2018 Workshop: Whole atmosphere coupling
Different types of waves (gravity waves, tides, and planetary waves) are major dynamical features that couple tropospheric, stratospheric, and mesospheric processes to the upper thermosphere and ionosphere. While the importance of wave forcing from below is without dispute, major challenges remain in understanding the evolution of the wave spectrum in the TI system, including wave-wave and wave-mean flow interactions that excite additional motions and drive the structure, mixing, composition and energy balance in the TI. This workshop aims to discuss our understanding of the roles of different mechanisms, articulate scientific challenges faced by the research community, and identify further steps needed to move forward, including required theoretical, modeling, and observational efforts.
All presentations are 10 min talks + 3 min of discussion; short contributions are 3 slides (5 mins)

Understanding the coupling of different atmospheric regions is the primary goal of the CEDAR community. This workshop will build on the following CEDAR strategic thrusts: Strategic Thrust #1:Encourage and Undertake a Systems Perspective to Geospace; Strategic Thrust #2: Explore Exchange Processes at Boundaries and Transitions Strategic; Thrust #3: Explore Processes Related to Geospace Evolution Strategic; Thrust #5: Fuse the Knowledge Base across Disciplines
