Gravity waves play multiple and diverse roles in vertical coupling throughout the atmosphere. Their major sources include orography, convection, frontal systems, jet streams, and secondary generation due to momentum transport and instability dynamics. They transport energy and momentum to higher altitudes affecting the dynamics, structure, and variability of the atmosphere from the stratosphere into the mesosphere and thermosphere, but these processes are still not fully understood.

This session solicits papers focusing on recent measurement programs and modeling studies addressing the full spectrum of gravity wave dynamics from local to global scales. Presentations are encouraged that investigate gravity wave sources, dynamics, propagation in variable environments, instabilities and turbulence, momentum transport and deposition, and multiscale interactions.
