Journal ArticleDOI
Lightning and climate: A review
TL;DR: In this paper, the authors summarized research on regional and global lightning activity and the global electrical circuit and summarized that the area of activity has greatly expanded through observations of lightning by satellite and through increased use of the natural (Schumann) resonances of the Earth-ionosphere cavity.

WWLL global lightning detection system: Regional validation study in Brazil
Erin H. Lay,Robert H. Holzworth,Craig J. Rodger,Jeremy N. Thomas,Osmar Pinto,Richard L. Dowden +5 more
TL;DR: In this article, the authors analyzed the performance of the World Wide Lightning Location Network (WWLL) with respect to time, location, and peak current of lightning strokes in Brazil and found that the detected strokes have a location accuracy of 20.25 ± 13.5 km and a temporal accuracy of 0.06 ± 0.2 ms.

The schumann resonance: a global tropical thermometer.
TL;DR: The Schumann resonance, a global electromagnetic phenomenon, is shown to be a sensitive measure of temperature fluctuations in the tropical atmosphere, which increases nonlinearly with temperature in the interaction between deep convection and ice microphysics.

Submonthly Convective Variability over South America and the South Atlantic Convergence Zone
TL;DR: In this article, the relationship between deep convection over South America and the atmospheric circulation is examined, with emphasis on submonthly variations of the South Atlantic convergence zone (SACZ) during austral summer Outgoing longwave radiation (OLR) is used as a proxy for convection, while the associated circulation patterns are depicted by the National Centers for Environmental Prediction Reanalysis Over South America, OLR fluctuations with periods less than 90 days show maximum variance in the SACZ and over central South America during December-February
