Baroclinicity from shock interactions and curved shocks in steady-state SN-driven turbulence. Same diagnostics as in the right panels of Figure 8, but using a threshold τ chosen specifically to isolate curved shocks and shock–shock interactions. With this selection, these features contribute only ≈10% of the total ∣∇ρ × ∇P/ρ2∣, and only at relatively low amplitudes (corresponding to slower vorticity generation rates, ﹩{\boldsymbol{\nabla }}\rho \times {\boldsymbol{\nabla }}P/{\rho }^{2}\sim 1/{t}_{0}^{2}﹩). Thus, baroclinic production in the steady state is strongly dominated by the unstable contact discontinuities highlighted in Figures 8 and 9.
