1. Cephalopoda as prey of juvenile Southern elephant seals at Isla 25 de Mayo/King George, South Shetland Islands
The aim of the present study was to enhance the knowledge of the feeding habits of the juvenile component of the population of Southern elephant seals [Mirounga leonina (Linnaeus, 1758)] from Isla 25 de Mayo, South Shetland Islands, age class whose diet information is scarce. A total of 60 individuals were stomach lavaged in the spring - summer seasons of th

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. River level sensitivity to SOI and NAO in Pantanal and Amazonia.
Water level in rivers of central and northern South America (SA) is primarily driven by fluctuations in rainfall that is largely controlled by regional and global sea-air-land interactions. In this work it is evaluated the role of changes in equatorial Pacific and north Atlantic ocean-atmospheric interactions in regulating river level in Pantanal and Amazoni

4. Eventos extremos de precipitação no leste da Amazônia. / Extreme events of rainfall in Eastern Amazon.
The aim of this study was to characterize the extreme events of rainfall in Eastern Amazon, to analyze on ocean-atmosphere conditions in global scale associated with intense occurrence periods of these events, to contribute for temporal variation comprehension of rainfall extreme events, as well as of determinant phenomena to its occurrence and to make furth

5. Análise espectral do decréscimo da velocidade do vento acima do jato de nível baixo em situações de El Niño-oscilação sul (ENSO) sobre Porto Alegre, Brasil
A turbulência dentro da Camada Limite Planetária (CLP) apresenta as informações das escalas temporais e espaciais dos sistemas sinóticos. Esta memória está associada ao decréscimo do vento acima do núcleo do jato no perfil vertical do vento. O perfil vertical do vento apresenta a ocorrência de Jatos de Baixos Níveis (JNB), sendo que estes jatos es

6. Interdecadal variability of precipitation in the Western Brazilian Amazon / Variabilidade interdecadal da precipitação na Amazonia Ocidental brasileira.
The present work focused on the interdecadal variability of precipitation in the Western Brazilian Amazon in order to help improve this knowledge and, in addition, to analyze, study and evaluate the low-frequency variability of the hydrological cycle in this region. To this end, we used data collected from conventional rain gauge stations 5, available at the

7. 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

8. Relação sol-terra estudada através de anéis de crescimento de coníferas do holoceno recente e do triássico / Sun-earth relationship studied by tree growth rings in conifers from holocene and triassic
The study of the Sun and of its energy flux variations is recent and fully experimental. For this reason , if is very important develop studies in order to understand the past and predict the future using natural records at the Earth surface to monitor solar variations and their effects on climate. The studies about the Sun s variations and Sun-Earth-Climate

9. Previsão de atributos do clima e do rendimento de grãos de milho na região Centro-Sul do Brasil / Forecast of climatic features and corn grain yield in the Brazilian Center-South region
Crop forecast has become an important tool for the private and public agricultural policies to be established. Generally, crop forecast is composed by climatic forecast and the yield estimative of growth of economically interesting parts of crops. The climatic forecast can be performed through the analyses of historical series of the climatic features and of

11. Estagnação de massa de ar quente e seco sobre a região central do Brasil / Stagnation of warm and dry air masses in the central region of Brazil
In the Southeast Region, southern parts of Central-West and northern parts of South Regions, Stagnations of Warm and Dry Air Masses (EMAQS) occur between April and September months. They are characterized by positive temperature anomalies and negative precipitation anomalies, persisting for several days. This situation causes an increase in air pollution and

12. Estudo sinotico de periodos deficientes de chuvas no Rio Grande do Sul / Synoptic study on periods of deficiency over Rio Grande do Sul/Brazil
The rainfall regime in the State of Rio Grande do Sul (Brazil) is characterized by a homogeneous monthly distribution and a low interannual variability. A spacial series considering 39 years of precipitation data (1952-1990) was used to analyse the years which had periods of rain deficiency. In the years 1988 and 1989 the annual precipitation presented meani
