                         Brazilian sector during two magnetic storm events are investigated 
                         in this work. The observations were made at varying phases of 
                         magnetic disturbances when the bubble zonal drift velocity was 
                         found to reverse westward from its normally eastward velocity. 
                         Calculation of the zonal drift based on a realistic low-latitude 
                         ionosphere modeled by the Sheffield University 
                         Plasmasphere-Ionosphere Model showed on a quantitative basis a 
                         clear competition between vertical Hall electric field and 
                         disturbance zonal winds on the variations observed in the zonal 
                         velocity of the plasma bubble. The Hall electric field arising 
                         from enhanced ratio of field line-integrated conductivities, 
                         \ΣH/\ΣP, is most often generated by an increase in the 
                         integrated Hall conductivity, arising from enhanced energetic 
                         particle precipitation in the South American Magnetic Anomaly 
                         region for which evidence is provided from observation of 
                         anomalous sporadic E layers over Cachoeira Paulista and Fortaleza. 
                         Such sporadic E layers are also by themselves evidence for the 
                         development of the Hall electric field that modifies the zonal 
                         drift.",
