Electric fields in the solar atmosphere

Solar Physics, 1977
The gross-structure of the force-free currents in the solar atmosphere and their possible dynamics have been discussed as caused by quasi short-circuited electric fields, generated by the motion of the solar magnetic features.

Lunar phases and atmospheric electric field

Advances in Atmospheric Sciences, 1989
The association between the lunar phases and the atmospheric electric field has been investigated from the superposed epoch analysis of the long series of continuous data of the vertical electric field for Colaba, Bombay (18 ° 53′N, 73 ° 48′E 11 mASL) for the period 1947–1966.

Formation of a local atmospheric electric field

Geomagnetism and Aeronomy, 2011
We have estimated the variations in the atmospheric electrostatic field (AEF, EZ(0)) strength in the surface layer caused by variations in conductivity due to radon influences, cosmic ray intensity, changes in the balance of light and heavy ions during sunset and sunrise, and under the effect of the ionospheric electric current potential on the AEF ...

Variation of atmospheric electric field during aurorae

pure and applied geophysics, 1972
The measured data of the atmospheric potential gradientE during aurorae are summarized. It is shown that aurorae in the northern hemisphere decreaseE, and aurorae in the southern hemisphere increaseE. Depending on aurorae intensities, variations ofE reach 30–35% from the mean.

Electric Field Mill, an Effective Methodology to Measure the Localized Lower Atmospheric Electric Field

Materials Today: Proceedings, 2020
Abstract Atmospheric electric field is an utmost parameter to study the dynamics of earth’s atmosphere. Response of electric field may give the idea of localized atmospheric agitations. Electric field mill monitoring system monitors the atmospheric electric field variations which help to investigate and characterize the atmospheric variability in ...

Electric Fields in the Middle Atmosphere

Physica Scripta, 1987
Middle atmospheric electrodynamics is characterized by discussing the present understanding of the background electrical conductivity and the sources for electric fields and currents within the medium. Results of recent research that contradicts the historical view of the region are presented. Of principal interest to the present direction of the field

Operation of Electric Motors from the Atmospheric Electric Field

American Journal of Physics, 1971
An electret-type electric motor and a corona-type electric motor have been constructed for operation from the earth electric field. The power is delivered to the motors by means of simple earth-field antennas with radioactive or sharp-point collectors. Initial results on the operation of the motors are reported.

Global variation in the atmospheric electric field

pure and applied geophysics, 1972
An analysis of the global nature of the atmospheric electric field is presented on the basis of comparison of measurements on the research vessel, Hakuho-Maru, on the Mid- and South-Pacific Ocean, with those at Syowa Station in Antartica and on two vessels on the Mid-Atlantic Ocean.

Diurnal variations in the atmospheric electric field

Journal of Atmospheric and Terrestrial Physics, 1976
Abstract The diurnal variation of potential gradient at a continental site in the Southern Hemisphere does not follow the established pattern for Northern Hemisphere continental sites, nor does it accord with the diurnal variation found over the oceans and in polar regions. There is good correlation between potential gradient and space charge density

ARES, atmospheric relaxation and electric field sensor, the electric field experiment on NETLANDER

Planetary and Space Science, 2000
Abstract The conditions which prevail in the atmospheres of most planets in the Solar System, in particular the telluric ones, are likely to give rise to their electrification. The resulting processes, which are of major importance for meteorology and climatology on Earth, may also be significant for atmospheric and surface processes on the other ...
