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 ...
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 ...
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 ...
The effect of temperature on self-etching adhesive penetration.
(2006-10-01)
The purpose of this study was to investigate the penetration of an aggressive self-etching adhesive system at refrigerated and room temperatures into ground and unground enamel surfaces. Thirty extracted human teeth were ...

Contribution of storm time substorms to the prompt electric field disturbances in the equatorial ionosphere
(American Geophysical Union, 2017-04-18)
This study tries to bring out the fact that storm time substorms can compete and at times significantly contribute to the geomagnetically disturbed time prompt penetration electric field effects on low and equatorial ...
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 ...
Role of IMF By in the prompt electric field disturbances over equatorial ionosphere during a space weather event
(American Geophysical Union, 2017-02-04)
On 7 January 2005 (Ap=40) prompt penetration electric field perturbations of opposite polarities were observed over Thumba and Jicamarca on a few occasions during 13:45–16:30 UT. However, the electric field was found to ...
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 ...
The equatorial electrojet during geomagnetic storms and substorms
(American Geophysical Union, 2015-02-16)
He climatology of the equatorial electrojet during periods of enhanced geomagnetic activity is examined using long‐term records of ground‐based magnetometers in the Indian and Peruvian regions. Equatorial electrojet ...
