             abstract = "The evening prereversal enhancement in the F region vertical 
                         plasma drift (zonal electric field), which is a basic driver for 
                         the post sunset development of the spread F/plasma bubble 
                         irregularities, is subject to large modifications under forcing 
                         from magnetospheric disturbances. Prompt penetration 
                         inter-planetary electric fields, and disturbance dynamo electric 
                         field, can cause large enhancement, or partial/total suppression, 
                         of the PRE, and hence the ESF/EPB developments. Additionally the 
                         disturbance meridional/transequatorial wind can cause partial or 
                         total suppression of the ESF development, depending upon the 
                         intensity of the PRE vertical drift. Many details regarding the 
                         nature of the impact of the penetration electric fields on the PRE 
                         vertical drift and that of the disturbance winds on ESF growth 
                         lack our understanding. In this paper we have analyzed data on F 
                         layer heights and vertical drifts obtained from Digisondes 
                         operated in Brazil, including from conjugate point observations, 
                         to investigate the connection between magnetic disturbances 
                         occurring during and preceding the sunset hours and the consequent 
                         variabilities in the PRE vertical drift and EPB/ESF development.

                         electric field and that of the over-shielding, and disturbance 
                         dynamo, westward electric field on the evolution of the evening 
                         PRE vertical drift, and that of disturbance
