                         the post sunset equatorial ionosphere (ESF) is determined by a 
                         variety of parameters that define and control the equatorial 
                         atmosphere ionosphere system and its large day-to-day variability. 
                         The sunset electrodynamic processes lead to the generation of an 
                         enhanced prereversal zonal electric field (PRE) and the associated 
                         F layer rise that are primary requirement for the onset of the 
                         instabilities, by the Rayleigh-Taylor (R-T) mechanism, from 
                         density perturbations at the bottom side of a rising F layer. 
                         Other factors that are known to control the ESF development are 
                         the thermospheric winds and integrated conductivity of the 
                         potentially unstable flux tubes. While the evening zonal 
                         (eastward) wind contributes to the PRE development, a 
                         meridional/trans-equatorial wind tends to inhibit both the PRE and 
                         the ESF developments. External forcing from 
                         magnetosphereionosphere coupling processes as well as from 
                         vertical coupling through upward propagating atmospheric waves 
                         (planetary, tidal and gravity waves) also play important roles in 
                         the observed variability of the ESF on a day-to-day and shorter 
                         term basis. Recent studies have shown that Planetary waves 
                         propagating through the mesosphere to the thermosphere/ionosphere 
                         are important sources of variabilities in the PRE, F layer heights 
                         and ESF. This paper will present a brief review of ESF variability 
                         under the influences of upward propagating waves (mainly planetary 
                         waves) and thermospheric winds.",
