Global variation in the atmospheric electric field
pure and applied geophysics, 1972An 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.

What is the “sign” of the atmospheric-electric field?
Archiv für Meteorologie, Geophysik und Bioklimatologie Serie A, 1962The 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, 1976Abstract 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, 2000Abstract 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 ...

The Atmospheric Electric Field Variations in The Surface Layer
2019 Russian Open Conference on Radio Wave Propagation (RWP), 2019A mathematical model of non-stationary electrical processes in the surface layer of the atmosphere has been constructed and analyzed. An approximate analytical solution of the system of equations of the model is found in the form of an explicit dependence of the electric field strength on time, height and coefficient of turbulent diffusion ...

Effect of an artificial cloud on the atmospheric electric field
Izvestiya, Atmospheric and Oceanic Physics, 2007Preliminary experimental data on the effect of an artificial steam-water cloud (SWC) on the atmospheric electric field are presented. The experiments were conducted on October 12, 2004, on the Kamchatka occurrence of thermal-power waters in the region of the active Mutnov power plant.

Variation of atmospheric electric field during aurorae
pure and applied geophysics, 1972The 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.

Winds and Electric Fields in the Upper Atmosphere
1975Winds and electric fields are in fact some of the oldest problems in the field of atmospheric physics. In 1882 Balfour Stewart suggested that an electrically conducting region may exist in the atmosphere which is moved (winds !) relative to the geomagnetic field of the Earth.

THE HYPERELECTRIFICATION OF RAINDROPS BY ATMOSPHERIC ELECTRIC FIELDS
Journal of Meteorology, 1956Abstract The role of atmospheric electric fields in selectively charging raindrops is analyzed and compared with direct measurements made inside an active thunderstorm. Expressions are developed for the free charge transferred to conducting spheres polarized by an electric field and immersed in an environment in which the positive and negative ionic ...

Operation of Electric Motors from the Atmospheric Electric Field
American Journal of Physics, 1971An 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.
