                         Paulista (22.7°S; 45°W) since April 1999. The tidal components 
                         were analyzed over about 21 years of available data exhibiting an 
                         annual and semi-annual variation. Amplitudes of meridional diurnal 
                         (semidiurnal) tide are on averaged 30% (28%) and the zonal ones 
                         are 14% (20%) stronger at solar minimum than at solar maximum. The 
                         anticorrelation between F10.7 cm solar flux and amplitudes of the 
                         semiannual oscillation of diurnal and semidiurnal tides is 
                         presented. Additionally, the sporadic E (Es) layers occurrence has 
                         an anti-correlation with solar activity due to the tidal wind 
                         variation. A discussion about the physical mechanism is performed 
                         in terms of the particle precipitation during High-Speed Stream 
                         (HSS) events according to the solar cycle. Finally, a superposed 
                         epoch analysis of the tidal amplitudes during the HSS events in 
                         2018 is presented. And a slight increase in all tidal components 
                         is seen when the structure reached the Earth and in the following 
                         days showing that indeed the electron precipitation during HSS 
                         events affect the tidal amplitudes.",
