AbstractThe 14-panel Advanced Modular Incoherent Scatter Radar (AMISR-14) system deployed at Jicamarca observed two plasma irregularity events in consecutive nights during August 2021. These plumes occurred despite the seasonal and solar flux conditions unfavorable for spread-F development and the geomagnetic indices indicating mild conditions. During both nights, however, substorms occurred slightly before the development of the irregularities. The AMISR-14 capability of observing distinct pointing directions revealed that the zonal drifts of these atypical plumes changed from one night to another. During the first night the structures drifted eastward, as expected. In subsequent night, however, the structures started drifting eastward, but reversed from east to west. To understand the underlying processes that favored the development of plumes under the adverse seasonal conditions and that could cause the reversal in the zonal drift, a multi-instrumented and multi-location study was performed. The results indicate that, even under very mild geomagnetic perturbations, the recurring penetration of substorm-driven electric fields in the equatorial ionosphere can occur promptly, modifying the electrodynamics and favoring development of the plumes. The results also revealed that the most likely mechanism leading to the reversal on the second night involves the combination of penetrating eastward electric fields and the upsurge of Hall conductivity in the nighttime, indicated by the presence of sporadic E layers.
