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 field generation in atmospheric convective cells

Journal of Atmospheric and Terrestrial Physics, 1992
Abstract An electric field generation mechanism in the atmosphere, formed by the joint action of friction and gravitational forces upon the charged aerosol particles captured into a convective cell is considered. It is shown that the electric field structure may be found by a self-consistent approach, taking into account the influence of the electric

Measuring atmospheric electric field using novel micromachined sensor

2011 6th IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2011
A new type of micromachined electrostatic field sensor (EFS) that can be used to measure atmospheric field has been demonstrated in this paper. The sensor structure is designed to work at resonant frequency for maximum sensitivity to electric fields. SOI (Silicon on Insulator) micromachining technology was used to fabricate the sensor. The sensing area

Rainbows in strong vertical atmospheric electric fields

Journal of the Optical Society of America A, 1988
The effects of strong vertical atmospheric electric fields and electrically charged raindrops on the primary rainbow are considered. A vertical electric field alters the bow by stretching the raindrops vertically. The effects may be visible only for the extremely large electric fields (E > 105 V m−1) sometimes encountered in thunderstorms. The electric

Atmospheric Electric Field Effects in Cosmic Rays

2004
Discussions on the possible acceleration of charged particles by atmospheric electric fields in periods of thunderstorms started to appear in the scientific literature many years ago. Wilson (1925) assumed that electrons in thunderstorms clouds can be accelerated up to very high energies, as in CR. There were many attempts to observe effects of charged

THE HYPERELECTRIFICATION OF RAINDROPS BY ATMOSPHERIC ELECTRIC FIELDS

Journal of Meteorology, 1956
Abstract 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 ...

Winds and Electric Fields in the Upper Atmosphere

1975
Winds 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.
