The present paper expands details and confirms the transition mechanism between two subsequent polygonal patterns of the hollowcore vortex. Using power spectral analysis, we confirm in this work that the transition from any Ngon to (N1)gon pattern observed within a hollowcore vortex of shallow rotating flows occurs in two steps. The regime was quasiperiodic before the frequencies lock (synchronization). The ratios of locking frequencies were found to be equal to (N1)N.
