Interplanetary (IP) shocks are perturbations observed in the solar wind. IP shocks correlate
well with solar activity, being more numerous during times of high sunspot numbers. Earth …

One of the most intense geomagnetic storms of recent times occurred on 10–11 May 2024.
With a peak negative excursion of Sym‐H below− 500 nT, this storm is the second largest of …

We examine the relationship between earthquakes and ultralow frequency (ULF) wave
activity in the nighttime ionosphere based on the electric field data in the direct current/ULF …

Interplanetary (IP) shocks are known to cause significant modifications in Earth's
magnetospheric and ionospheric current systems. The sudden enhancement of solar wind …

An analysis of the mechanisms that caused the storm-time effects during two geomagnetic
storms that occurred on 17 March 2013 and 2015 is presented. We used Global Navigation …

Abstract The Equatorial Electrojet (EEJ) is one of the important near‐earth space weather
phenomena which exhibits significant diurnal, seasonal and solar activity variations. This …

The interplanetary magnetic field (IMF) significantly influences the global ionospheric
electrodynamics, but it is still largely unknown the high‐and low‐latitude ionospheric …

During disturbed periods, E region electric fields can cause anomalous Es layer behavior,
which is observed in the digital ionosonde data. To investigate the influence of these electric …

Prompt penetration of convection/overshielding electric fields to equatorial and low latitudes
during the southward/northward turnings of interplanetary magnetic field (IMF Bz) have been …

The plasma density distribution in the equatorial and low latitude ionosphere can often be
severely disturbed during active space weather events that can have paramount impacts on …
