Observations of winds in the 60-100 km height range were made at Mawson (68 deg S, 63 deg E) during December 1981 and January 1982 with the MF spaced antenna technique. The prevailing winds are in accord with other recent observations made at high latitudes and show a peak in the zonal wind near 80 km with westward winds of 30 m/s. The meridional winds maximize near 90 km with an equatorward flow of 10 m/s. The diurnal tide components are in reasonable agreement with recent model predictions, especially in phase. The amplitudes tend to be larger than the model values. The semidiurnal tide is not as stable as the diurnal tide and shows evidence for interference effects between different modes.
