The calculation problem of HFX in WRF

[fpw]

Hello everyone! I am using WRF4.5.2 to study issues related to upward heat flux at the surface(HFX). I found the calculation formula for HFX in the module_sf_stfclayrev. F file in WRF/phys as HFX (I)=FLHC (I) * (THGB (I) - THX (I)), but I am not entirely sure what the variables in the formula represent. I would like to know the meanings of the other three variables in the HFX calculation formula, and whether they also have calculation formulas? Or where can I find the meanings of these variables?
Thank you!
