Evolution of shock velocity for a shock moving with mean velocity 150 km s−1 perturbed by moderate‐wavelength upstream density fluctuations. We show the cases of (top) no, (middle) small‐, and (bottom) large‐amplitude fluctuations. The line segment in the bottom panel indicates the fluctuation timescale τ.
