Coupled ocean-atmosphere variations over the south atlantic ocean.
The role of ocean-atmosphere interactions on summer rainfall over the South Atlantic Ocean is explored through the use of coupled ocean-atmosphere models. The Brazilian Center for Weather Forecast and Climate Studies (CPTEC) coupled ocean-atmosphere general circulation model (CGCM) and its atmospher...- por Portal Padrão

Scenarios for solar thermal energy applications in Brazil.
The Solar and Wind Energy Resource Assessment (SWERA) database is used to prepare and discuss scenarios for solar thermal applications in Brazil. The paper discusses low temperature applications (small and large scale water heating) and solar power plants for electricity production (concentrated sol...- por Portal Padrão

Distributed hydrological modeling of a micro-Scale rainforest watershed in Amazonia: model evaluation and advances in calibration using the new HAND terrain model.
Three sections of the Asu catchment, which is located within the Cuieiras Reservation 80 km northwest of Manaus in Central Amazonia, Brazil, were gauged to create nested catchments of the first (0.95 km2), second (6.58 km2) and third (12.43 km2) Strahler orders. As the Cuieiras reserve contains pris...- por Portal Padrão

Climate fields over South America and variability of SACZ and PSA in HadGEM2-ES CMIP5.
Historical simulations (present climate) and projections under RCP8.5 scenario (future climate) by HadGEM2-ES of temperature and precipitation are analyzed during the four seasons in South America. Projections of precipitation are discussed in terms of atmospheric circulation. The South Atlantic Con...- por Portal Padrão

Methods to overcome lightning location system performance limitations on spatial and temporal analysis: brazilian case.
One of the most interesting attributes of Lightning Location Systems (LLSs) data is that they can be analyzed in several ways according to the objectives of the study. However, the quality of the data is governed by the system performance and has some limitations when analyzed at different temporal/...- por Portal Padrão

The Brazilian Amazon.
The Amazon represents one of the most biodiverse regions in the world, much of which is poorly known and highly threatened by conversion to agriculture. Because of the low capacity in the region to conduct science, conduct conservation planning, and enforce laws and regulations, it is also at high r...- por Portal Padrão

Greenhouse gas emissions from hydroelectric reservoirs: what knowledge do we have and what is lacking?
The question that motivated us to write this chapter was How does hydroelectricity production contribute to the global emissions of greenhouse gases?. Here, we present an overview of (i) scientific advances on the topic and (ii) aspects of hydroelectric reservoir ecology in the context of greenhouse...- por Portal Padrão
