1. Modelos Acoplados do IPCC (CMIP3-CMIP5) e o Gradiente Meridional de Anomalias de Temperatura da Superfície do Mar (TSM) no Oceano Atlântico Tropical
Resumo Este estudo investigou a sensibilidade de modelos acoplados oceano-atmosfera do CMIP3 e do CMIP5 para o período de 1979-1999 em simular a magnitude do gradiente meridional de anomalias de Temperaturas da Superfície do Mar (TSM) no Atlântico Tropical. Nos resultados são apresentadas análises comparativas para este gradiente meridional de anomalias

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. Measures of the interannual marine variability on southeast Brazilian bight and its relationship to the spawning areas of Brazilian sardine (Sardinella braziliensis) / Medidas da variabilidade interanual marinha sobre a plataforma continental sudeste do Brasil e sua relação com áreas de desova da sardinha-verdadeira (sardinella brasiliensis)
This work aims to investigate the relation of marine interannual variability in a region located in southern coast of Brazil, also known as the Southeast Brazilian Bight (SBB) and the spawning areas of the Brazilian sardine (Sardinella braziliensis) in SBB. SBB marine ecosystems are related to a strong influence of a coastal upwelling system. Variables used

4. Space-temporal variability of chlorophyll-a concentration and sea surface temperature estimated from satellite in the Brazilian Southeast Continental Margin / Variabilidade espaço-temporal da concentração de clorofila-a e temperatura da superfície do mar estimadas por satélite na Margem Continental Sudeste Brasileira
The objective of this work was to analyze the space-temporal variability of the chlorophyll-a concentration (Chl) and the sea surface temperature (SST) in the Brazilian Southeast Continental Margin (BSCM), between jan/1998 and dec/2006. Images from SeaWiFS e AVHRR were used for the extraction of the Chl and SST data respectively. Besides, Southeast Oscillati

5. Influência do gelo marinho antártico no setor austral sudoeste do Atlântico Sul / The influence of antactic sea ice in the austral and southwest sector on the south atlantic
In this work the interaction between Antarctic sea-ice and the South Atlantic ocean (austral and southwestern sectors) is investigated. To accomplish this satellite-observed sea-ice concentration (SIC) and a coupled model from NCAR-CCSM3 (National Center for Atmospheric Research - Community Climate System Model version 3) were employed. Three 150-year simula

6. Relação entre a precipitação pluvial na região Nordeste do Rio Grande do Sul e a Temperatura da Superfície do Mar dos Oceanos Atlântico e Pacífico
Vários estudos fornecem evidências de que os oceanos Atlântico e Pacífico desempenham um papel significativo nas flutuações climáticas que ocorrem na região Sul do Brasil , influenciando principalmente na precipitação pluvial. Dentre as variáveis mais utilizadas, pesquisadas e que mais influenciam na precipitação pluvial, destaca-se a Temperatur

7. Atividade Convectiva no Sul da América do Sul / Mesoscale Convective Systems (MCS) at South of South America
In this work synoptic and mesoscale aspects are analyzed in association to the formation of Mesoscale Convective Systems (MCS) at South of South America (SA) that reached the State of Rio Grande do Sul (RS) in some moment during its life time. The selected period involves the month of February of the years 2002 to 2005. Among the identified MCS, two cases ha

8. Relações entre as anomalias de TSM do atlântico e pacífico e as precipitações na amazônia oriental / Relationships between the atlantic and pacific SST anomalies and the eastern amazon rainfall
The seasonal and interannual rainfall variability in the Eastern Amazon region was related to the Tropical, South Atlantic and Equatorial Pacific SSTA. 3 x 3 contingency tables, evaluated by the Relative Operating Characteristics Score were used to check the simultaneous and up to 12 months lagged occurrence of 3 rainfall categories (below, near and above no

10. 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

11. x / Experimentos numericos com modelos climaticos media zonal
Two statistical-dynamical models, a quasi-geostrophic and a primitive equations model are developed. These are used to conduct numerical experiments about the zonally-averaged atmosphere, with emphasis on the Southern Hemisphere climatic processes. The experiments consider the climatic effects caused by the sea-surface temperature (SST) anomalies and by land

12. Fontes de calor nos tropicos e escoamentos anomalos de larga escala associados com anomalias de precipitacao no nordeste do Brasil / Heat source at the tropics and anomalous runoff of large scale associated with anomaly of precipitation in the northeast Brazil
An analysis in the monthly departure of the relative vorticily field (æ ) over the globe and monthly departures of the sea surface temperature (SST) in the Tropical Atlantic Ocean is performed for years of droughts and floods over Northeast Brazil, in the period from 1963 to 1980. Planetary scale wavelike patterns were observed in the æ field, similar to t
