Longitudinal, seasonal and solar cycle variation in lunar tide influence on the equatorial electrojet [PDF]

open access: yesAnnales Geophysicae, 2017
It has been well documented that the lunar tidal waves can modulate the ionospheric electrodynamics and create a visible influence on the equatorial electrojet (EEJ). The lunar tide influence gets intensified around noon, primarily during new and full

Modelling Electrodynamics in Saturn's Upper Atmosphere

open access: yes, 2020
Although electrodynamics plays an important role in controlling Saturn's thermospheric circulation and energy balance at high latitudes, less is known about its effects at lower latitudes. Recent observations from the Cassini magnetometer instrument near

Current Understanding of the Equatorial E x B Drift velocities in the African Sector: A Short Review

open access: yesJournal of Nigerian Society of Physical Sciences, 2022
A short review of the pattern and morphology of the equatorial plasma drift velocities, particularly during the evening-time Pre-reversal enhancement (PRE) period in the African region had been presented.

An investigation of solar flare effects on equatorial ionosphere and thermosphere using co-ordinated measurements

open access: yesEarth, Planets and Space, 2019
The response of equatorial ionosphere–thermosphere system to the X3.8 solar flare of January 17, 2005 has been studied using the coordinated measurements of GPS-derived Total Electron Content (TEC), OI 630.0 nm dayglow and magnetic field measurements ...

Signatures of Sudden Storm Commencement on the equatorial thermospheric dayglow

open access: yesJournal of Space Weather and Space Climate, 2019
It has been observed that the OI 630.0 nm dayglow emission over a dip equatorial station, Trivandrum (8.5° N, 77° E, dip 0.5° N), India registered an abrupt increase of ~ 2000 R during the compression phase of the magnetosphere as dictated by a sudden ...

Polar and Equatorial Ionospheric Electrodynamical Coupling Under a Prolonged Northward Bz Interval

open access: yes, 2023
The interplanetary magnetic field (IMF) significantly influences the global ionospheric electrodynamics, but it is still largely unknown the high- and low-latitude ionospheric electrodynamical coupling under long-duration northward IMF Bz (NBz) and By ...

Cavity Quantum Electrodynamics Complete Active Space Configuration Interaction Theory [PDF]

open access: yes, 2023
Polariton chemistry has attracted great attention as a potential route to modify chemical structure, properties, and reactivity through strong interactions between molecular electronic, vibrational, or rovibrational degrees of freedom.

Frisch, Muller and Belot on an Inconsistency in Classical Electrodynamics [PDF]

open access: yes, 2007
This paper follows up a debate as to whether classical electrodynamics is inconsistent. Mathias Frisch makes the claim in Inconsistency, Asymmetry and Non-Locality ([2005]), but this has been quickly countered by Fred Muller ([2007]) and Gordon Belot ...

Solar cycle variations in equatorial ionospheric zonal electric fields near sunrise

open access: yesEarth and Planetary Physics, 2023
In this study, we investigate the solar cycle dependence of the sunrise ionospheric zonal electric fields at the equator under geomagnetically quiet conditions.
