Interplanetary drivers of ionospheric prompt penetration electric fields
(Elsevier, 2010-02-10)
In this paper we discussed the penetration effects of common interplanetary magnetic cloud (MC) structures like sheath region, both sheath and magnetic cloud boundary layer (MCBL), MC body, and shock-running into a preceding ...
Penetration characteristics of the interplanetary electric field to the daytime equatorial ionosphere
(American Geophysical Union, 2008-12-23)
Using 8 years of ionospheric drift measurements from the low‐latitude JULIA (Jicamarca Unattended Long‐term Investigations of the Ionosphere and Atmosphere) radar and the solar wind and interplanetary magnetic field data ...
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 ...
Relating the interplanetary-induced electric fields with the low-latitude zonal electric fields under geomagnetically disturbed conditions
(American Geophysical Union, 2013-03-21)
The overall ionospheric variability with periods ranging from long-term, secular changes to days, hours, and even minutes and seconds, is influenced by the solar activity, geomagnetic activity, and processes originating ...
Penetration electric fields: Efficiency and characteristic time scale
(Elsevier, 2007-07)
Penetration of the interplanetary electric field (IEF) to the middle- and low-latitude ionosphere has been investigated for nearly four decades. Most previous studies focused on the correlation between the interplanetary ...
Interplanetary electric fields and their relationship to low-latitude electric fields under quiet and disturbed conditions
(Elsevier, 2007-07)
Recent studies have demonstrated that ground-based magnetometer observations can be used to infer realistic, daytime vertical E×B drift velocities in the Peruvian and Philippine longitude sectors. It has also been demonstrated ...
On the local time dependence of the penetration of solar wind-induced electric fields to the magnetic equator
(European Geosciences Union, 2009-08-05)
For a period of a few hours, the penetration of electric fields of solar wind origin is at its highest efficiency. In November 2003, five days of continuous vertical drift data were obtained at the Jicamarca Radio Observatory. ...
Multi-longitude case studies comparing the interplanetary and equatorial ionospheric electric fields using an empirical model
(Elsevier, 2007-03)
Electric fields have been determined at three longitudes corresponding to Peru, India, and the Philippines. We compare these fields to applying a frequency-dependent linear transfer function (TF) to the dawn-to-dusk component ...
Unusually long lasting multiple penetration of interplanetary electric field to equatorial ionosphere under oscillating IMF Bz
(American Geophysical Union, 2008-01-17)
During November 11–16, 2003, the interplanetary magnetic field (IMF) Bz oscillated between northward and southward directions, which suggests discontinuous magnetic reconnection associated with the multiple pulses‐like ...
By‐dependent prompt penetrating electric fields at the magnetic equator
(American Geophysical Union, 2002-04-13)
We propose a new type of prompt penetrating electric field effect which seems to be related to the y‐component of the interplanetary magnetic field and the NBZ current system. We report an equatorial electric field pattern ...
