Atmospheric gravity waves are one of the most significant dynamical processes in the middle atmosphere. In particular, they are critically involved in polar stratospheric cloud formation, the development of the southern polar vortex, and the ‘cold pole problem’, a major issue in weather and climate models where the temperature of the polar stratosphere is consistently heavily biased. However, these waves are highly challenging to observe and study. In this talk, I will present observations and model results from this region, using a range of satellite, balloon and ground-based instruments. In particular, I will focus on the Southern Andes and South Georgia Island, two of the largest wave source in the region. Our results highlight the major advantages new observational techniques provide to understanding atmospheric dynamics in this and other regions.
