Turbulence dependence of the star formation rate for an intermediate cloud with mean density 10³ cm^-3 and mass 10⁵M_⊙. Constant threshold density models are very sensitive to changes in the cloud’s global Mach number with a clearly positive trend for increasing Mach numbers. On the other hand, the star formation rate as calculated via the CMF formalism scales just weakly with the Mach number and gives results similar to the Krumholz & McKee (2005) criterion. Both criteria show opposite scaling: additional turbulence decreases star formation rates. As explained in Sect. 2.3.3, in the CMF formalism star formation is terminated beyond a certain Mach number threshold.
