3-Dimensional MHD Simulation of Solar Wind-Magnetosphere Interaction

Computer simulation data of the interaction of the solar wind and the earth's magnetosphere obtained 
by a 3-dimensional global MHD model and the data on use of supercomputing.

As contents, graphic data of the three dimensional global magnetohydrodynamic (MHD) simulation of 
the solar wind-magnetosphere interaction, animation movie, three dimensional visualization (VRML: 
Virtual Reality Modeling Language), computer processing capability for the MHD simulation model, 
example to use HPF (High Performance Fortran) and MPI (Message Passing Interface) in the MHD model.

A three-dimensional global magnetohydrodynamic (MHD) simulation of the interaction between the solar 
wind and the Earth's magnetosphere was presented for several solar wind and interplanetary magnetic 
field (IMF) conditions, such as a high density of the solar wind, large values of the IMF, IMF turns 
from northward to southward or from southward to northward.

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

The Earth's magnetospheric structure is shown for the dipole tilt when the IMF By and Bz components 
exist. Response of the earth's magnetosphere is also demonstrated when the satellite observation is 
used as input of simulation. 
It contributes to a fundamental research of the international space weather program.
