Effect of Multiple Substorms on the Ring Current

The effect of magnetospheric substorms on the ring current is not completely understood. Using a combination of the University of Michigan's BAT-S-RUS Model and Mei-Ching Fok's Ring Current Model, we will study how substorms can affect the ring current. Using simulated solar wind to drive substorms, we will study the effects of multiple substorms on the ring current. In particular we will study how the symmetry and energy of the ring current are different for multiple substorms as compared to a single substorm. We will also study how multiple substorms can drive injections into the ring current.
