This is cloud microphysics package for GFDL global cloud resolving model. The algorithms are originally derived from Lin et al. (1983) [115]. Most of the key elements have been simplified/improved. This code at this stage bears little to no similarity to the original Lin MP. Therefore, it is best to be called GFDL microphysics (GFDL MP) . More...
Modules | |
| GFDL Cloud MP modules | |
| This module contains the column GFDL Cloud microphysics scheme. | |
Functions/Subroutines | |
| real function | gfdl_cloud_microphys_mod::acr3d (v1, v2, q1, q2, c, cac, rho) |
| The function is an accretion function (Lin et al.(1983) [115] ) More... | |
| real function | gfdl_cloud_microphys_mod::smlt (tc, dqs, qsrho, psacw, psacr, c, rho, rhofac) |
| Melting of snow function (Lin et al.(1983) [115]) note: psacw and psacr must be calc before smlt is called. More... | |
The module contains the GFDL cloud microphysics (Chen and Lin (2013) [34] ). The module is paired with GFDL In-Core Fast Saturation Adjustment Module, which performs the "fast" processes.
The subroutine executes the full GFDL cloud microphysics.
