DRAGON-WEX (the DRake pAssaGe and sOuthern oceaN - Wave EXperiment): a study of gravity waves and tides around Antarctica



Tracy Moffat-Griffin, British Antarctic Survey

The 60Ā°S region is known to be where"missingā" gravity-wave momentum flux in Global Circulation Models gives rise to the significant stratospheric "cold-poleā" problem and one where wave fluxes, sources and variability are poorly known. As part of the UK NERC funded project: DRAGON-WEX (the DRake pAssaGe and sOuthern oceaN - Wave EXperiment) a detailed study of satellite, meteor radar and radiosonde data has been undertaken to determine the gravity waves and tide climatologies in the stratosphere and mesosphere. The results of DRAGON-WEX will be presented alongside results from studies done by the Antarctic Gravity Wave Network (ANGWIN).
