The objectives of this session are to invite a discussion about how the new capabilities improve the specification of the energy and momentum inputs and to determine how the I-T system responds at different scales. The session will focus on the following scientific questions: (1) What are the spatial and temporal characteristics of convection and precipitation features in the range of 50-500 km? (2) How do the large-scale and small-scale features interact with the magnetosphere? (3) What are the relative roles the large and small-scale forcings have in producing thermosphere/ionosphere disturbances? (4) How is localized energy input redistributed globally? Example topic areas include (but not limited to) flow bursts, SAPS, and TIDs/TADs using observations, models, and data assimilation technique.</div></div>
