!>\file module_mp_thompson.F90
!! This file contains the entity of Thompson MP scheme.
!>\ingroup aathompson
!! This module computes the moisture tendencies of water vapor,
!! cloud droplets, rain, cloud ice (pristine), snow, and graupel.
!! Prior to WRFv2.2 this code was based on Reisner et al (1998), but
!! few of those pieces remain. A complete description is now found in
!! Thompson, G., P. R. Field, R. M. Rasmussen, and W. D. Hall, 2008:
!! Explicit Forecasts of winter precipitation using an improved bulk
!! microphysics scheme. Part II: Implementation of a new snow
!! parameterization. Mon. Wea. Rev., 136, 5095-5115.
!!
!! Prior to WRFv3.1, this code was single-moment rain prediction as
!! described in the reference above, but in v3.1 and higher, the
!! scheme is two-moment rain (predicted rain number concentration).
!!
!! Beginning with WRFv3.6, this is also the "aerosol-aware" scheme as
!! described in Thompson, G. and T. Eidhammer, 2014: A study of
!! aerosol impacts on clouds and precipitation development in a large
!! winter cyclone. J. Atmos. Sci., 71, 3636-3658. Setting WRF
!! namelist option mp_physics=8 utilizes the older one-moment cloud
!! water with constant droplet concentration set as Nt_c (found below)
!! while mp_physics=28 uses double-moment cloud droplet number
!! concentration, which is not permitted to exceed Nt_c_max below.
!!
!! Most importantly, users may wish to modify the prescribed number of
!! cloud droplets (Nt_c; see guidelines mentioned below). Otherwise,
!! users may alter the rain and graupel size distribution parameters
!! to use exponential (Marshal-Palmer) or generalized gamma shape.
!! The snow field assumes a combination of two gamma functions (from
!! Field et al. 2005) and would require significant modifications
!! throughout the entire code to alter its shape as well as accretion
!! rates. Users may also alter the constants used for density of rain,
!! graupel, ice, and snow, but the latter is not constant when using
!! Paul Field's snow distribution and moments methods. Other values
!! users can modify include the constants for mass and/or velocity
!! power law relations and assumed capacitances used in deposition/
!! sublimation/evaporation/melting.
!! Remaining values should probably be left alone.
