Kinetic effects in solar wind-magnetosphere-ionosphere coupling during extreme magnetic storms
Kinetic effects in solar wind-magnetosphere-ionosphere coupling during extreme magnetic storms
Session ID#: 83234
Session Description:
Under driving conditions leading to extreme magnetic storms, kinetic effects become critically important on global scales. For example, associated with coronal mass ejecta, the interplanetary magnetic field (IMF) can sometimes be primarily along the Sun-Earth line. Such an IMF is quasi-parallel to the surface normal of most of the bow shock, enabling the intense kinetic turbulence generated at the foreshock to impact the magnetosphere globally. The session invites contributions from observations, theories, and simulations to document the importance of kinetic effects in solar-wind-magnetosphere-ionosphere coupling for magnetized planets under extreme driving. The session aims to advance fundamental understanding of cross-scale plasma physics that is at the core of next-generation space-weather modeling. Recent discoveries of high-speed solar-wind jets impinging the magnetopause and ultra-low-frequency waves penetrating into the magnetosphere by THEMIS, Cluster, RBSP, and MMS make the session a timely forum for observations to join hands with global kinetic modeling.
