Lunar influence on equatorial atmospheric angular momentum

P. 163-166.
Bizouard C., Zotov L., Sidorenkov N.

This study investigates the relationship between the equatorial atmospheric angular mo-
mentum oscillation in the non-rotating frame and lunar tidal potential.  Between 2 and 30 days, the
corresponding equatorial component is mostly constituted of prograde circular motions, especially of a
harmonic at 13.6 days, and of a weekly broad band variation. A simple equilibrium tide model explains
the 13.6-day pressure term as result of the lunar tide; the tidal lunar origin of the whole band from 2
to 30 days is attested by speciØc features, not occurring for seasonal band dominated by the solar thermal
effect
