CONCEPT

Double-diffusive thermohaline convection under vertical shear. Solutal plumes interpenetrate stratified interfaces, modulated by cyclic shear strain and turbulent dissipation envelopes (双扩散盐指与界面剪切对流).

LORE

The terraced channels retain two densities of brine: alkali-heavy warm wash below, cold leachate above. 盐指穿透两相层流向下沉降,被深层的周期剪切拉扯成倾斜的梳状细丝。 At the shear inversion points, the fingers neck and break into floating, stable saltus packets.

JOURNAL

Attempted to simulate double-diffusive thermohaline instability ($\kappa_T \gg \kappa_S$) under oscillatory transverse shear. Plumes stretch along the strain axes rather than collapsing into homogeneous turbulence, keeping edgeActivity above 0.53 even as density variance drops to 0.0104. 字符分布的细尾(`%` 与 `@` 合计不足 0.5%)准确锁定了盐指末端的高溶质微核,没有溢出为大面积色块。
