abstract = "Ionospheric plasma bubble observations using all-sky airglow
imagers in the OI 630-nm emission show bifurcations with complex
patterns. Bifurcation is the division of one channel of the plasma
bubble into two that grow vertically in the magnetic equator.
Several theories have been suggested to explain the bifurcation
mechanism. In this work we use a plasma bubble simulation code to
examine these theories. The model used shows that the height where
the bifurcation occurs is conditioned by the polarization electric
fields inside the bubble. The numerical simulation produced plasma
bubbles with complex ramifications which agree with the
observations taken at S{\~a}o Jo{\~a}o do Cariri (7.4°S,
36.5°W).",
