The Global Electric Circuit and Global Seismicity [PDF]
Geosciences, 2021 Basing on the catalogue of earthquakes with a magnitude of M ≥ 4.5 for the period 1973–2017, a UT variation with an amplitude of ~10% in the number of earthquakes is revealed and compared with a UT variation in the ionospheric potential (IP) with an ...

The atmospheric global electric circuit: An overview [PDF]
Atmospheric Research, 2007 Research work in the area of the Global Electric Circuit (GEC) has rapidly expanded in recent years mainly through observations of lightning from satellites and ground-based networks and observations of optical emissions between cloud and the ionosphere. After reviewing this progress, we critically examine the role of various generators of the currents

Some Recent Key Aspects of the DC Global Electric Circuit
AtmosphereThe DC global electric circuit, GEC, was conceived by C.T.R. Wilson more than a century ago. Powered by thunderstorms and electrified shower clouds, an electric current I ~1 kA flows up into the ionosphere, maintaining the ionospheric potential V ~250 kV

Brief Communication: Earthquake–cloud coupling through the global atmospheric electric circuit [PDF]
Natural Hazards and Earth System Sciences, 2014 We illustrate how coupling could occur between surface air and clouds via the global electric circuit – through Atmospheric Lithosphere–Ionosphere Charge Exchange (ALICE) processes – in an attempt to develop a physical understanding of the possible ...

Mathematical Simulation of the Ionospheric Electric Field as a Part of the Global Electric Circuit [PDF]
Surveys in Geophysics, 2018 Electric currents flowing in the Global Electric Circuit are closed by ionospheric currents. A model for the distribution of the ionospheric potential which drives these currents is constructed. Only the internal electric fields and currents generated by thunderstorms are studied, and without any magnetospheric current sources or generators.

Behind the curve: a comparison of historical sources for the Carnegie curve of the global atmospheric electric circuit [PDF]
History of Geo- and Space Sciences, 2020 The “Carnegie curve” describes the diurnal variation of the global atmospheric electric circuit. It was originally found from atmospheric electric potential gradient (PG) measurements made on the Carnegie, effectively a floating atmospheric electrical ...

Electromagnetic Atmosphere-Plasma Coupling: The Global Atmospheric Electric Circuit [PDF]
Space Science Reviews, 2011 A description is given of the global atmospheric electric circuit operating between the Earth’s surface and the ionosphere. Attention is drawn to the huge range of horizontal and vertical spatial scales, ranging from 10−9 m to 1012 m, concerned with the many important processes at work.

Empirical evidence for multidecadal scale global atmospheric electric circuit modulation by the El Niño-Southern Oscillation [PDF]
Environmental Research Letters, 2022 The El Niño-Southern Oscillation (ENSO) modifies precipitation patterns across the planet. Charge separation in disturbed weather and thunderstorms drives the global atmospheric electric circuit (GEC), hence ENSO-induced precipitation changes are ...

Extensive layer clouds in the global electric circuit: their effects on vertical charge distribution and storage. [PDF]
Proc Math Phys Eng Sci, 2020 A fair weather electric field has been observed near the Earth’s surface for over two centuries. The field is sustained by charge generation in distant disturbed weather regions, through current flow in the Global Electric Circuit.
