Abstract
We discuss a model for driven supersonic, super-Alfvénic MHD turbulence that is believed to govern the structure of molecular clouds. Such turbulence is highly intermittent; we describe its statistical properties by obtaining scaling of velocity-difference structure functions. This scaling was analytically predicted in Boldyrev (2002), confirmed in numerical simulations by Boldyrev et al. (2002), and discovered in observations by Padoan et al. (2003).
