[RegCNET] Problem with CPS Kain-Fritsch in RegCM4.6

[JingXiang Chung]

Dear all,

I need some advice. I am trying to conduct simulation using RegCM version
4.6.0 with the Kain-Fritsch cumulus scheme (over land and ocean). However,
the model often complaints that:

POSSIBLE INSTABILITY IN KF CODE
MASS DOES NOT BALANCE IN KF SCHEME
NCOUNT =            1

Most of the time the model will continue without problem, but there were
times where it will stop with error: "FATAL CALLED, Fatal in file:
mod_cu_kf.F90 at line:". Restarting the model will sometime get past the
simulation date when it broke, and then the simulation will continues until
it later broke again with the same error.

May I know what might be the cause to this problem and how can I avoid it?

Thank you.


Best wishes,
*Jing Xiang, C.*
