Impacts of Extreme Ultraviolet Late Phase of the Solar Flare on Ionospheric Electrodynamics

Astrophysical Journal Letters
Previous investigations of ionospheric electrodynamical responses to solar flares primarily focused on the main phases (MPs) of solar flares. Typical solar irradiance models for driving global ionosphere models do not include the extreme ultraviolet (EUV)

Solar Flare Impacts on Ionospheric Electrodynamics

, 2012
The sudden increase of X-ray and extreme ultra-violet irradiance during flares increases the density of the ionosphere through enhanced photoionization.

Interdecadal Sea Surface Temperature Variability in the Equatorial Pacific Ocean. Part II: The Role of Equatorial/Off-Equatorial Wind Stresses in a Hybrid Coupled Model

, 2008
Many modeling studies have been carried out to investigate the role of oceanic Rossby waves linking the off-equatorial and equatorial Pacific Ocean. Although the equatorial ocean response to off-equatorial wind stress forcing alone tends to be relatively

Effects of energetic electrons on the electrodynamics in the ionosphere [PDF]

, 2004
International audienceFrom the observations by the PIXIE and UVI cameras on board the Polar satellite, we derive global maps of the precipitating electron energy spectra from less than 1keV to 100keV.

Cosmology and Electrodynamics

, 1968
THE approach of Hoyle and Narlikar1 to quantum electrodynamics provides a good explanation of spontaneous emission, and leads to an expression for the emission rate which is in agreement with the observed rate S, provided that the zero-point oscillations

Remarks on nonlinear electrodynamics [PDF]

, 2014
We consider both generalized Born–Infeld and exponential electrodynamics. The field energy of a point-like charge is finite only for Born–Infeld-like electrodynamics.

An empirical model of ionospheric total electron content (TEC) near the crest of the equatorial ionization anomaly (EIA)

Journal of Space Weather and Space Climate, 2016
We present a geomagnetic quiet time (Dst > −50 nT) empirical model of ionospheric total electron content (TEC) for the northern equatorial ionization anomaly (EIA) crest over Calcutta, India.
