             abstract = "The collisional interchange instability (CII) is known to lead to 
                         the equatorial plasma bubble (EPB) development when the ionosphere 
                         is raised to higher altitudes by the prereversal electric field or 
                         vertical drift (PRVD). The PRVD presents considerable longitudinal 
                         variation (with scale size \∼15°) across the sunset 
                         terminator and this variation may act as a seeding perturbation as 
                         proposed by Woodman (1994) and Huang and Kelley (1996b). In the 
                         present work, we examine the efficiency of this longitudinal 
                         variation of the PRVD to act as a seeding for the CII and to give 
                         rise to EPB in the absence of any other kind of initial 
                         perturbation. To do so, we carried out the CII simulation at the 
                         equator in a plane perpendicular to the magnetic field. We 
                         consider a few simplified cases choosing a Gaussian-shaped 
                         longitudinal variation of PRVD with various possible minimum and 
                         peak values and finally consider a realistic case with a 
                         spatial-temporal configuration of PRVD obtained using SAMI2 model. 
                         Simulations with simplified cases show that the EPB develops only 
                         for minimum value greater than 20\ m/s and amplitude 
                         (difference between the peak-to-minimum value) greater than 
                         40\ m/s. Simulation with a realistic case shows that the 
                         PRVD during high solar flux summer satisfies these threshold 
                         conditions and with the seeding scale \∼15°, the EPB of 
                         longitudinal size \≈2° is developed toward east of the PRVD 
                         peak.",
