3-Dimensional MHD Simulation of Solar Wind - Magnetosphere Interaction
and 
Modeling of Magnetosphere - Ionosphere Coupling Precesses

1. QuickTime Movie for Simulation/Modeling

The QuickTime movie files, which were obtained by means of computer
simulation and modeling, are presented in this CD-R. The computer
simulation was created by T. Ogino and the computer modeling by
Dr. J.-H. Shue and Prof. Y. Kamide.

The movie files in movie 1, movie 2, and movie 3 formats represent
simulation/modeling for the January 1997 events (1/10/1997-1/11/1997),
when magnetospheric storms occurred on 1/10 and the solar wind had a
very high density.  Nsw = 185 /cc with a northward interplanetary
magnetic field (IMF) and Bz = 18.2 nT. Ionospheric currents were
calculated using an inverse method (KRM method) when data from
observations of the geomagnetic field was used for the calculation.
A three-dimensional global magnetohydrodynamic (MHD) simulation
of the interaction between the solar wind and the Earth's magnetosphere
was presented for the high density solar wind and northward IMF.

The three-dimensional MHD simulation for the IMF rotation is also
presented in a polar plot format, with three-dimensional magnetic
field lines, cross sectional patterns, and reconnection sites.

Moreover, the MHD simulation results with high spatial resolution
are demonstrated every 30 seconds when the IMF changes its
orientation to the north-south direction.

These QuickTime movie files can be viewed by a large number of people
from workstations and personal computers. We are pleased to provide
them for your enjoyment.

Thank You,
