Simulações e projeções climáticas regionais sobre a América do Sul.
The objective of this study is to assess the climate simulations and projections over South America using the regional climate Eta Model driven by fully coupled Earth System Model HadGEM2-ES of the Met Office Hadley Centre. The HadGEM2-ES was designed to run the major scenarios for IPCC AR5 and comp...- por Portal Padrão

Meteorological aspects of two modes of Lightning-Triggered Upward Lightning (LTUL) events in sprite-producing MCS.
Upward lightning from tall objects can be either self-initiated (SIUL), that is, leaders originating due to locally strong electric fields but without any preceding lightning, or triggered by prior lightning discharges in the general vicinity, termed lightning-triggered upward lightning (LTUL). The ...- por Portal Padrão

Characteristics of lightning emission near infrared observed in Brazil.
Electromagnetic emissions from lightning flashes are observed by a slitless spectrum spectrograph. A Phantom V9.1 high-speed camera is used with a spatial resolution of 1632 x 400 pixels, at 3000 fps and exposure time of 330 μs. A grism (diffraction grating plus prism) that has 600 lines/mm and a s...- por Portal Padrão

Nutrient cycling in rainfall, throughfall and stemflow in Brazilian semiarid region: dry year x rainy year.
Rainfall brings nutrient from atmosphere to the ground scavenging them from the atmosphere column. Furthermore, throughfall washout material deposited on plant tissues as well as leachates exudate products resulting in changes in the rainwater chemistry. Inputs of nutrients into the soil through suc...- por Portal Padrão
