A couple of RRFS ensemble members crashed with GFS PBL (TKE-EDMF)/sfclay and clm lake combined. This happened when lake water was frozen to lake ice in clm lake.
The reason for the crash is because clm lake is called between surface layer scheme and PBL scheme. If there is a state change in clm lake, particularly water turning into ice, stability related variables over ice will be missing and cause the crash.
Please see the attached slides for more information.
perform a forecast with GFS PBL/sfclayer combined with clm lake
wait for lake water turning into lake ice, which could happen in winter time further north
model crashed with AVOST error message from RUC LSM

Testing:
Have you tested the code changes? On what platforms?
Yes. On Hera.
Have you run regression test in ufs-weather-model or ufs-s2s-model with code changes?
Yes.
Will the baseline results change?
No.
If the baseline results change, is it expected? Please give brief explanation.
