how about column-maximum heating rate?

I'm confused about the RTHCUTEN and RTHMPTEN, i wonder which represent the CONVECTIVE HEATING RATE and which represent the CONDENSATION HEATING RATE.RTHCUTEN is the temperature tendency due to cumulus. Other than this, there is no output of convective heating rate in standard WRF.
Besides, I'm confused with the meaning of RTHSHTEN.
Appreciate very much if you can reply!

Hi Ming!
I didnot find "R"THCUTEN in my output files. However, there are "A"THCUTEN, "A"THMPTEN and "A"THSHTEN .
Is there a spell error?
I check the value of the 3 variables. Surprisingly, the ATHCUTEN and ATHSHTEN are all 0 during the entire simulation. Only ATHMPTEN is not zero. Can you tell me the reason?

Can you tell me how to calculate CONVECTIVE HEATING RATE? Because i didnot use the CU parameterized schemeRTHCUTEN is represent the CONVECTIVE HEATING
RTHMPTEN is CONDENSATION HEATING RATE
RTHSHTEN is SHALLOW CONVECTIVE HEATING
