Space weather influences on atmospheric electricity
Atmospheric electricity is a venerable topic of geophysical science, dating back to the 1750s when Franklin and Dalibard established the presence of electricity in thunderstorms. Subsequently even fine conditions were observed to be electrified, and a downward vertical atmospheric electric field of magnitude ~100V/m observed near the surface during fair weather conditions. The origin of the “fa...
متن کاملAtmospheric Electricity and Cloud Microphysics
The terrestrial atmospheric electrical system covers a range of dimensional scales, from charged molecular clusters to convective cloud systems. Charge-exchange associated with thunderclouds leads to positive charge in the upper conductive regions of the atmosphere and a net negative charge on the planetary surface. In non-thunderstorm regions, a vertical ionic current flows, replenishing the a...
متن کاملMeasurement of Worldwide Diurnal Atmospheric Electricity Variations
An evaluation is made of techniques that have been or could be employed to determine the existence and nature of worldwide variations in atmospheric electric phenomena. I n the course of a discussion of surface measurements, data from six sites on the surface of thc earth are presented. The use of airborne vehicles in studies of global phenomena is discussed and results from soundings and trans...
متن کاملGlobal Electric Circuit and Lower Atmospheric Electricity
This short report describes some recent results of global electric circuit investigations. The experimental foundation of global electric circuit conception is discussed. The main origins of global electric circuit formation are examined. The electrodynamical properties of fair-weather electricity are characterized with standpoint of universal spectra and aeroelectrical structure availability. ...
متن کاملLord Kelvin ’ s atmospheric electricity measurements
Lord Kelvin (William Thomson) made important contributions to the study of atmospheric electricity during a brief but productive period from 1859–1861. By 1859 Kelvin had recognised the need for “incessant recording” of atmospheric electrical parameters, and responded by inventing both the water dropper equaliser for measuring the atmospheric potential gradient (PG), and photographic data loggi...
