Análise da susceptibilidade a deslizamentos de terra: estudo de caso de Paraibuna, SP
Several places in Brazil with exotic species plantations, such as Eucalyptus, have been increased substantially in recent years, especially by the great demand for wood pulp, coal and construction. In the municipality of Paraibuna-SP, located near to Serra do Mar region, such plantings has developed...

Visible leader propagation during the preliminary breakdown pulse activity preceding a negative cloud-to-ground stroke
The present work consists on the report of one stepped leader event whose initial development becomes visible above cloud base. The leader starts to propagate with speeds of the order of 10^6 m/s simultaneously with the emission of electric field pulses normally associated with the preliminary break...

Spatial patterns of the remaining Atlantic Forest and elements that make up the landscape of the Serra do Mar Paraiba do Sul River Valley: micro-region of Paraibuna-Paraitinga
The landscape of the southeastern Brazilian suffered intense changes due to anthropogenic processes during the last 300 years, which reduced the natural forest area from 81% of the Atlantic Forest Biome to only 8%. Currently, the, situation of this biome are broad areas that had its natural vegetati...

Padrões espaciais dos remanescentes da Mata Atlântica e elementos que compõem a paisagem da Serra do Mar no Vale do Paraíba – microrregião do Paraíbuna-Paraitinga
The intense fragmentation of the Brazilian Atlantic Forest raises some important questions for understanding its spatial dynamics, especially about the relationships between the natural and anthropic elements. Regions of high altitude and rough reliefs, such as Serra do Mar, are well conserved and t...

Analysis of landscape fragmentation and its contributions to the susceptibility to desertification processes in the Sub-Basin Médio Jaguaribe, Ceará
The process of desertification is the focus of many studies, but the association of social aspects in this analysis is still underutilized. The objective of this study is to evaluate the environmental vulnerability to desertification processes in the Hydrographic Sub-basin of the Médio Jaguaribe - ...

Estudo da dispersão de partículas em reservatórios a partir de derivadores rastreados por satélite
Satellite tracked drifters were deployed in order to study the horizontal transport and dispersion in the epilimnion of a large hydroelectric reservoir. Our study was motivated by the dispersion implications on the reservoir surface process, such as larval dispersion, turbulent mixing, point-source ...

Extreme rainfall, vulnerability and risk: a continental-scale assessment for South America
Extreme weather continues to preoccupy society as a formidable public safety concern bearing huge economic costs. While attention has focused on global climate change and how it could intensify key elements of the water cycle such as precipitation and river discharge, it is the conjunction of geophy...

Inter-annual variability of carbon and water fluxes in Amazonian forest, Cerrado and pasture sites, as simulated by terrestrial biosphere models
This study analyzes the inter-annual variability (IAV) of simulations of 21 different land surface model formulations, driven by meteorological conditions measured at 8 flux towers, located in rain forest, forest-savanna ecotone and pasture sites in Amazonia, and one in savanna site in Southeastern ...
