2022 Workshop: Gravity Waves in the MTI system.
Katrina Bossert
Sharon Vadas
Pavel Inchin
This session seeks to explore topics related to Acoustic, Acoustic-Gravity, and Gravity wave generation, propagation, dissipation, and vertical coupling through the Earth’s atmosphere. These topics include, but are not limited to, source generation mechanisms, multi-layer observations, high-resolution and global modeling, AGW nonlinear processes, dissipation, breaking, turbulence, and secondary wave generation. We aim to have short talks of 10 minutes with a preference for talks aimed at system level studies including multi-instrument observations and modeling.

Closing remarks
Acoustic, Acoustic Gravity, and Gravity waves are important sources of vertical momentum and heat transport in planetary atmospheres. They play a crucial role in defining the structure and circulation of the Earth’s atmosphere and transporting/mixing chemical species. The nature of their deep propagation through all atmospheric layers and their coupling to the Ionosphere facilitate a systems science approach that utilizes combinations of multi-layer observations and detailed modeling. This is relevant to CEDAR Strategic Thrust #1: Encourage and undertake a systems perspective of geospace. Continued study of AGWs is also crucial to understanding the dynamical state of our atmosphere, weather, and climate as the transfer of energy and momentum between the vertical layers. They are integral to CEDAR Strategic Thrust #2: Explore Exchange Processes at Boundaries and Transitions in Geospace.
