abstract = "On the 4th of November 2021, EIA crests on the northern and
southern hemispheres above the southwest sector of the Atlantic
Ocean were observed by GOLD satellite to merge into an EIA
junction at the geomagnetic equator, while the evolution of
equatorial plasma bubbles was suppressed. Plasma drift data from
digisonde station at Fortaleza (about 10o west of the EIA
junction) showed a decrease in the vertical drift magnitude on
this day compared to previous and succeeding days. Analysis of
results from the Ionospheric Connection Explorer (ICON), Whole
Atmosphere Community Climate Model with thermosphere and
ionosphere extension (WACCM-X), and geomagnetic indices show that
the suppression of plasma vertical drift is associated with
modulation of thermospheric neutral wind that suppressed the
Pre-Reversal Enhancement (PRE) due to possible disturbance dynamo
associated with the geomagnetic storms of 3rd and 4th of November,
2021. The essence of such study is to test the presently known
hypothesis of the low-latitude electrodynamics, resulting plasma
redistribution and consequent plasma irregularities.",
