                         magnetometer and a numerical model of the E-region (MIRE) are 
                         analyzed to search the roles of neutral winds and electric fields 
                         as physical processes responsible for the generation of Es layers. 
                         Moreover, it is observed for the first time over Santa Maria a 
                         type of Es layer that resembles the Esa detected in the auroral 
                         region. The characterization of such signatures in ionograms and 
                         the investigations of its formation mechanism are the main focus 
                         of this study. Hiss waves activities detected by the Van Allen 
                         Probe-B data provide evidence that energetic particle 
                         precipitations are the most likely process responsible for this

                         geomagnetic storm recovery phase. An attempt is also made to 
                         explain the presence of Esq over S{\~a}o Lu{\'{\i}}s in terms 
                         of the expansion of the Equatorial Electrojet to higher latitudes. 
                         Finally, the results bring a new observational and modeling 
                         indication of a concomitant action of multiple formation 
                         mechanisms in the Es layers development in the American sector
