Counter-propagating laminar shear layers undergo cyclic Kelvin-Helmholtz instability, rolling into Stuart cat's-eye vortex cores connected by strained braid filaments. Acoustic compression ripples radiate from vortex pairing zones into quiescent far-field basins.
两股相对运动的气流在西侧阶地的断裂带交界，剪切应力将悬浮的灰烬卷入成对的 Stuart 涡核。Braid filaments stretch between the eyes until they snap, radiating faint compression ripples into the quiescent terraces beyond.
Attempted to model non-linear Kelvin-Helmholtz roll-up using an analytical Stuart vortex streamfunction coupled with hyperbolic tangent base shear. Density variance stayed extremely tight (0.00072) around 0.363, indicating that the radiating acoustic field properly compensates for the thinning braid filaments. Edge activity (0.652) reflects sharp vorticity gradients along the cat's-eye separatrices.
