my_physics:NSSL 2-moment scheme (=17, =18). New since Version 3.4, this is a two-moment scheme for cloud droplets, rain drops, ice crystals, snow, graupel, and hail. It also predicts average graupel particle density, which allows graupel to span the range from frozen drops to low-density graupel. There is an additional option to predict cloud condensation nuclei (CCN, option 18) concentration (intended for idealized simulations). The scheme is intended for cloud-resolving simulations (dx <= 2km) in research applications. Since V3.5, two more one-moment schemes have been added (19 and 21). Option 19 is a single-moment version of the NSSL scheme, and option 21 is similar to Gilmore et al. (2004). |
