Coupled MHD-Inner Magnetosphere Simulations of Geomagnetic Storms
Abstract
The adaptive-grid Michigan MHD model (BATSRUS) has been coupled to a new high Rice Convection Model (RCM). This fully coupled code gives the possibility to realistically undertake global MHD simulations of a magnetic storm and the computation of both Region 1 and Region 2 currents. We will review details of the two models and their coupling, and report on the results of our first storm time simulation with the coupled code and show a comparison with observations. We will discuss the global observations provided by arrays of magnetometers which measure the temporal and spatial development of the ring current as well as high latitude global electrodynamic parameters derived from the AMIE and LiMIE data inversion techniques.
