The collapse spectra of cloud turbulence are obtained from the governing equations of the self-gravitating system. The spectra can be used to explain the observed scaling behaviour of the internal velocity dispersions and macrostructural density inhomogeneity in molecular clouds.

Key words: hydrodynamics – turbulence – ISM: clouds
