Numerical Investigations of Solar Wind-Magnetosphere-Ionosphere Coupling

This project is centered on several problems involving the coupling of mass, momentum, and energy between the solar wind, magnetosphere, and ionosphere. This work involves both the development of new codes and the modification and use of existing codes to address the problem of solar wind-magnetosphere-ionosphere coupling. The emphasis during this period continued to be on magnetosphere-ionosphere coupling during magnetospheric substorms. Specific projects include: a three-dimensional model cast in dipole geometry to model ULF waves in the earth’s magnetosphere; collaboration with the group of Tom Jones (Astronomy) using the three-dimensional MHD TVD code developed by this group to model wave propagation in the geomagnetic tail; and development of a test particle model to use in connection with the fluid codes to investigate auroral particle acceleration.
