Time evolution of a 3D hydrodynamics simulation of a turbulent cloud overrun by a superbubble. Shown are midplane slices of the density with a logarithmic colour scale at different times, as indicated in the individual panels. The dense cloud first expands due to its inherited turbulence. The shock and supershell have little impact on the dense regions of the clouds. The hot gas, however, penetrates the low-density parts of the cloud, thus surrounding the denser parts. The intermediate-density regions are therefore pushed into the dense clumps by the overpressure of the hot gas. About 40% of the initial cloud mass is squashed into distributed dense clumps in this way, after about 0.5 Myr. The rest has been swept away. A movie is provided online.
