Anomalous radon emanation linked to preseismic electromagnetic phenomena [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2007
Anomalous emanation of radon (<sup>222</sup>Rn) was observed preceding large earthquakes and is considered to be linked to preseismic electromagnetic phenomena (e.g.

Monte Carlo simulations of air showers in atmospheric electric fields [PDF]

open access: yes, 2009
The development of cosmic ray air showers can be influenced by atmospheric electric fields. Under fair weather conditions these fields are small, but the strong fields inside thunderstorms can have a significant effect on the electromagnetic component of

Near-surface atmospheric electric field changes through magnetic clouds via coronal mass ejections

open access: yesGeoscience Letters, 2023
The Earth’s electrical environment is influenced by both external and internal driving factors. Internal driving factors include the global charging current produced by lightning storms, global aerosol concentrations and cloud coverage.

The electrical activity of Saharan dust as perceived from surface electric field observations [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
We report on the electric field variations during Saharan dust advection over two atmospheric remote stations in Greece, using synergistic observations of the vertical atmospheric electric field strength (Ez) at ground level and the lidar-derived ...

The enhancement of droplet collision by electric charges and atmospheric electric fields [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
Abstract. The effect of electric charges and atmospheric electric fields on droplet spectrum evolution is studied numerically. Collision efficiencies for droplet pair with radii from 2 to 1024 μm and charges from −32 r2 to +32 r2 (in unit of elementary charge, droplet radius r in unit of μm) in different strength of downwards electric fields (0, 200 ...

Inversion of a Thunderstorm Cloud Charging Model Based on a 3D Atmospheric Electric Field

open access: yesApplied Sciences, 2018
The measurement of the atmospheric electric field is of great significance for the study of thunderstorm cloud charge models. Traditional electric field meters can only measure the vertical component of the atmospheric electric field, and thus it is ...

Influences of cosmic radiation, artificial radioactivity and aerosol concentration upon the fair-weather atmospheric electric field in Lisbon (1955–1991) [PDF]

open access: yes, 2006
The atmospheric electric field is influenced by cosmic radiation, radioactivity and aerosols. In this work we investigate the existence of: (i) correlations between relative anomalies of annual values of atmospheric electric field and cosmic radiation ...
