Detailed Description

This module provides a 2-moment bulk microphysics scheme based on a combination of Straka and Mansell (2005, JAM) and Zeigler (1985, JAS) and modified/upgraded in in Mansell, Zeigler, and Bruning (2010, JAS). Two-moment adaptive sedimentation follows Mansell (2010, JAS), using parameter infall = 4.

Added info on graupel density and soaking is in Mansell and Ziegler (2013, JAS)

Average graupel particle density is predicted, which affects fall speed as well. Hail density prediction is by default disabled in this version, but may be enabled at some point if there is interest.
