abstract = "Using OI6300 airglow images collected over Sao Joao do Cariri (7.4
degrees S, 36.5 degrees W) from 2000 to 2007, the equatorial
plasma bubble (EPB) zonal drifts were calculated. A strong
day-to-day variability was observed in the EPB zonal drifts, which
is directly associated with the very complex dynamics of the
nighttime thermosphere-ionosphere system near the Equator. The
present work investigated the contribution of the semidiurnal
lunar tide M-2 for the EPB zonal drifts. The M-2 presented an
amplitude of 3.1 m s(-1) in the EPB zonal drifts, which
corresponds to 5.6 % of the average drifts. The results showed
that the M-2 amplitudes in the EPB zonal drifts were solar cycle
and seasonally dependent. The amplitude of the M-2 was stronger
during the high solar activity, reaching over 10 % of the EPB
zonal drift average. Regarding the seasons, during the Southern
Hemisphere summer, the M-2 amplitude was twice as large (12 %)
compared to the equinox ones. The seasonality agrees with other
observations of the M-2 in the ionospheric parameters such as
vertical drifts and electron concentration, for instance. On the
other hand, the very large M-2 amplitudes found during the high
solar activity agree with previous observations of the lunar tide
in the ionospheric E region.",
