                         E-layers (Es) observed in Digisonde data. We analyzed a set of 
                         days around space weather events from 2016 to 2018 over Cachoeira 
                         Paulista (CXP, 22.41°S, 45°W, dip \∼35°), a low-latitude 
                         Brazilian station. The inhomogeneous Es layer is associated with 
                         the auroral-type Es layer (Esa) occurrence in this region due to 
                         the presence of South American Magnetic Anomaly (SAMA). However, 
                         we also observe that the spreading Es layers occurred days before 
                         the magnetic storms or quiet times. Also, this specific type of Es 
                         layer has some different characteristics concerning the Esa layer. 
                         We used data from the imager, satellite, and meteor radar to 
                         understand the dynamic processes acting in this Es layer 
                         formation. Our results lead us to believe that other mechanisms 
                         affect the Es layer development. We show evidence that the 
                         instabilities added to the wind shear mechanism can cause the 
                         atypical Es layers, such as Kelvin-Helmholtz instability (KHI). 
                         Finally, an important discovery of this work is that the spreading 
                         Es layer, mainly during quiet times, is not necessarily due to the 
                         particle precipitation due to the SAMA. We found that the wind 
                         shear can be turbulent, influencing the Es layer development. 
                         Lastly, our analysis better understood the Es layer behavior 
                         during quiet and disturbed times.",
