Texte intégralThe planktonic foraminiferal assemblages of two piston cores from western tropical Atlantic covering the last 30,000 years have been analysed together with paleoceanographic ANN sea surface temperature reconstruction and ?18O and ?13C of the shallow dwelling planntonic foraminifera Globigerinoides ruber \'white\'. These proxies reveal that during the Last Glacial Maximum and during the Heinrich 1 and Younger Dryas cold events, the western tropical experienced warm periods. This study suggest that during these warm intervals a pronounced accumulation of heat and salt occurred at western tropical Atlantic, as a result of cross-equatorial heat and salt transport decrease. At the end of these events, the intensification of cross-equatorial heat and salt transport cooled and freshened the western tropical surface waters. This study suggests the western tropical Atlantic served as a heat and salt reservoir during deglaciation.

Texte intégralThe objective of this study is to investigate the variability of the surface heat budget components in the tropical South Atlantic, between 5oS and 30oS and for the period between 2000 and 2005, through a methodology based on a multi--satellite approach. We aim to verify if the heat exchange processes in the ocean are dominated by large scale and interannual variability. The sea surface temperature, integrated water vapor and precipitation data are obtained by the Tropical Rainfall Measuring Mission (TRMM) microwave satellite. Wind vectors are measured by the QuikSCAT scatterometer satellite and the estimates of the shortwave and longwave radiation are distributed by the Surface Radiation Budget projetct. We used the algorithm developed by Liu79 et. al. (1979) to estimate the latent and sensible heat fluxes. To obtain a more precise estimation of the turbulent fluxes, we used an algorithm developed by Fairall et. al. (1996), where the Webb correction for the latent heat flux and the sensible heat flux due to the rainfall were included in the calculations. The results were analized in terms of the mean, anomaly, and space--time (Hovmöller) diagrams. The estimates of the surface heat balance showed that the South Atlantic loses heat to the atmosphere, mostly in the form of latent heat fluxes, south of 7oS. On average, there is a maximum in heat loss of -100W/m2 between 12oS e 17oS. The net surface heat flux has a strong seasonal cycle, with an amplitude of about 250W/m2. The surface energy balance shows significant correlations with remote phenomena at interannual scales indicating the establishment of rapid teleconnections through the atmosphere.

Texte intégralThe formulation and improvement of Brazilian foreign politics requires the development of a world regionalization from a perspective of national Brazilian interests. Thus, we attempt to determine the correlation between the Brazilian geopolitical thinking inherited from the military period and the volume / nature of the economic flows between Brazil and Africa, especially regarding the behavior of Brazilian foreign trade with African countries. In practice, there is the emergence of trade relations with countries located in an arc outside the more traditional Atlantic, although it still appears in broad focus. This new regionalization of trade Brazil ? Africa, especially for goods of higher technological content, you still need to show some survival guide for new long-term diplomatic actions.
A formula??o e aperfei?oamento da pol?tica externa brasileira exige a elabora??o de uma regionaliza??o mundial a partir de uma perspectiva dos interesses nacionais brasileiros. Desta forma, busca-se determinar a correspond?ncia entre o pensamento geopol?tico brasileiro herdado do per?odo militar e o volume/natureza dos fluxos econ?micos entre Brasil e ?frica, especialmente no que se refere ao comportamento do com?rcio exterior brasileiro com os pa?ses africanos. Na pr?tica, nota-se a emerg?ncia de rela??es comerciais com pa?ses localizados em um arco mais externo ao tradicional arco atl?ntico, embora este ?ltimo ainda apare?a em amplo destaque. Essa nova regionaliza??o dos fluxos comerciais Brasil ? ?frica, com destaque para mercadorias de maior conte?do tecnol?gico, ainda precisa comprovar certa perenidade para balizar novas a??es diplom?ticas de longo prazo.

Texte intégralA study was performed with physical data at the surface produced by the implementation of the numerical model POM and chlorophyll a data from the MODIS sensor, in the Tropical and South Atlantic, with the aim of to analyze the spatial variations of their correlations. The hydrodynamic model was subjected to a validation with data of Project PIRATE and MODIS sensor, obtaining satisfactory results, especially at the surface. The chlorophyll a values have high correlation with physical variables at the surface, but these values are influenced by the presence of annual and semiannual signals in the time series. Then, the analyses were carried out after removal of these signals from the series. The cross-correlations between physical variables and chlorophyll a had high magnitudes showing, in general, characteristic spatial pattern of negative correlations within the Subtropical Gyre and positive in other regions, for surface temperature and salinity and sea surface level. This spatial pattern is most evident in surface elevation and temperature, presenting lag in the biological response time nearly zero within the Subtropical Gyre and Equator, with a predominance of delays of the responses in other regions. The cross-covariance is calculated for several points along the meridian of 20º W for surface elevation and surface temperature, verifying agreement with the results obtained by the cross correlation. Spectral analysis of this covariance shows the occurrence of some signals, including signals with periods of 3.5 and 0.7 years (which are probably associated with ENSO phenomena) and the period of 0.33 years (that can be related to resonances of the annual signal). The signature of these signals showed latitudinal variability.

