Measuring the geo-electric field becomes important in understanding the global electric circuit and how it is affected by other phenomena. It is also useful in assessing how the global electric circuit variations can affect climate.
A superposed epoch analysis of variations of the vertical electric field measured at Vostok (78.51S, 1071E; magnetic … latitude 83.61S) during 1998–2002 heliocentric current sheet (HCS)…
Global thunderstorm activity maintains a variable potential difference … of the order of 250 kV between the quasi-equipotentials of the lower … reaches of the ionosphere and the Earth.
Vertical geoelectric eld measurements at Vostok,Antarctica (78:5ºS ;107ºE;corrected geomagnetic latitude,83:4ºS) made during 1998 are compared with both Weimer (1996)and IZMEM (1994)model calculations of the solar-wind-induced, polar-cap potential di erences with respect to the station.
