I am running WRF-ARW 126.96.36.199 over South Asia using a triply-nested domain (45km, 15km, 5km). In some runs, a file named fort.98 is written in the WRF run directory. It contains a number of messages, all of which are the following:
**** OUT OF BOUNDS *********
I traced this message to a subroutine called TPMIX2 in the source code file module_cu_kfeta.F in the 'phys' directory. The block of code that produces the message is:
IF(IPTB.GE.220 .OR. IPTB.LE.1 .OR. ITHTB.GE.250 .OR. ITHTB.LE.1)THEN
write(98,*)'**** OUT OF BOUNDS *********'
! call flush(98)
The model does not crash (go unstable) when these messages are produced, but I am concerned that these messages are occurring. Do they indicate that something is going wrong in the Kain-Fritsch convection scheme, or are they just diagnostic messages that shouldn't be cause for concern?
Thanks for any feedback on this.
