Energetic ion injection and formation of the storm-time symmetric ring current
An extensive study of ring current injection and intensification of the storm-time ring current is conducted with three-dimensional (3-D) test particle trajectory calculations (TPTCs). The TPTCs reveal more accurately the process of ring current injection, with the main results being the following: (1) an intense convection electric field can effectively energize and inject plasma sheet particl...
متن کاملEffect of solar wind pressure enhancements on storm time ring current asymmetry
[1] The effect of solar wind pressure enhancements on storm time ring current asymmetry is investigated by examining the asymmetric variations in the north-south (H) and east-west (D) components of the geomagnetic field during four magnetic storms. For two strong storms, on 25 September 1998 and 29 May 2003, pressure enhancements occurred during the main phase with strong and steadily southward...
متن کاملModeling ring current ion and electron dynamics and plasma instabilities during a highspeed stream driven storm
[1] The temporal and spatial development of the ring current is evaluated during the 23–26 October 2002 high-speed stream (HSS) storm, using a kinetic ring current-atmosphere interactions model with self-consistent magnetic field (RAM-SCB). The effects of nondipolar magnetic field configuration are investigated on both ring current ion and electron dynamics. As the self-consistent magnetic fiel...
متن کاملAnalytical study of the energy rate balance equation for the magnetospheric storm - ring current
We present some results of the analytical integration of the energy rate balance equation, assuming that the input energy rate is proportional to the azimuthal interplanetary electric ®eld, Ey , and can be described by simple rectangular or triangular functions, as approximations to the frequently observed shapes of Ey , especially during the passage of magnetic clouds. The input function is al...
متن کاملMagnetically self-consistent ring current simulations during the 19 October 1998 storm
[1] We investigate effects of magnetic self-consistency on ring current development by calculating equatorial particle transport in a model that feeds back the ring current on the magnetospheric configuration. The equatorial magnetic intensity is computed by solving a force-balance equation in the equatorial plane. This force-balance computation is coupled to a kinetic proton and electron drift...
