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.

Electric fields in the solar atmosphere: A review

Solar Physics, 1991
A review is presented of remote sensing techniques which measure the electric field component transverse to the line of sight and achieve a sensitivity range of 5-10 V/cm. Three models are shown to predict quasistatic, macroscopic values of E(parallel), the electric field component parallel to the magnetic vector, beyond the sensitivity range ...

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

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 ...

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.

Atmospheric response to electric field pulse

Advances in Space Research, 2002
Abstract The complete plasmochemical model was developed for the study of electric field perturbations impact on aeronomy of middle atmosphere and lower ionosphere. The model includes the following set of processes: dissociation, dissociative recombination and dissociative ionization, ionization, excitation, electron attachement and detachement ...

What is the “sign” of the atmospheric-electric field?

Archiv für Meteorologie, Geophysik und Bioklimatologie Serie A, 1962
The sign of the vector representing the atmospheric electric field has recently been subject of debate. For the sake of clarity, it is recommended to refer only to a “normal” or “reversed” clear-weather potential gradient.

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 ...
