专题简介 (Session Description):

The Earth’s magnetotail is a highly dynamic region containing many transient and localized phenomena, such as bursty bulk flows, dipolarization fronts, flux ropes, field-aligned currents, plasma bubbles, waves and turbulence etc. These phenomena are closely related to magnetic reconnection and magnetospheric substorms that explosively release energy stored in the magnetotail. Studies in the recent decade show that these phenomena are associated with multi-scale process. Energies injected from large-scale process may finally be dissipated in the ion- or electron-scale current filaments, leading to plasma heating and acceleration, and the energy transport from the magnetotail to the inner magnetosphere/ionosphere. Kinetic instabilities generated by unstable particle distributions may in turn cause large-scale topology change. The cross-scale coupling, which plays the key role in energy transport and conversion in the magnetotail, has not been fully understood yet.

This session will focus on recent advances in understanding the multi-scale processes in the Earth’s magnetotail. We encourage submission of the results utilizing measurements from the magnetospheric satellite missions, such as MMS, THEMIS-ARTEMIS, Cluster, Double Star, GEOTAIL etc, and numerical models resolving different scales, such as global magnetohydrodynamic simulations, hybrid simulations and full particle simulations.
