2018 Workshop: Small scale GW dynamics in the MLT
Dave Fritts
Jonathan Snively
This workshop will be dedicated to our late colleague and close friend, Dr. Brian Laughman (3/1/79-2/23/18). Brian contributed 15 years of gravity wave modeling research to the CEDAR community as a graduate student, postdoc, and research colleague. He will be deeply missed.
The workshop will include new modeling, theoretical, and observational studies addressing gravity waves, their dynamics, and influences in the MLT as well as their potential effects above in the thermosphere and ionosphere.

Gravity waves play central roles in MLT dynamics, among them 1) momentum transport from sources at lower altitudes, 2) momentum deposition that defines the seasonal variations of the zonal mean wind and temperature fields, 3) strong interactions with tides planetary and waves, and 4) instabilities and turbulence leading to diffusion and transports of heat, momentum, and species.
While the influences of gravity wave momentum deposition on mean winds is reasonably understood, there remains a need to understand smaller-scale dynamics associated with multi-scale gravity wave interactions, gravity wave breaking, and instabilities and turbulence influences.
