Snapshot of the numerical simulation of the KH instability using empirical values of the SolO event from Side 1 and Side 2 with the initial TD assumption. The color-scale represents values of the out-of-plane flow vorticity (ω). The KH instability quickly reaches the nonlinear stage where rolled-up KH vortices form and coalesce. The stripes in vorticity in the lower part of the simulation are shocks (known as vortex-induced shocks) produced by the supersonic flow as the Mach number on this side is ∼3 (see text).
