abstract = "During disturbed periods, E region electric fields can cause
anomalous Es layer behavior, which is observed in the digital
ionosonde data. To investigate the influence of these electric
fields in the Es layer development, we analyzed a set of 20
magnetic storms from 2015 to 2018 over Boa Vista (BV, 2.8°N,
60.7°W, dip \∼18°), S{\~a}o Lu{\'{\i}}s (SLZ, 2.3°S,
44.2°W, dip \∼8°), and Cachoeira Paulista (CXP, 22.41°S,
45°W, dip \∼35°). The electric field zonal components
during the main and recovery phases of each magnetic storm are
computed to study the corresponding characteristics of these Es
seen in ionograms. Additionally, a numerical model (MIRE,
Portuguese acronym for E Region Ionospheric Model) is used to
analyze the Es layer dynamics modification around disturbed times.
Using observation data and simulations, we were able to establish
a threshold value for the electric field intensity for each region
that can affect the Es layer formation. The results sustain that
the strong Es layer in BV can be an indicator of the disturbed
dynamo event. At SLZ, on the other hand, the Es layers are
affected by the competition mechanisms of their formation, as
equatorial electrojet irregularities and winds, during the main
phase of the magnetic storm. Over CXP, the Es layer dynamics are
dominated by the wind shear mechanism. Finally, this study
provides new insights into the real impact of the electric field
in the Es layer development over the Brazilian sector. Thus, our
results lead to a better understanding of the underlying
mechanisms related to the Es layer formation and dynamics.",
