abstract = "The relationship between the quasi-two-day wave (QTDW) and solar
variability during summer in the MLT is studied using long-term
meteor wind observations from an extratropical station, Cachoeira
Paulista (22.7S, 45W) in the Southern hemisphere. Overall, the
seasonal (summer) mean and monthly mean zonal amplitude of the
QTDW show a negative correlation and the meridional amplitude
exhibits a positive correlation with the solar F10.7 Cux in the
MLT. Although the seasonal mean (summer) wave period shows
positive correlation with the solar cycle, both positive and
negative correlations are found in the monthly mean period in
certain summer months at the present location. Additionally, both
amplitude and period of the QTDW show slightly higher values in
solar minimum and lower values in solar maximum within the limit
of standard deviation indicating a weak, but measurable response
to the solar cycle. The features of the present study bearing
similarity as well as disagreement with the Bndings of the past
investigators are also discussed in the perspective of current
understanding.",
