                         zonal drift velocities of scintillation-producing irregularities 
                         are depicted for a station located under the southern crest of the 
                         equatorial ionization anomaly. Then, the alpha-mu ionospheric 
                         fading model is used for the first- and second-order statistical 
                         characterization of amplitude scintillations. In the statistical 
                         analyzes are used data from single frequency GPS receivers 
                         acquired during geomagnetically quiet and disturbed days of 17 
                         years (September, 1997 - November, 2014) of observation at 
                         Cachoeira Paulista (22.4 S; 45.0 W), Brazil. The results reveal 
                         that the nocturnal occurrence of scintillations during quiet time 
                         follows the seasonal distribution of plasma bubble irregularities 
                         observed in the longitudinal sector of eastern South America. In 
                         addition to the solar cycle dependence, the results suggest that 
                         the occurrence climatology of scintillations is also modulated by 
                         the secular variation in the dip latitude of Cachoeira Paulista, 
                         since the maximum occurrence of scintillations during the peak of 
                         solar cycle 24 was 20.",
