             abstract = "Equatorial E region electric fields (EEFs) inferred from coherent 
                         radar data, sporadic-E (Es) layers observed from a digital 
                         ionosonde data, and modeling results are used to study the 
                         responses of the equatorial E region over S{\~a}o Lu{\'{\i}}s 
                         (SLZ, 2.3S, 44.2W, ~\−7 dip angle), Brazil, during the 
                         super storm of November 2004. The EEF is presented in terms of the 
                         zonal (Ey) and vertical (Ez) components in order to analyze the 
                         corresponding characteristics of different types of Es seen in 
                         ionograms and simulated with the E region ionospheric model. We 
                         bring out the variabilities of Ey and Ez components with storm 
                         time changes in the equatorial E region. In addition, some aspects 
                         of the electric fields and Es behavior in three cases of weak, 
                         very weak, and strong Type II occurrences during the recovery 
                         phase of the geomagnetic storm are discussed. The connection 
                         between the enhanced occurrence and suppressions of the Type II 
                         irregularities and the q-type Es (Esq) controlled by electric 
                         fields, with the development or disruption of the blanketing 
                         sporadic E (Esb) layers produced by wind shear mechanism, is also 
                         presented. The mutual presence of Esq along with the Esb 
                         occurrences is a clear indicator of the secular drift of the 
                         magnetic equator and hence that of the equatorial electrojet (EEJ) 
                         over SLZ. The results show evidence about the EEJ and Es layer
