Description:

Gravity waves have long been known as a critical driver of the general circulation of the middle and upper atmosphere through their ability to transport significant energy and momentum upwards from multiple tropospheric sources. Their role in modulating temperature, wind patterns, and chemical composition has a profound impact on climate, weather, and the overall behavior of the middle atmosphere. Despite their importance, understanding the sources, propagation, and dissipation effects of these waves from theory and observations and implementing this into global models has been a major challenge in recent decades. 

In this session, we welcome abstracts on new developments (both physics- and machine-learning-based)  in gravity wave science from observations, modeling, and theory, including coupling to surface weather below and space weather in the ionosphere and thermosphere above. In all these areas, we strongly encourage and highlight validation studies that seek to compare observed gravity waves and their associated impacts in the middle atmosphere with predictions from relevant theories, models, or parameterization schemes.
