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. Contribuição do aninhamento do modelo Eta no modelo de circulação geral atmosférico e acoplado oceano-atmosfera do CPTEC na previsão do clima de verão sobre a América do Sul e Atlântico Tropical / Contribution of nesting regional eta model in atmospheric and coupled ocean-atmosphere general circulation model in seasonal forecast over South America and Tropical Atlantic
This work aims to verify the advantage of nesting Eta model in global coupled ocean-atmosphere model (CGCM) in climate forecast over South America and Tropical Atlantic. Three ensembles hindcasts of ten summer (December, January and February) between 1997 and 2006. The hindcasts consist of two global models from CPTEC, one atmospheric (AGCM;T062L28) and anot

3. Simulações de clima para o holoceno médio usando o MCGA do CPTEC, com ênfase sobre a América do Sul / Climate simulations of the mid-holocene as produced by the CPTEC atmospheric general circulation model in the south america
Este trabalho tem o objetivo de analisar o clima do Holoceno Médio (HM) para a América do Sul (AS), a partir da sinergia entre a forçante dos parâmetros orbitais e concentração de CO2, utilizando o modelo de circulação geral atmosférica (MCGA) do Centro de Previsão de Tempo e Estudos Climáticos (CPTEC) com resolução T062 e 28 níveis na vertical

5. Aspectos sinóticos associados à ocorrência do jato em baixos níveis na América do Sul - reanálise NCEP/NCAR e simulação com o MCGA CPTEC/COLA / Synoptics aspects associated to the occurrence of the low levels jet in the south America - reanalyses of the NCEP/NCAR and simulation with the MCGA CPTEC/COLA
Cases of LLJ occurrence to the east of Andes were identified in NCEP/NCAR reanalyses data and in daily results of a climate simulation with the CPTEC/COLA AGCM, to identify the associated atmospheric patterns. weather forecasting of a case when there was occurrence of LLJ was also evaluated. Analysis performed in different seasons indicated similar synoptic

6. Principais sistemas sinópticos que atuaram sobre a Península Antártica no verão de 2001/2002 e a circulação troposférica associada / The main synoptic system that effected the Antartic Peninsula in the 2001/2002 summer and the associated tropospheric circulation
The behaviour of synoptics systems which affected the Antarctica Peninsula and Drake Passage during the Operantar XX, in the 2001/2002 summer, were analysed in this study. Three main methods were developed. The first one, is to evaluate the behaviour of the large and mesocyclones which occurred in the area, during december, january and february, using satell

8. Balanço hídrico da região Sul/Sudeste da América do Sul simulado pelo modelo atmosférico CPTEC/COLA. / Hydrologic budget over southern/southeastern South America simulated by the CPTEC/COLA atmospheric model.
The La Plata River basin is the second basin of South America after the Amazon basin and is the fifth in a world-wide level. It is located at an international area that occupies territories of Argentina, Uruguay, Brazil, Paraguay and Bolivia, areas of great economic activity. In the present work, the hydrologic budget was studied, analysing the atmospheric a
