Coupling Processes in Geospace During Enhanced Solar Wind Driving I Posters
Session ID#: 40525
Session Description:
Geospace is a highly coupled system that involves inter-regional and cross-scale interaction processes. Those processes are particularly evident during disturbed conditions driven by enhanced solar wind driving and explosive release of magnetotail energy, which results in storms and substorms. To achieve system-level understanding of the terrestrial space environment, it is essential to understand plasma and energy transport by particles and fields to/from neighboring domains in the magnetosphere-ionosphere-thermosphere system. Examples of those can be found in magnetopause processes, plasma circulation (plume, patches and outflow), particle injection/energization/precipitation, fast flow channels, wave-particle interaction, and field-aligned currents. It is critical to utilize growing capability of observations by multi-satellites and ground-based network such as the Heliophysics/Geospace System Observatory, as well as global/multi-scale simulations, for advancing community's understanding of Geospace dynamics.
This session solicits presentations on a wide range of coupling processes in the Earth's magnetosphere, ionosphere and thermosphere system; including solar wind-magnetosphere interaction, tail-inner magnetosphere interaction, magnetosphere-ionosphere-thermosphere coupling, and global magnetospheric processes. Observations in space and ground, simulations and theory are invited. Recent progresses, future planning and discussion on open questions are welcome.
