| description abstract | This study presents a climatology of mesospheric and lower-thermospheric diurnal tidal winds obtained with the High Resolution Doppler Imager (HRDI) on the Upper Atmosphere Research Satellite (UARS). The observations reveal that although tidal structures are present at all times, like the prevailing zonal winds, they exhibit significant semiannual as well as other shorter-term variations in amplitude. Results are presented for a period extending over more than one year from November 1991 to July 1993. The 1,1 diurnal tidal amplitude of the meridional component, characterized by the value at an altitude of 90 km and a latitude of 22°, ranges from a minimum at solstice of less than 20 m s?1 to an equinox maximum of over 70 m s?1. The vertical wavelength and phase of the tide show only slight variations throughout the year, with a suggestion of semiannual variations in both. | |
