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]…

A consequence of the wave-number rich tidal activity that has been observed in the southern polar MLT is that the horizontal flux of horizontal momentum (u'v') is likely to be non-zero. This quantity is affected by the phase angle between the zonal and meridional wind perturbations.
