The effect of magnetospheric substorms on the ring current is not completely
understood.  Using a combination of the University of Michigan BAT-S-RUS
Model and Fok Ring Current Model, the effects of multiple substorms on the
ring current were modeled using simulated solar wind data.  In particular I
will discuss how the symmetry and energy of the ring current are different
for multiple substorms as compared to isolated substorms.  I will also
discuss factors that influence size and scope of injections into the ring
current.
