The terrestrial ring current is an electric current flowing toroidally around the Earth, centered
at the equatorial plane and at altitudes of∼ 10,000–60,000 km. Changes in this current are …

One of the most important issues in space physics is to identify the dominant processes that
transfer energy from the solar wind to energetic particle populations in Earth's inner …

Using the Dst index, more than 1200 geomagnetic storms, from weak to intense, spanning
over three solar cycles have been examined statistically. Interplanetary magnetic field (IMF) …

Abstract Knowledge of the ion composition in the near-Earth's magnetosphere and plasma
sheet is essential for the understanding of magnetospheric processes and instabilities. The …

The magnetic storm is the prime dynamic process in Geospace. It interconnects, in a
uniquely global manner, the solar wind, the magnetosphere, the ionosphere, the upper …

An interdisciplinary NATO Advanced Research Workshop on Effects of Space Weather on
Technology Infrastructure (ESPRIT) was held in Rhodes, Greece, on 25‐29 March 2003 …

On the basis of geomagnetic activity indices and solar wind parameters, a superposed
epoch analysis has been conducted for more than 300 geomagnetic storms. The intensity of …

The interaction between interplanetary shocks and the Earth's magnetosphere manifests in
many important space physics phenomena including particle acceleration. We investigated …

Both solar wind and ionospheric sources contribute to the magnetotail plasma sheet, but
how their contribution changes during a geomagnetic storm is an open question. The source …

A new view of the ring current as an active element in the geospace system has emerged in
which the ring current responds not only to changing convection electric fields imposed by …
