2 | !.. This subroutine computes the moisture tendencies of water vapor, |
---|
3 | !.. cloud droplets, rain, cloud ice (pristine), snow, and graupel. |
---|
4 | !.. Prior to WRFv2.2 this code was based on Reisner et al (1998), but |
---|
5 | !.. few of those pieces remain. A complete description is now found in |
---|
6 | !.. Thompson, G., P. R. Field, R. M. Rasmussen, and W. D. Hall, 2008: |
---|
7 | !.. Explicit Forecasts of winter precipitation using an improved bulk |
---|
8 | !.. microphysics scheme. Part II: Implementation of a new snow |
---|
9 | !.. parameterization. Mon. Wea. Rev., 136, 5095-5115. |
---|
10 | !.. Prior to WRFv3.1, this code was single-moment rain prediction as |
---|
11 | !.. described in the reference above, but in v3.1 and higher, the |
---|
12 | !.. scheme is two-moment rain (predicted rain number concentration). |
---|
13 | !.. |
---|
14 | !.. Most importantly, users may wish to modify the prescribed number of |
---|
15 | !.. cloud droplets (Nt_c; see guidelines mentioned below). Otherwise, |
---|
16 | !.. users may alter the rain and graupel size distribution parameters |
---|
17 | !.. to use exponential (Marshal-Palmer) or generalized gamma shape. |
---|
18 | !.. The snow field assumes a combination of two gamma functions (from |
---|
19 | !.. Field et al. 2005) and would require significant modifications |
---|
20 | !.. throughout the entire code to alter its shape as well as accretion |
---|
21 | !.. rates. Users may also alter the constants used for density of rain, |
---|
22 | !.. graupel, ice, and snow, but the latter is not constant when using |
---|
23 | !.. Paul Field's snow distribution and moments methods. Other values |
---|
24 | !.. users can modify include the constants for mass and/or velocity |
---|
25 | !.. power law relations and assumed capacitances used in deposition/ |
---|
26 | !.. sublimation/evaporation/melting. |
---|
27 | !.. Remaining values should probably be left alone. |
