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 ...

Electric Mode Excitation in the Atmosphere by Magnetospheric Impulses and ULF Waves

open access: yesFrontiers in Earth Science, 2021
Variations of vertical atmospheric electric field Ez have been attributed mainly to meteorological processes. On the other hand, the theory of electromagnetic waves in the atmosphere, between the bottom ionosphere and earth’s surface, predicts two modes,

The atmospheric electric field in Athens-Greece

open access: yesMeteorology and Atmospheric Physics, 1997
In the present study, the daily, annual and seasonal variations of the electric field in Athens-Greece, for all weather as well as for fair weather conditions, for the 16-years period 1965–1980 were examined. The daily variation of the electric field follows a double oscillation.

Trends and Features of Thunderstorms and Lightning Activity in the Upper Volga Region

open access: yesAtmosphere, 2023
An increase in the frequency of atmospheric hazards in a changing climate has attracted interest in the study of regional features of mesoscale convective systems and trends of lightning activity. Severe convective storms are the most destructive weather

Isotropic Irradiation Model from Atmospheric Discharges Using Local Atmospheric Electric Field Data

open access: yesBrazilian Archives of Biology and Technology, 2022
Using a local atmospheric electric field sensor network (Field Mill), an electromagnetic link model was proposed considering a free space electric field and a theoretical electric field calculated from an atmospheric discharge. With this, it was possible

Simulation Analysis of Sensors with Different Geometry Used in Measurements of Atmospheric Electricity

open access: yesSensors, 2023
The atmospheric electric current, “air–earth current”, flows between the low ionosphere and Earth’s surface. The source of this current is the potential difference between the global equalizing layer called the ionosphere and the ground surface ...

Semi-Contained Interactions of Atmospheric Neutrinos in the MACRO Detector [PDF]

open access: yes, 2002
Atmospheric neutrinos arise from the decay of particles (primarily pions, muons and kaons) produced in the collision of high energy cosmic ray particles with the atmosphere.

On the Problem of Critical Electric Field of Atmospheric Air [PDF]

open access: yesAtmosphere, 2021
It is traditionally accepted to define the dielectric strength of air as an electric field corresponding to the balance between the rates of impact ionization and electrons’ attachment to neutrals. Its reduced value is known to be about 110 Td regardless of the altitude above the mean sea level.

Lightning risk warnings based on atmospheric electric field measurements in Brazil [PDF]

open access: yesJournal of Aerospace Technology and Management, 2011
This paper presents a methodology that employs the electrostatic field variations caused by thundercloud formation or displacement to generate lightning warnings over a region of interest in Southeastern Brazil.
