The generation, propagation, and breaking/disspation of atmospheric gravity waves (GWs) represents a major coupling mechanism that reaches from the boundary layer to the upper atmosphere. In the middle and upper atmosphere the coupling mainly results from GW drag and its effects on the circulation, GW energy deposition, GW mixing of minor constituents, interaction of GWs with planetary waves and thermal tides, and turbulent energy cascades induced by GW breaking. GWs also lead to large fluctuations in winds and temperatures that can create traveling ionospheric disturbances (TIDs). In addition, the spatial and temporal intermittency of GW drag can generate large-scale secondary GWs that propagate to higher altitude. Contributions based on modeling and observations regarding these and other GW-related topics are welcome.
