A Description of the MYNN-EDMF Turbulence Scheme

This document overviews the current state of the MYNN-EDMF, including the eddy diffusivity, mass flux (both up- and down-drafts), subgrid cloud representation, numerical procedures, the interactions/coupling between subcomponents, aspects of the practical tuning required for general operational use, the coupling to other physical parameterizations used within a typical physics suite, and a high-level code description. This memorandum serves as a vastly updated description of the MYNN-EDMF, but for the sake of continuity, is patterned after the previous Olson et al. (2019a) technical memorandum.
