Description
Edmond Dewan had many interests during his career, but his greatest passions were the small-scale dynamics of the atmosphere and his friends. He made contributions in areas ranging from gravity wave sources and universal spectra to turbulence transport and scaling and mesospheric bores. He was insightful and eager to explore and debate. We miss him and his enthusiasm for science. This workshop welcomes contributions in all areas of small-scale dynamics about which Edmond was passionate, including gravity wave sources and propagation, instability and turbulence, and nonlinear dynamics and mesospheric bores.

Workshop Summary
The workshop included contributions from twelve presenters on the highlights of Edmond Dewan's career, gravity wave spectral models, bore and frontal-wave observations and modeling, mesospheric instabilities, coupling mechanisms, and evolving observational methods and facilities. There were approximately 60 attendees, who participated in sometimes lively discussions with the speakers.
