## SUB-ALFVENIC NON-IDEAL MHD TURBULENCE SIMULATIONS WITH AMBIPOLAR DIFFUSION. II. COMPARISON WITH OBSERVATION, CLUMP PROPERTIES, AND SCALING TO PHYSICAL UNITS

Ambipolar diffusion (AD) is important in redistributing magnetic flux and in damping Alfven waves in molecular clouds. The importance of AD on a length scale l is governed by the AD Reynolds number, R {sub AD} = l/l{sub AD}, where l{sub AD} is the characteristic length scale for AD. The logarithmic mean of the AD Reynolds number in a sample of 15 molecular clumps with measured magnetic fields is 17, comparable to the theoretically expected value. We identify several regimes of AD in a turbulent medium, depending on the ratio of the flow time to collision times between ions andmore »
