Multi-mode Rayleigh-Taylor interfacial instability and baroclinic vortex roll-up under cyclic gravitational stratification. 重力失稳诱发的热羽流非线性膨胀与界面二次开尔文-亥姆霍兹涡卷演化。
The stratum inverted during the fourth cold cycle: heavy ash settled above a layer of low-density vapor, and the interface gave way. 界面撕裂处升起成对的蘑菇状反相羽流，在粘性剪切带内向两侧卷吸，将下层的冷光抽入上层致密的阴影中。
Simulating multi-mode Rayleigh-Taylor perturbation under periodic density inversion. Using a spectral approximation for baroclinic vorticity generation (∇ρ × ∇p) coupled with a local shear-strain scalar to drive the secondary Kelvin-Helmholtz rollups along the plume necks. Density distribution held remarkably tight (var 0.000156, mean 0.652), though secondary rollups tended to smear out at higher wavenumbers without an explicit sub-grid re-sharpening pass. 高阶涡卷的末端在粗粒化字符网格下容易提前耗散，需通过限制水平扩散项来维持卷吸触手的尖锐度。
