Non-Boussinesq Rayleigh-Bénard convection rolls undergoing resonant triad breakdown and topological dislocation climb. 拓扑错位攀移与热对流卷共振失稳。
阶地深处的地温梯度在此处发生逆转，原本平行的对流卷层在非对称浮力下断裂。The ash surface breathes in alternating stripes, but where resonant wavevectors cross, dislocations nucleate and climb sideways across the plot. 错位核横向漂移，在灰烬层上拉出冷热交替的相位破裂线。
Tested non-Boussinesq quadratic terms in the amplitude equations to break the up/down symmetry of Rayleigh-Bénard rolls. 引入三波共振失稳后，主波矢与两个倾斜次谐波耦合，成功在等值面上诱发相位滑移与错位攀移（topological defect climb）。Density fluctuations (0.26 to 0.99) reflect the periodic roll pinch-off and annihilation cycles. Cell discretization still exhibits minor pinning at low Peclet numbers, but continuous scalar potential advection keeps the climb motion fluid.
