1. Effects of atmospheric oscillations on infectious diseases: the case of Chagas disease in Chile
BACKGROUND Currently, there is an increasing global interest for the study of how infectious diseases could be linked to climate and weather variability. The Chagas disease was described in 1909 by Carlos Chagas, and is caused by the flagellate protozoan Trypanosoma cruzi. The Chagas disease is considered one of the biggest concerns in public health in Lat

2. 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

3. Climatologia de bloqueios atmosféricos no hemisfério Sul: observações, simulações do clima do século XX e cenários futuros de mudanças climáticas / A Climatology of Southern Hemisphere Blockings: Observations, Simulations of the 20th Century and Future Climate Change Scenarios.
Este estudo discute uma climatologia de 59 anos (1949-2007) de bloqueios no Hemisfério Sul (SH) usando dados de altura geopotencial em 500-hPa das reanálises do National Center for Environmental Prediction / National Center for Atmospheric Research (NCEP-NCAR). A variabilidade espaço-temporal dos eventos de bloqueio e associações com o El Niño/Oscilaç

4. Potenciais influências de anomalias positivas e negativas na camada de gelo marinho no mar de Ross na circulação atmosférica do Hemisfério Sul / Potential influences on the southern hemisphere atmospheric circulation of negative and positive sea ice extension anomalies in the ross sea
This study have used the CPTEC/INPE AGCM to explore the role of sea ice extent in the Ross Sea as a forcing of the asymmetric atmospheric circulation in the southern hemisphere during the austral winter (July-September), on a seasonal scale. The impacts have been assessed from the standpoint of positive and negative observed anomalies in ice extent in the Ro

5. Storm-track na América do Sul e vizinhanças: climatologia, variabilidade e mudanças climáticas / Storm-tracks over South America and adjacent areas: climatology, variability and climate change
This study deals with an extratropical cyclone climatology for South America (SA), Antarctic Peninsula and adjacents oceans in the austral winter and summer seasons for the current and future climate. An automatic and objective method to monitoring specific features of meteorological fields of the "European Centre for Medium Range Weather Forecast"(ECMWF) an

6. 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
