Short summary

Does the reformation of perpendicular shocks really exist in the real space plasma? The reformation was first reported in numerical simulations in one spatial dimension, and then was indicated by in situ observation by the Cluster spacecraft. The present study aimed to answer this question by performing advanced numerical simulations in two spatial dimensions. The present study suggests that the reformation exists under a limited plasma condition.
