             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.",
