes

3. Objective method identification upper-tropospheric cyclonic vortices in the South Tropical region: validation and climatology / Método objetivo de identificação dos vórtices ciclônicos de altos níveis na região tropical sul: validação e climatologia
An Objective Method (OM) to identify Upper-Tropospheric Cyclonic Vortex (UTCV) in South Tropical region was developed based on relative vorticity and on horizontal flow of the wind round the centre of the system. As this synoptic system shows an irregular movement the weather forecasts become complex. The interannual and intrasazonal variability study of the

4. Fronts and frontogenesis during summer: geometrical and dynamical aspects and the influence over rainfall on the South American subtropics / Frentes e frontogênese no verão: aspectos geométricos, dinâmicos e impactos sobre as chuvas nos subtrópicos da América do Sul
Three different aspects related to summer precipitation over subtropical South America (SA) and the continental pattern of humidity transport in that season are studied. Firstly, a climatological point of view is adopted and it is shown that most of the humidity that enters SA through its northern coast, up to Par´a, comes from the tropical Northern Atlanti

5. Time variability of sea surface parameters in the tropical Atlantic using satellite and in situ data
The influence of the tropical Atlantic Ocean over the climate of Europe, Africa and America is well known today. However, several questions about high-frequency processes in this region remain open. This thesis addresses the characterisation of the diurnal and other short timescale variability of the meteo-ocean variables measured in the tropical Atlantic Oc

6. Biologia reprodutiva do peixe-rei, Elagatis bipinnulata (Quoy &Gaimard, 1825), capturado na zona econÃmica exclusiva (ZEE) do nordeste do Brasil
The rainbow runner (Elagatis bipinnulata), belonging to the family Carangidae, is one of the most important families of tropical marine fish, with a high commercial and sport-fishing value. It has a circumtropical distribution, being found, in the Atlantic Ocean, from the north of Massachusetts-USA, to the southern limit of the northeast coast of Brazil. The

7. EspÃcies de cirolanÃdeos (Isopoda, Crustacea) coletadas na plataforma continental e bancos oceÃnicos do Norte e Nordeste do Brasil
The cirolanids are isopods of the suborder Flabellifera that are found widely distributed in tropical regions of the world. The familyâs study is in embrionary stage, owning lacunae in groupâs taxonomy, ecology and biogeography. With good resource of familyâs exemplars collected recently in REVIZEE project, N-NE commissions, and material of oceanographica

8. Estudo numérico da circulação e da estrutura termohalina no Canal de São Sebastião. / Numerical study of the circulationand of the termohaline Structureat the São Sebastião Channel.
The Princeton Ocean Model was adapted to São Sebastião Channel (SSC) so as to study the seasonal changes of its circulation and thermohaline structure. Three numerical grids were nested. The coarse grid on Southeast Continental Shelf (SCS) and the fine grid on São Sebastião Channel with an intermediary grid on the region adjacent to the channel. The nume

9. The influence of the Pacific and Atlantic ssts in the South America monsoon rainfall / A influência das TSMS dos ocenos Pacíficos e Atlântico nas chuvas de monção da América do Sul
Monthly information of outgoing long wave radiation (OLR), sea surface temperature (SST), and rainfall from 22 meteorological stations in eastern South America were used to identify the rainfall characteristics of the South American Monsoon systems (SAMS). The 1961-1999 rainfall climatology for the area allowed the identification of two seasons with marked p

10. Metodos de analise de series temporais geofisicas: aplicacoes no estudo das variacoes interanual e interdecadal do nivel medio do mar no Atlantico Norte Extra-tropical / On Methods of geophysical time series analysis: applications in the study of interannual and interdecadal mean sea level in the Extra-tropical North Atlantic Ocean
Realizou-se um estudo do nivel medio do mar mensal, com a remocao de tendencias lineares e com filtragem, utilizando os dados obtidos em 22 portos oceanicos, no periodo de 1957-1986, no Oceano Atlantico Norte Extra-tropical (ANET). A metodologia adotada foi a de analise de Funcoes Ortogonais Empiricas (EOFs) e a de analise espectral (metodo de maxima entropi

12. Efeitos Inter-Hemisfericos de intensas fontes tropicais de calor / Inter-Hemispheric effects of strong tropical heat sources
The response over South America of the latent heat release in a strong perturbation (hurricane) moving over North Tropical Atlantic Ocean is investigated using a nonlinear semi-Lagrangian two layer primitive equation model. The model results show that such a perturbation propitiates a coupling with frontal system in the Southern Hemisphere and the convective
