| Session Description | Composed of various plasma populations (e.g., plasmasheet, lobe, ring current, plasmasphere, radiation belts), the magnetosphere is divided into different regions featured by their own characteristic temperature or density. These populations interexchange with each other through a variety of physical processes, such as dipolarization, tail injections, wave excitation, plasma transport, particle energization and losses, and particle precipitation down to the atmosphere. Throughout these processes, global electric and magnetic fields not only serve as the driving/controlling role, but also react self-consistently. Thus the magnetospheric dynamics is highly regulated by the coupling among the global fields, charged particles that populate different regions, and various waves that are excited and reside either regionally or globally. Understanding the underlying coupling mechanisms is therefore of particular significance to advance our knowledge of the geospace system and further to realize the space hazard prediction. Fortunately, current satellite missions (MMS, Van Allen Probes, Cluster, Double Star, THEMIS, LANL-GEO, NOAA/POES, GOES) provide unprecedented opportunities for the community to jointly explore and investigate either sequential or circulated coupled physics from the magnetotail to the inner magnetosphere and even down to the ionosphere. In addition, increasingly powerful numerical tools greatly improve our knowledge of the chain effects in the system. This session solicits observational, theoretical, and modeling efforts on understanding various cross-scale coupling mechanisms in the tail-inner magnetosphere, such as magnetotail dynamics (bursty bulk flow, dipolarization, particle injections, etc) and their impact on the inner magnetospheric dynamics (wave generation, particle energization and losses, etc), electrodynamic responses in the ionosphere due to physical processes of magnetospheric origin, and their further feedback effects on the magnetosphere. |
