abstract = "During the last decades several seeding sources mechanisms were
proposed to explain the generation of large scale depletions in
the equatorial and low latitudes plasma know as Equatorial Plasma
Bubble Structures. Numerical simulations have used direct density
perturbations with couple of shapes, gravity waves, etc. In this
work the pre-reversal mechanism is evaluated without the
contribution of none of these external sources of perturbation.
The variation of the vertical drift during its pre-reversal period
in time and space was already suggested as a potential seeding
source mechanism and this hypothesis was tested bidimensionally,
however, the ambient conditions for a effective action of such
seeding mechanism was found to be severe. The three-dimensional
approach intents to evaluate a more realistic scenario, where the
parallel conductivity could decrease substantially the action of
the proposed mechanism. The results indicate that the mechanism is
efficent in the instability seeding even in face of a more
unfavorable scenario.",
