Response of ionospheric disturbance dynamo and electromagnetic induction during geomagnetic storm

Abstract: During geomagnetic storms, the direct penetration of magnetospheric convection electric field and the ionospheric disturbance dynamo (IDD) take place in the ionosphere. In this paper, we studied variability of IDD and electromagnetic induction (EMI) at different latitudinal sectors during the geomagnetic storms on 7 and 8 September 2002 and 20 and 21 November 2003 with high solar wind speed due to coronal mass ejection. This investigation employs geomagnetic field components (H and Z), the geomagnetic indices … Show more

“…The amplification rate of induction might depend on temporal and spatial structure of the ionospheric currents source and distribution of the conductivity in the Earth. The rate of induction analyses during the quiet day variations are associated to the influence of equatorwards penetration of the electric fields from the field-aligned current, Earth conductivities, the effect of the ocean and ionospheric conductivities[44].…”
