SUMMARY:Exploring gravity wave characteristics over the Southern Andes\, A
 ntarctic Peninsula\, and South Georgia Island - Corwin Wright\, University

DESCRIPTION:Atmospheric gravity waves are one of the most significant dyna
 mical processes in the middle atmosphere. In particular\, they are critica
 lly involved in polar stratospheric cloud formation\, the development of t
 he 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 challeng
 ing to observe and study. In this talk\, I will present observations and m
 odel results from this region\, using a range of satellite\, balloon and g
 round-based instruments. In\nparticular\, I will focus on the Southern And
 es 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.
