abstract = "We present a study about the atypical and spreading Sporadic
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.",
