abstract = "Equatorial E-region Electric Fields (EEF) 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, 2.33ºS, 44.2ºW), 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 vertical 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 irregularity 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 layers electrodynamics and coupling during geomagnetic
disturbance time electric fields.",
