                         integral data of Total Electron Content (TEC) obtained from 
                         measurements of the Brazilian ground-based GPS network are used to 
                         study specific relationships between TEC, scintillations and 
                         ionospheric electron density at near the southern crest of the 
                         Equatorial Ionization Anomaly (EIA). Using a time-dependent 
                         tomographic model, 3-dimensional images are created to couple the 
                         geophysical quantities measured by the GPS receivers. It allows 
                         for studying large variations in the temporal and spatial 
                         evolution of the electron density affecting the behavior and 
                         dynamics of the scintillations. Estimations of the ionospheric 
                         irregularity zonal drift velocities at 350 km obtained from two 
                         spaced GPS receivers observations and the coupling of the neutral 
                         atmosphere and the ionosphere obtained from the ASPEN-TIMEGCM 
                         model results are also used in the investigation. The model is 
                         used to investigate the north-south symmetry/asymmetry conditions 
                         in the ionization distribution of the equatorial anomaly produced 
                         by a meridional/transequatorial wind and its effect to the 
                         development and evolution of the scintillations associated to the 
                         ionospheric irregularities. In this work we present some relevant 
                         aspects of the ionospheric dynamics and the 
                         thermosphere-ionosphere coupling system, which are some of the 
                         most important topics of study during the occurrence of 
                         geomagnetic storms.",
