Session ID#: 17358

Session Description:
The magnetotail is the major reservoir of the solar wind energy deposited to Earth’s magnetosphere, and the major arena of this energy’s conversion and transport. A significant amount of the conversion and transport (including mass and momentum transports) occurs during dynamic processes. Such processes include the dynamics of thin current sheets, transients (e.g., plasmoids and BBFs), turbulence, waves and their interaction with particles, etc. These processes can be triggered externally by solar wind/magnetosheath/magnetopause changes, or internally within the tail. The processes and their triggers differs dramatically at different tail distances. Due to the fundamental roles of the magnetotail in the entire magnetospheric energy budget, it is important to continuously improve our understanding of the tail dynamic processes. To achieve this goal, this session solicits new findings on the dynamics in the near-earth tail (<30 RE) and mid/distant tail (>30 RE). This session welcomes observations, theories, and numerical modeling/simulations.
