description abstractThe results of partial reflection radiowave wind observations (60-110 km) for four 10-day intervals in 1976 at Saskatoon, Canada (52°N, 107°W), are presented. A harmonic analysis has been applied to data for the four seasons: the means of the semi-diurnal and diurnal components are in reasonable agreement with other measurements at similar latitudes. There are large day-to-day variations in the amplitudes and phases of the tides. The seasonal variations of mean winds (Gregory and Manson, 1975a) are not appreciably altered by the removal of tidal components. Gravity waves with periods ?5 h are identified and the periods are found to vary with the mean background wind. The mechanism involved is not understood. An oscillation with a 2-day period is found in August and a similar oscillation is seen in stratospheric temperatures near 20 km.
