摘要：

Satellite wind observations from the High Resolution Doppler Interferometer (HRDI) instrument on;;the Upper Atmosphere Research Satellite (UARS) are used to describe the latitudinal structure and seasonal variation of the terdiurnal (8 hour) atmospheric tide at 95 km. The amplitude of the annual average tide is 5 m/s (meridional) and 15 m/s (zonal). Within the range observed (60 degrees S to 60 degrees N), the maximum amplitudes are found during fall and winter at midlatitudes. Only weak temporal correlations with the diurnal and semidiurnal tides are seen on the monthly time scales resolved.
