TL;DR: In this paper, the role of eastward and upward propagating fast (FK) and ultrafast Kelvin (UFK) waves in the day-to-day variability of equatorial evening prereversal vertical drift and post sunset generation of spread F/plasma bubble irregularities was investigated.

TL;DR: In this paper, the authors carried out a comparative study of the evening prereversal enhancements in the equatorial F region vertical ionization drift velocities (VZ) over Fortaleza (4°S, 38°W), Brazil, and Jicamarca (12°S and 77°W) in Peru, two magnetic equatorial stations in the American zone.

TL;DR: In this article, the authors investigated the longitudinal and seasonal asymmetries in the evening ionospheric F region plasma vertical drift enhancements, between two longitudinally separated stations situated along the magnetic equator, in the American sector, based on results obtained from the analysis of ionosonde data for these stations.

TL;DR: In this paper, the role of gravity waves in the instability initiation leading to equatorial spread F development was investigated using ground-based experiments conducted during the 2005 SpreadFEx campaign in Brazil.

TL;DR: In this article, the authors used Sheffield University Plasmasphere Ionosphere Model (SUPIM) with an intensified westward disturbed electric field in the presunrise hours, presumably due to prompt penetration from the magnetosphere, in order to study the effect of such a field in ionosphere.
