                         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).",
