1. 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

2. 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

3. Interações trópicos-extratrópicos na escala de tempo intrassazonal durante o verão astral e seus efeitos na América do Sul / Tropical extratropical intraseasonal interactions during austraul summer and effects in south
In this study the interaction among the tropical convection in Indonesian region, the extratropical flow and the tropical convection in the South Atlantic Convergence Zone (SACZ) was analysed regarding the intraseasonal variability. The analyses were performed applying statistical techniques to the daily NCEP/NCAR reanalysis data set and to daily OLR obtaine
