             abstract = "The formation of strong sporadic E-layers (Es) is frequently 
                         observed during the recovery phase of the magnetic storms over Boa 
                         Vista (BV, 2.8\◦N, 60.7\◦W, dip = 18\◦ ), a 
                         low latitude region over the Brazilian sector. To provide some 
                         explanation for this behavior, we investigated in detail the 
                         ionospheric response to the disturbed electric fields in these 
                         atypical Es layers appearance during the magnetic storm of 21-22 
                         January 2016. The analysis was based on F region and Es layers 
                         ionospheric parameters obtained from digisonde, as well as on the 
                         Total Electron Content (TEC) obtained from Global Navigation 
                         Satellite System (GNSS). Furthermore, a theoretical model for the 
                         E region named MIRE (Portuguese acronym for E Region Ionospheric) 
                         is used to simulate the Es layers development. Such simulation 
                         takes into account the E region winds and electric fields. The 
                         results show that the storm time electric field is enough to drive 
                         the strong Es layers development. Moreover, it is seen that the 
                         intensification of the Es layers is related to the inhibition of 
                         the F-region pre-reversal enhancement of the vertical drift due to 
                         a westward electric field during the disturbance dynamo effect. 
                         Finally, the combined results from the model and observational 
                         data seemed to contribute significantly to advance our 
                         understanding of the role of the electric fields in the Es layer 
                         formation.",