Texte intégralA distribuição e intensidade dos ciclones afeta diretamente as atividades humanas devido a precipitação e fortes ventos associados a esses sistemas. O objetivo principal deste trabalho é entender as mudanças nos ciclones gerados no Atlântico Sul devido às mudanças climáticas, focando em seus mecanismos geradores e intensificadores. Os ciclones foram identificados e rastreados utilizando a vorticidade relativa em 850hPa, calculada a partir do campo de ventos horizontal. Também foram usadas composições centradas para a análise da estrutura e evolução dos ciclones durante seu desenvolvimento. A climatologia de ciclones feita com o NCEP-CFSR mostra quatro regiões ciclogenéticas principais no Oceano Atlântico Sul: na costa sul do Brasil (SE-BR, 30°S), sobre o continente próximo da desembocadura do Rio da Prata (LA PLATA, 35°S), na costa sudeste da Argentina (ARG, 40°S-55°S) e no Sudeste do Atlântico (SE-SAO, centrada em 55°S, 10°W). Para analisar as mudanças no desenvolvimento dos ciclones, nós utilizamos os experimentos histórico (1980-2005) e RCP8.5 (2074-2099) do HadGEM2-ES (CMIP5). O HadGEM2-ES é capaz de reapresentar as principais características dos ciclones do Atlântico Sul, quando comparado à climatologia. No entanto, existe uma subestimativa do número de ciclones no lado equatorial da região de máxima atividade ciclônica, principalmente na região LA PLATA. A projeção futura HadGEM2-ES no cenário RCP8.5 mostra uma redução de aproximadamente 10% na ciclogêneses no domínio do Atlântico Sul, principalmente associada ao deslocamento em direção ao polo da região de máxima atividade ciclônica. Porém, a região LA PLATA apresenta um pequeno aumento em sua atividade ciclogenética (6.1 e 3.6%), no verão e inverno, respectivamente). O aumento na ciclogênese em 30°S está associada ao fortalecimento do jato de altos níveis e ao aumento da advecção quente e de umidade nessa localidade. O aumento do transporte de umidade dos trópicos está associado também à intensificação dos ciclones observada na projeção futura, principalmente ao norte de 35°S. Por fim, uma regionalização com o modelo WRF foi usada para melhorar a resolução do modelo climático. Porém, as simulações regionais subestimaram os ciclones em número e intensidade. A única região que em as regionalizações apresentaram melhor desempenho foi a LA PLATA, devido a uma melhor representação de feições locais associadas a orografia e processos úmidos. A regionalização do cenário futuro RCP8.5 também apresentou aumento da ciclogênese do LA PLATA, mas para o inverno. Tanto a projeção RCP8.5 do HadGEM2-ES quanto sua regionalização mostram que a ciclogênese em algumas regiões da América do Sul está aumentando, principalmente devido ao aumento de umidade em baixos níveis da atmosfera e fortalecimento do lado ramo equatorial do jato de altos níveis. Os ciclones nessas localidades serão intensos (entre 20°S e 30°S) e tendem a afetar uma região mais próxima à costa.

Hsu and Chen (2011) suggested that the decadal rainfall variability along the Western Pacific coast during July-October was found associated with the SST variability in the Western South Pacific, which is called the SPDO. The SPDO index is highly correlated with SST not only in Western South Pacific but also in other ocean basins such as the tropical Atlantic. Tropical Atlantic was about one year ahead of Western South Pacific in 1975-1994. Does “tropical Atlantic leading Western South Pacific” imply that tropical Atlantic will impact Western South Pacific through a process similar to Atmosphere Bridge? This study applied the regression analysis and verified with couple model, to understand the relationship between tropical Atlantic and Western South Pacific, and the reason can lead to the SST decadal variability in Western South Pacific. Combine the results of observation data analysis and model simulation. The low-level convergence anomaly occurred over the positive SSTA in tropic Atlantic and divergence anomaly occurred at about 120oW in Southern Hemisphere through an east-west vertically overturning circulation, and then the air-sea interaction caused anticyclone in the Western South Pacific. Concluding remarks from observation data analysis: The anticyclone in the Western South Pacific caused the Western South Pacific warm through the joint process of latent heat flux and ocean Ekman pumping. Therefore, the Western South Pacific was connected to the tropical Atlantic by atmospheric-ocean coupling process in these two regions.
