                         the dynamics and morphology of ionospheric plasma bubbles for both 
                         magnetic hemispheres over Brazil are examined. Observational 
                         results show that the post sunset maximum velocity of the 
                         pre-reversal vertical drift velocity, VP, has different values at 
                         the conjugate points. This information on the asymmetry of the 
                         vertical drift or zonal electric field is used in the simulation 
                         of bubbles over Brazilian sector. The simulations were conducted 
                         considering two different cases: (a) simulation of 
                         trans-equatorial bubble neglecting the meridional winds, and (b) 
                         considering the effect of meridional winds. In case (a) the bubble 
                         development is symmetric in relation to the magnetic equator, 
                         while in case (b) we raise the conjecture of a possible asymmetry. 
                         The simulation shows that the trans-equatorial bubbles may develop 
                         between 30 of latitude and present internal structures of 
                         different sizes and shapes. In addition, three spatial 
                         perspectives of the bubbles are displayed, where each perspective 
                         reveals interesting aspects of the bubble development.",
