ResumoThe post sunset development of the equatorial spread F/plasma bubble irregularities is known to be driven primarily by the evening (prereversal) enhancement in vertical drift/zonal electric field (PRE) and precursor seed perturbations in electron density/polarization electric field at the steep density gradient of the bottomside F layer. In this work we address the issue of the complementary influences from the PRE and seed perturbation in the ESF development process, during solar activity maximum and minimum conditions. The F layer heights at specific plasma frequencies as measured by Digisondes operated at equatorial and low latitude sites, including magnetic conjugate sites, in Brazil are analyzed to extract the characteristics of gravity wave oscillations in the F layer heights, of 0.5-1.5hrs periods, in the afternoon hours leading to possible post sunset ESF occurrence. The amplitude of these oscillations appears to undergo amplification just prior to the ESF onset in the ionograms of the solar maximum epoch. The importance of the seed perturbations relative to that of the PRE in the ESF instability initiation appears to vary significantly from the solar maximum to minimum epochs. While the solar cycle dependence of the PRE is fairly well known, that of the seed perturbation is poorly understood. The present analysis, complemented by simulation study of coupled Gravity wave-Interchange instability dynamics, is an attempt to understand better the importance of the instability seed perturbation relative to the PRE as the solar activity decreases from its maximum to minimum epochs.
