Decadal variation in the annual rainfall pattern in the State of São Paulo.
Brazil is one of the largest producers of sugarcane and the Sao Paulo State is currently responsible for 60% of the national production. Areas previously used for livestock and citrus production have been gradually substituted by sugarcane due, mainly, to the current Brazilian government incentive f...

Surface wind modualtion by oceanic thermal gradients in the Brazil- Malvinas Confluence region.
The Brazil-Malvinas Confluence (BMC) region in the South Atlantic Ocean is characterized by the thermal gradients of the meeting between the warm Brazil Current (BC) and the cold Malvinas Current (MC). The region is considered a key region for understanding the linkage between Antarctica and South A...

Twenty years of research on forest clearing fires in Amazonia.
This paper presents a compilation of the main results obtained by this research group in twenty years of field research on forest clearing fires in the Brazilian Amazon region. Experiments were conducted in Manaus (state of Amazonas) (2 experiments), Tomé-Açu (state of Pará) (1 experiment), and A...

Identificação e caracterização dos principais tipos funcionais de plantas (TFP) no bioma cerrado para uso em modelos integrados de biosfera terrestre.
Modelos de interação biosfera-atmosfera de última geração, como o modelo integrado de biosfera-IBIS (Integrated Biosphere Simulator), usam a classificação de tipos funcionais de plantas (TFP) para determinar as classes de vegetação que pela sua vez interagem com a camada limite. O IBIS util...

Determinação de ranking para conjuntos de pontos amostrais em modelos digitais de terreno.
Os Modelos Digitais de Terreno (MDT), representados por TIN (Triangulated Irregular Network), são gerados a partir de um conjunto de pontos amostrais irregularmente espaçados. A quantidade de pontos determina a complexidade do modelo, quanto maior a quantidade de pontos maior a complexidade do mod...

Fire-probability maps for the Brazilian Amazonia.
Most fires in Amazonia result from the combination between climate and land-use factors. They occur mainly in the dry season and are used as an inexpensive tool for land clearing and management. However, their unintended consequences are of important concern. Fire emissions are the most important so...

Combined deforestation and fire occurrence in long-term models of forests and savannas in the Brazilian Amazonia.
According to climate and hydrological conditions, large tropical areas would potentially be covered by forests. Remote sensing and field surveys, however, show how these regions may differ from their potential original states because land use, such as logging, agriculture and pastures. Related proce...

Seasonal variability of vegetation and its relationship to rainfall and fire in the Brazilian tropical savanna.
The feedback mechanisms between climate and vegetation have an important role in the dynamics of the biosphere-atmosphere interaction. In this sense, the knowledge of spatial distribution, temporal dynamics and biophysical characteristics of the vegetation types, are important elements to improve th...
