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 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 ...
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 ...
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 ...
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 ...
A real‐time forecast service for the ionospheric equatorial zonal electric field
(American Geophysical Union, 2012-09-18)
The zonal electric field is the primary driver of two important features of the equatorial ionosphere: (1)The Equatorial Ionization Anomaly (EIA), and (2) plasma density irregularities, also known as spread‐F. During ...
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 ...
Can a nightside geomagnetic Delta H observed at the equator manifest a penetration electric field?
(American Geophysical Union, 2013-02-12)
A prompt penetration electric field (PPEF) usually manifests itself in the form of an equatorial ionospheric electric field being in correlation with a solar wind electric field. Due to the strong Cowling conductivity, a ...
Long‐period prompt‐penetration electric fields derived from CHAMP satellite magnetic measurements
(American Geophysical Union, 2013-08-22)
The prompt penetration of the interplanetary electric field to the equatorial ionosphere is conveniently modeled with a frequency‐dependent transfer function. However, long‐period responses (>3 h) of previously estimated ...
Sporadic E layer development and disruption at low latitudes by prompt penetration electric fields during magnetic storms
(American Geophysical Union, 2013-04-11)
An investigation of low‐latitude sporadic E layers during magnetic storms shows that the formation and disruption of these layers are strongly controlled by the magnetospheric electric fields that penetrate to equatorial ...
