Determining effects of energy deposition and transport across regions during disturbed times such as storms and substorms is an important objective in the mid and high-latitude M-I-T system. Coupling across scales is also a critical challenge since observation and modeling capabilities for bridging scales are limited. This session solicits presentations on a wide range of coupling processes in the M-I-T system from global to local processes, by all means of observations, modeling and data science. Relevant topics include but are not limited to (1) density and temperature structures (polar cap, plume, trough and irregularities); (2) convection (flow channels and SAPS) and currents; (3) energy transfer and deposition by precipitation, conductivity, aurora (cusp, substorm, STEVE and proton aurora), and heating; (4) ion-neutral interaction (thermospheric density and wind), and (5) driving from and feedback into the magnetosphere. Presentations on the recent severe storms and future missions such as GDC are also encouraged.
