Effects of Brazilian large urban areas over lightning. A Review.
The urban effect over the lightning activity is a recent subject. The first works start at the end of the 20th century. After this study, many others studies were made to cities in Europe, USA and Brazil. Apparently the urban effect on lightning activity is a combination of thermodynamic effect (Urb...

Drought diagnostic over Southeastern Brazil during summer 2014 and impacts over the water supply in during summer 2014 and impacts over the water supply in the Cantareira reservoir.
Drought is documented in causing drawdowns of surface reservoirs and impacting water supplies all over the globe. One such documented case occurred in Southern Brazil, over the Cantareira System (CS), one of the largest in the world, as well as one used to supply 8.8 million customers, including met...

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 ...

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...

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...
