Magnetospheric response of two types in PSc geomagnetic pulsations to interaction with interplanetary shock waves

Interaction of Energetic Ring Current Protons with Magnetospheric Hydromagnetic Waves

Simulation of Shock Waves in the Interplanetary Medium

The shocks in the solar corona and interplanetary (IP) space caused by fast Coronal Mass Ejections (CMEs) are simulated numerically and their structure and evolution is studied in the framework of magnetohydrodynamics (MHD). Due to the presence of three characteristic velocities and the anisotropy induced by the magnetic field, CME shocks generated in the lower corona can have a complex structu...

ULF waves in the solar wind as direct drivers of magnetospheric pulsations

Transient changes in magnetospheric‐ionospheric currents caused by the passage of an interplanetary shock: Northward interplanetary magnetic field case

[1] We use results from a global MHD simulation to study the interaction of an interplanetary shock with the Earth’s magnetosphere for a northward interplanetary magnetic field orientation. We connect intensifications of the transient northward Bz (NBZ) and Region 1 currents in the ionosphere with the appearance of two strong dynamo regions in the magnetosphere: the first on the high‐latitude m...

Interaction of Shock Waves with Magnetic Fields

In continuation of the work on interaction between shock waves and magnetic fields 2 the experiments reported here measured the atomic and electron densities in the interaction region by means of an interferometric and a spectroscopic method. The transient atomic density was also calculated using a one-dimensional theory based on the work of JOHNSON 3, but modified to give an improved physical ...
