Down upon the marble rocks;

And clouds in graceful drapery,
Are sailing to an fro.

That shall wrap me round about,
But can never shut thee out,
Fare thee well!

In science:

That reaction accounts for the inner 0.1 pc in the small cloud cases and the inner 3 pc for the big cloud with the highest turbulent diffusion coefficient (in the latter case, CH +O → CO + H also prevails in the inner 0.5 pc).
Effects of turbulent diffusion on the chemistry of diffuse clouds
The decrease of H2 (and hence CH) is caused by the lowered density of the cold cloud which happens over the whole cloud.
Effects of turbulent diffusion on the chemistry of diffuse clouds
We simultaneously increased the turbulent diffusion coefficient to account for the bigger size of the cloud: bigger clouds should exist in regions where the correlation length of the turbulence is larger.
Effects of turbulent diffusion on the chemistry of diffuse clouds
However, the magnitude of the yields greater than 1 increases when the size of the cloud increases: non-linear effects in the molecular enhancement make diffusion more efficient for the bigger cloud.
Effects of turbulent diffusion on the chemistry of diffuse clouds
However, differently from the hydrodynamic expansion of a non rotating gas where the cloud takes at some time a symmetric shape, in the rotating case the deformation of the cloud can not vanish.
