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, 2.3°S, 44.2°W, ~\−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
electrodynamics and coupling during geomagnetic disturbance time
electric fields.",
