Effect of geomagnetic storm conditions on the equatorial ionization anomaly and equatorial temperature anomaly

Journal of Atmospheric and Solar-Terrestrial Physics, 2018
Abstract The effect of the geomagnetic storm on the equatorial ionization anomaly (EIA) and equatorial temperature anomaly (ETA) has been studied using the atomic oxygen dayglow emissions at 577.7 nm (OI 557.7 nm) and 732.0 nm (OII 732.0 nm). For the purpose of this study, four intense geomagnetic storms during the ascending phase of solar cycle 24 ...

Recent developments in the understanding of equatorial ionization anomaly: A review

Journal of Atmospheric and Solar-Terrestrial Physics, 2018
Abstract A brief review of the recent developments in the understanding of the equatorial plasma fountain (EPF) and equatorial ionization anomaly (EIA) under quiet and active conditions is presented. It is clarified that (1) the EPF is not upward ExB plasma drift at the equator followed by downward plasma diffusion, but it is field perpendicular ExB ...

Role of the equatorial ionization anomaly in the development of the evening prereversal enhancement of the equatorial zonal electric field [PDF]

Journal of Geophysical Research: Space Physics, 2009
During the evening prereversal enhancement of the zonal electric field (EPRE) that begins around 1700 LT when the F region neutral winds turn eastward, as assumed here, and continues till the postsunset zonal electric field reversal time, an overall positive feedback is shown to occur between the eastward electric field in the lower side of the flux ...

Role of equatorial ionization anomaly in the initiation of equatorial spread F

Journal of Geophysical Research: Space Physics, 1988
A comparative study is made of the changes in the latitudinal structure of the F region electron density at fixed altitudes in the Indian equatorial region on days with and without postsunset onset of equatorial spread F, using (N‐h) profile data of Ahmedabad (dip latitude 18.6°N), Waltair (dip latitude 10.6°N), and Kodaikanal (dip latitude 1.5°N).
