Middle atmosphere lunar tides at Saskatoon (52°N, 107°W)
Abstract
Winds have been measured continuously at the Medium Frequency (MF) Radar Observatory at Saskatoon since 1978. A simple analysis has been used to obtain the characteristics of the lunar semidiurnal tide (12.42 h) for summer and winter months. Amplitudes increase with height to 3, 4 ms -1 in summer, winter respectively near 100 km, and the mainly circular tide has vertical wavelengths of ~ 75 km. Comparisons with other observatories and theoretical models are made.
