The dynamics of the middle atmosphere and its coupling to the tropospheric weather and climate are inherently tied to a broad spectrum of atmospheric waves. This session will consider theoretical, observational, and modeling (idealized to complex) studies focused on the interactions between waves (gravity waves to planetary scale) with the circulation. Additionally, we will consider presentations that discuss dynamic features of the middle atmosphere, such as the Brewer–Dobson circulation and polar vortices, and their connection to the global atmosphere–ocean system.
