Subject: perpetual run for CCM2 on shavano
To: ccm-users@ncar.ucar.edu
Date: Thu, 4 Jan 1996 18:25:32 -0500 (EST)
Dear CCM2 users:
Unlike in CCM1, CCM2 put "anncyc" parameter into the code (data.F)
rather in namelist file. Default "anncyc=.true.".
I am running CCM2.1 version on shavano for perpetual case in T42
What I did are:
1) copy src code into my directory and change 'anncyc=.false.' in data.F;
2) use runmodel.job with modified case (set mode 1) and other needed
changes in the script.
3) initial data is /CSM/ccm2/386T42/DEC1604 (detailed in attached namelist
below)
What I got is the blowout of model about the 20th model day. Does anyone
have some of experinces on the perpetual run of CCM2.1 ? should I
need more changes to make the model in perpetual mode.
Any suggestion and help are greatly appreciated.
