AB: Recently, several coupled models of the magnetosphere-ionosphere-thermosphere system have been developed. Although they have been applied in a general sense to study aspects of coupling in an idealized sense, there is a need for them to be applied to specific events so that their predictions can be tested and understood in the context of the observed ionosphere. The coupled thermosphere-ionosphere magnetosphere (CMIT) model is used in this study to simulate the behavior of the low latitude thermosphere and ionosphere during one such event. The behavior of a number of parameters that effect electron density are studied and an analysis of the evolution of the physics that affects electron densities has been undertaken. Amongst the results of this study is the observation that the relative importance of the various physical terms evolves during the storm.
