Description
Summary:In recent years, the studies in global electric circuit (GEC) have received additional interest because of its potential to monitor climate and its use in representing the planets electrical subsystem in Earth system models. The new tools and climate models developed recently have improved our insight not only into various atmospheric processes involved in the GEC, but also in their mutual interactions on the local and global scales. The processes occurring within the atmosphere and outside it in space have been observed to influence the Earth's electrical environment. In this article, we summarize the work done in these directions and give some recommendations for better understanding of the GEC. •Reviewed salient features of the DC and AC Global Electric Circuits.•Broadly described effects of climate variability on GECs.•Suggested future studies to test validity of GEC and its relations with climate.
