Abstract

As part of a collaborative research program between the British Antarctic Survey and Utah State University, an all-sky CCD imager was deployed at Halley Station (76°S) and Rothera Station (67°S), Antarctica and operated for four austral winter seasons (Apr. 2000 - Sept. 2003). The primary goals were:

  • Determination of the climatology of short period (<1 hour) gravity waves at high Antarctic latitudes.
  • Compare high-latitude gravity wave morphology and dynamics to mid-latitude observations.
  • Determine effects of background winds on the observed propagation anisotropy.
  • Investigate the nature of the observed gravity waves (vertically propagating or ducted).
  • Identify dominant wave sources.
  • Estimate associated momentum flux at mesospheric heights.
  • Asses the importance of auroral activity for gravity waves evident at MLT heights.

In this study we have analyzed the spatial and temporal properties of over 400 extensive wave events observed in the NIR OH emission (altitude ~87 km).
