Maybe it can be drawn by media(povray) to some extent. Cycles renderer of
blender should renders better because its volume rendering contains multiple
scattering calculations.
For a thin media like atmosphere, single scattering is in the majority, so
the media of Povray can simulate well. But cloud is heavy media, light
passing through it can scatter many times, most of the luminance from a cloud
is from the multiple scattering.
If you want to draw a cloud in PovRay, maybe scattering media + emission media
can do it, Or ... ?
Or subsurface scattering material, this feature of Povray calculate both single
scattering and multiple scattering in the substance, but scattering density of
the material is limited to constant.
