Coupling between the lower and upper atmopshere/ionosphere via gravity waves.


In this workshop, we explore the propagation, dissipation, and influences of atmospheric gravity waves in the mesosphere, thermosphere and ionosphere. We include any source of gravity waves at any latitude/longitude. We emphasize studies which combine modeling results with observations in order to further our understanding of the coupling between these different regions. However, purely modeling and/or experimental studies are also welcome.

Atmospheric gravity waves provide an important mechanism for transporting energy and momentum from the lower atmosphere to the middle and upper atmosphere that can influence the global circulation and structure of the atmosphere. In addition, in-situ breaking and dissipation of primary waves can generate secondary waves that can continue to propagate to higher altitudes making identifying wave sources difficult. As such, understanding and tracking the propagation of waves from their sources, throughout the vertical layers of the atmosphere, to their dissipation is an important and challenging area of study. Observations are often limited to specific layers, locations, and resolution while modeling studies can simulate the propagation throughout the atmosphere but require suitable constraints of sources and spectra from observations. Overcoming this limitation requires the use of multi-site/mulit-layer observations and data alongside well constrained modeling studies that can fill in the gaps.

The objective of this session is to leverage modeling, theory and multi-site/multi-instrument observational studies of gravity waves that elucidate coupling between different layers of the atmosphere and to their sources mechanisms in order to enhance our understanding of the gravity wave lifecycle and subsequent spectra and influences at different altitudes.
