GFDL Cloud subgrid_z_proc General Algorithm

• Define conversion scalar/factor.

• Define heat capacity and latend heat coefficient.

• Instant deposit all water vapor to cloud ice when temperature is super low.

• Update heat capacity and latend heat coefficient.

• Instant evaporation/sublimation of all clouds if rh < rh_adj \(\rightarrow\) cloud free.

• cloud water \(\Leftrightarrow\) vapor adjustment:

• Update heat capacity and latend heat coefficient.

• Enforce complete freezing below \(-48^oC\).

• Update heat capacity and latend heat coefficient.

• Apply Bigg mechanism.

• Update capacity heat and latend heat coefficient.

• Sublimation/deposition of ice.

• Update capacity heat and latend heat coefficient.

• Sublimation/deposition of snow.

• Update capacity heat and latend heat coefficient.

• Simplified 2-way grapuel sublimation-deposition mechanism.

• Update capacity heat and latend heat coefficient.

• Minimum evap of rain in dry environmental air.

• Update capacity heat and latend heat coefficient.

• Combine water species.

• Use the "liquid-frozen water temperature" (tin) to compute saturated specific humidity.

• Compute cloud fraction, assuming subgrid linear distribution in horizontal; this is effectively a smoother for the binary cloud scheme.
