Long‐duration penetration of the interplanetary electric field to the low‐latitude ionosphere during the main phase of magnetic storms
(American Geophysical Union, 2005-11-26)
It is well known that the interplanetary electric field can penetrate to the low‐latitude ionosphere. It is generally believed that the penetration of electric fields can last only for ∼30 min because of the shielding ...
Longitudinal variations of positive dayside ionospheric storms related to recurrent geomagnetic storms
(American Geophysical Union, 2013-10-31)
We have performed an analysis of case events and statistics of positive ionospheric storms in the dayside region of the equatorial ionization anomaly during recurrent geomagnetic storms (RGSs), which dominate in geomagnetic ...
Specification of the occurrence of equatorial ionospheric scintillations during the main phase of large magnetic storms within solar cycle 23
(American Geophysical Union, 2010-10-05)
Satellite communication and navigation systems operating at low latitudes suffer outages due to ionospheric scintillations during large magnetic storms that are not currently specified by any model. This paper describes ...
A case study of ionospheric storm effects during long‐lasting southward IMF Bz‐driven geomagnetic storm
(American Geophysical Union, 2014-08-27)
Multiple instrumental observations including GPS total electron content (TEC), foF2 and hmF2 from ionosondes, vertical ion drift measurements from Communication/Navigation Outage Forecasting System, magnetometer data, and ...
Evolution of equatorial ionospheric bubbles during a large auroral electrojet index increase in the recovery phase of a magnetic storm
(American Geophysical Union, 2006-02-10)
We present a model and observations of the evolution of equatorial ionospheric bubbles during a large auroral electrojet (AE) index increase in the recovery phase of a geomagnetic storm. Using a three‐dimensional time‐dependent ...
Effects of disturbed electric fields in the low‐latitude and equatorial ionosphere during the 2015 St. Patrick's Day storm
(American Geophysical Union, 2016-09-02)
The 2015 St. Patrick's Day geomagnetic storm with SYM‐H value of −233 nT is an extreme space weather event in the current 24th solar cycle. In this work, we investigated the main mechanisms of the profound ionospheric ...

Ionospheric Response to the Magnetic Storm of 22 June 2015
(Springer, 2018-08)
A global study is made of the response of the total electron content of the ionosphere (TEC) to the geomagnetic storm occurred on 22 June 2015 (one of the strongest geomagnetic storms of the current Solar Cycle 24). Using ...
Inclination of the geomagnetic field measured by an incoherent scatter technique
(American Geophysical Union, 1971-01-01)
A technique to measure the direction of the geomagnetic field by using incoherent scatter techniques is described. The technique has been used to measure the inclination of the magnetic field at the Jicamarca Radar Observatory ...
