Pulsations in Global MHD Simulations of the Magnetosphere
Abstract
Pulsations are often observed in the magnetosphere. We report on the varieties of oscillations that we have seen in global, ideal MHD simulations of the Earth's magnetosphere and compare with theory and observations. We discuss the limitations of the model and its spatial and temporal resolution. Both generic and real event simulation results will be presented. In particular, we examine oscillations produced in the simulation by solar wind pressure pulses, IMF transitions, and substorms.
