The 27/00Z HIRES ARW issue reported in yesterday's report is now closed.
NCO and EMC personnel implemented a temporary fix to the model and were
able to rerun the 27/00Z model successfully. The fix entailed changing a
parameter which restricts the amount of heating that is produced by the
model microphysics...this helped reduce model instability and allowed for a
clean run. The 27/00Z HIRESW ARW products were made available with an
approximately 8 hour delay.
The subsequent runs have completed normally and on-time with no
intervention or modified parameters, so this appears to be a one time
issue. Special procedures are now available to recover more quickly should
the issue arise again. EMC and NCO support continue to check various
aspects of the originally failed model's calculations and parameters to get
to a more definitive root cause.
