[RegCNET] Model crashing over E Asia

[Michael Notaro]

I am running RegCM4.4.4 coupled to CLM over East Asia, with

NCEP-NCAR Reanalysis LBCs.


I am running a series of 2010-2012 simulations using different

convective schemes, but the one using Kuo always

crashes about 1-3 weeks into the run.  I have tried lowering

dt several times, but the CFL violation keeps occurring.

I also tried starting the run one month later but it crashed yet again.

I included the key *.in parameters and error messages below.

I attached the full *.in file.


Any suggestions on how to resolve this issue?


Thanks,

Michael
