Storm-time equatorial thermospheric dynamics and electrodynamics
(Utah State University, 2020)
It presents the first comprehensive study of the equatorial thermospheric dynamics and ionospheric electrodynamics over Peru following enhanced energy depositions into the high-latitude ionosphere during geomagnetic storms. ...
Electrodynamics in the low and middle latitude ionosphere: a tutorial
(Elsevier, 2004-03-24)
Electric fields in the low and middle latitude ionosphere result from currents driven internally by neutral winds and gravity, and externally by applied potentials. The resulting internal electric polarization fields arise ...
Solar-wind magnetosphere effects in the middle and low latitude ionosphere
(2004-01-01)
Ionospheric electric fields play fundamental roles in the dynamics of the Earth's ionosphere and thermosphere. Enhanced geomagnetic activity has long been known to cause large ionospheric electric field and current ...
Lunar tidal effects in the electrodynamics of the low latitude ionosphere
(Elsevier, 2013-02-04)
The low latitude ionosphere is highly variable over a large range of temporal and spatial scales even during geomagnetically quiet periods, largely as a result of electrodynamic plasma drift effects. Several recent ...
Enhanced lunar semidiurnal equatorial vertical plasma drifts during sudden stratospheric warmings
(American Geophysical Union, 2011-11-15)
Large scale electrodynamic and plasma density variations in the low latitude ionosphere have recently been associated with sudden stratospheric warming (SSW) events. We present empirical models of largely enhanced lunar ...
Low latitude storm time ionospheric electrodynamics
(Elsevier, 2002-04-30)
The response of the low latitude ionosphere to high latitude convection has long been the subject of considerable interest. Radar, ionosonde, magnetometer, and satellite measurements have been extensively used for studying ...
Equatorial ionospheric electrodynamic perturbations during Southern Hemisphere stratospheric warming events
(American Geophysical Union, 2013-03)
We use ground-based and satellite measurements to examine, for the first time, the characteristics of equatorial electrodynamic perturbations measured during the 2002 major and 2010 minor Southern Hemisphere sudden ...
Lunar tidal effects in the electrodynamics of the low-latitude ionosphere
(Utah State University, 2013)
We used extensive measurements made by the Jicamarca Unattended Long-Term Investigations of the Ionosphere and Atmosphere (JULIA) and Incoherent Scatter Radar (ISR) systems at Jicamarca, Peru during geomagnetic quiet ...
Vertical ionization drifts in the lower equatorial ionosphere and the meridional current systems
(American Geophysical Union, 1976-03-01)
Recent radar observations near the magnetic equator show that the electron vertical drift velocity below 200 km is upward during the day and downward at night, in agreement with measurements made at higher heights. The ...
Theoretical effects of geomagnetic activity on low-latitude ionospheric electric fields
(American Geophysical Union, 2005-05-27)
The influence of geomagnetic activity on middle‐ and low‐latitude thermospheric winds and ionospheric electric fields is investigated using model results from the National Center for Atmospheric Research Thermosphere‐Ion ...
