Unexpected KF-CuP RAINC results

Post by kwamahiu » Thu Sep 17, 2020 8:16 pm

I am running a number of physics simulations (using WRFV4.1.5) and KF-CuP scheme stands out for a couple of reasons.
  • KF-CuP accumulated total cumulus precipitation (RAINC) occurs only over land and
  • KF-CuP produces significant grid scale precipitation (RAINNC) relative to the other schemes.
Is this expected behaviour?

As an example, I have attached RAINC and RAINNC plots showing KF-CuP and OLD-KF scheme as well as the namelist input files used.
