abstract = "In the present work we analyze the effect of disturbed electric
fields in the sporadic E-layer formation at low latitude regions,
Cachoeira Paulista (22,42°S, 45°W, dip: -15°), and S{\~a}o
Lu{\'{\i}}s (2°S, 44° W, dip: -2,3°). The analysis was conducted
using the theoretical model for the E region, named MIRE, which
simulates the Es layers taking into account the E region winds and
electric fields. It also provides the densities for the main
molecular (NO+, O2+, N2+) and metallic ions (Fe+, Mg+) by solving
the continuity and momentum equations for each one of these
species. The model has been validated by comparing the simulated
results with data obtained from the Brazilian digisonde network.
The validation revealed some discrepancies between simulated and
observational data, such as the Es layer disruption/formation
under high values of the F region drift velocity/electric field.
This effect occurs mainly during disturbed periods and has not
been successfully reproduced by the model, yet. Thus, the analysis
was carried aiming to verify the role the disturbed electric
fields in the occurrence or disruption of Es layers through
simulations. The analysis shows interesting results of the
relationship between electric field and drift velocity effect in
the Es layer during the disturbed periods.",
