Abstract
One of the grand challenges of Heliophysics today is understanding and ultimately predicting the dynamics of stormtime geospace – the near-Earth space environment spanning altitudes from a few tens to millions of kilometers. Untangling the web of causal connections in stormtime geospace in all its complexity is imperative if we are to predict space weather and its most severe impacts on our technological infrastructure. In this presentation, we review recent results from the NASA DRIVE Science Center for Geospace Storms (CGS), a recently selected NASA research and innovation hub, whose vision is to transform the understanding and predictability of space weather. One of the CGS objectives is to develop a Multiscale Atmosphere-Geospace Environment (MAGE) model with the above challenges in mind. We concentrate on representative examples of physical processes that demonstrate the unique complexity of the cross-scale coupling in stormtime geospace. The examples include mesoscale plasma sheet bursty flows, entropy bubbles and injections of hot plasma into the terrestrial ring current; precipitation of energetic magnetospheric particles into the ionosphere and its effects on local and global electrodynamics; core plasma circulation through the geospace system, especially at mesoscales; transient reconnection at Earth’s magnetopause and its Alfvénic interaction with the ionosphere; the redistribution of mass density in the thermosphere induced by high-latitude energy deposition from the magnetosphere; and effects of lower atmosphere waves and disturbances on the ionosphere-thermosphere. We conclude by placing these representative cross-scale coupling processes in the context of the global mass and energy redistribution characteristic of storm-time geospace dynamics.
