Scope | Determining the effects of energy deposition and transport, and momentum exchange across different spatial and temporal scales is an important objective in the M-I-T system, due to the clear evidence of multi-scale forcing. Coupling over multiple scales is also a critical challenge since observational and modeling methodologies for bridging different scales do not presently exist. This session solicits presentations on a wide range of coupling processes in the high-latitude M-I-T system from global to small-scale processes and related solar wind forcing. Relevant topics include (but are not limited to) (1) density structures and temperature gradients (polar cap, cusp, plume, trough, irregularities); (2) convection (flow channels, SAPS) and FAC; (3) energy transfer and deposition by precipitation and ULF waves, conductivity, aurora, and heating; and (4) coupling and feedback into the magnetosphere. Discussions of relevant multi-scale observations by means of multiple instruments, including space and ground-based, modeling and data science are encouraged. | |
