                         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
