Comparison of zonal neutral winds with equatorial plasma bubble and plasma drift velocities
(American Geophysical Union, 2013-03-20)
A one-year dataset spanning March 2011-March 2012 of coincident observations of night time thermospheric zonal neutral winds, equatorial plasma bubble (EPB) velocities, and zonal plasma drifts are used to examine the ...
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 ...
Daytime plasma drifts in the equatorial lower ionosphere
(American Geophysical Union, 2015-10-19)
We have used extensive radar measurements from the Jicamarca Observatory during low solar flux periods to study the quiet time variability and altitudinal dependence of equatorial daytime vertical and zonal plasma drifts. ...
A simulation study on the impact of altitudinal dependent vertical plasma drift on the equatorial ionosphere in the evening
(American Geophysical Union, 2015-02-28)
We carry out a simulation study on the impact of altitudinal dependent plasma drift on the equatorial ionosphere in the evening, under geomagnetically quiet conditions. Our study used the vertical plasma drift velocity ...
Equatorial zonal plasma drifts measured by the C/NOFS satellite during the 2008–2011 solar minimum
(American Geophysical Union, 2013-06-26)
We use the measurements by the Vector Electric Field Investigation (VEFI) on board the Communication/Navigation Outage Forecasting System (C/NOFS) satellite to study the local time and seasonal‐ and longitudinal‐dependent ...
Climatology of F region zonal plasma drifts over Jicamarca
(American Geophysical Union, 2005-12)
We use extensive incoherent scatter radar observations made at the Jicamarca Radio Observatory between 1970 and 2003 to study and model empirically the equatorial zonal plasma drifts near the F region peak using Bernstein ...
Morphology of the postsunset vortex in the equatorial ionospheric plasma drift
(American Geophysical Union, 2014-12-09)
The postsunset vortex in the equatorial ionosphere exhibits clockwise plasma motions after sunset in longitude (time) and altitude coordinates when the equatorial ionosphere is viewed looking northward. We describe the ...
Plasma drifts and polarization electric fields associated with TID‐like disturbances in the low‐latitude ionosphere: C/NOFS observations
(American Geophysical Union, 2016-01-13)
Medium‐scale traveling ionospheric disturbances are often observed at the magnetically conjugate points in the nighttime midlatitude ionosphere. It has been suggested that gravity waves disturb the ionosphere and induce ...
Altitudinal dependence of evening equatorial F region vertical plasma drifts
(American Geophysical Union, 2014-06-06)
We use Jicamarca incoherent scatter radar measurements to study for the first time the altitudinal variations of late afternoon and early night equatorial F region vertical plasma drifts. We also present the initial vertical ...
Storm time equatorial plasma bubble zonal drift reversal due to disturbance Hall electric field over the Brazilian region
(American Geophysical Union, 2016-05-18)
The dynamics of equatorial ionospheric plasma bubbles over Brazilian sector during two magnetic storm events are investigated in this work. The observations were made at varying phases of magnetic disturbances when the ...
