A decade of radiosonde observations of wind and temperature in the troposphere and lower stratosphere have made it possible to compile a climatology of low-frequency gravity waves above Davis, Antarctica (69S, 78E). Wave characteristics, extracted using wavelet analysis [Zink and Vincent, 2001]…
The upper troposphere and lower stratosphere (UTLS) is a highly coupled region of the atmosphere where radiation, dynamics, clouds and chemical processes interact on a wide variety of spatial and temporal scales. We use a suite of instruments at Davis, Antarctica (69S, 78E)…
