Abstract:
Numerical modeling of space weather in geospace presents a formidable challenge due both to its physical and numerical complexity. On the one hand, stormtime geospace exhibits some of the most complex and least understood interactions in space physics. On the other hand, this complexity is in large part due to both the cross-scale and cross-domain nature of these interactions, which requires that any model of stormtime geospace include all of its key regions while resolving all of the critical scales. In this presentation, we will review recent work by the team of the NASA DRIVE Center for Geospace Storms on the development of such a model that we call the Multiscale Atmosphere-Geospace Environment (MAGE) model. The mesoscale-resolving capabilities of MAGE across the domains of geospace will be demonstrated by way of example of several processes with major space weather consequences. These examples will include: the build-up of the radiation belts by mesoscale plasmasheet transport, studied in conjunction with the Van Allen Probes science team; intense localized geomagnetically induced currents due to magnetotail dipolarizations; F-region ionosphere polar cap density patches; and travelling ionospheric and atmospheric disturbances. We will also demonstrate a recent development of an interactive web-based user interface for remote three-dimensional analysis of our simulations, developed as part of the Van Allen Probes science gateway. We will conclude with a discussion of further steps that need to be taken to ensure a more self-consistent representation of stormtime geospace in community models.
