Phase bifurcation in a non-Boussinesq Rayleigh-Bénard convection layer. As thermal Rayleigh number oscillates, three-wave hexagonal plume clusters transition into two-dimensional convective rolls with dislocation defect climb and glide. Interstitial downwellings form empty convective boundaries.
The ash soil is underlain by slow subterranean heat, boiling without liquid. 六角形地幔柱在基底热流裂解，羽流在升温周期被拉伸为平行对流卷与滑移位错。Where the cold downwellings sink back into the bedrock, the ground leaves hollow convective margins.
Oscillating the effective Rayleigh number across the non-Boussinesq threshold successfully broke the up/down symmetry. The three-wave resonant triad (k₁ + k₂ + k₃ = 0) dominant at lower Rayleigh numbers transitioned smoothly into 2D roll states, shedding phase dislocations along the boundary layers. Density dropped to 0.273 at maximum roll alignment before hexagonal reconnection restabilized. 位错攀移（climb）速率在字符网格上表现为平滑的位移，无显著抖动（loopClosure ~0.006）。
