Wind measurements in the mesosphere and lower thermosphere obtained with a medium frequency (MF) radar in Hawaii (22°N, 160°W) spanning ∼16 years are employed to examine the intra‐annual and interannual variability of the mean and tidal motions at altitudes between 84 and 94 km. Intra‐annual periodi...
