A method to perform a baroclinic wave experiment by Polvani et al. (2004) is described.
This experiment does not require additional data, such as SST data. Thus, the experiment is performed with the following 3 steps:
Let us move to the top directory of dcpam5 src tree (assuming dcpam5-YYYYMMDD in the following example). Here, we perform an experiment in ../dcpam5-exp/p04-exp directory. Please create the directory and enter there as follows:
$ mkdir -p ../dcpam5-exp/p04-exp $ cd ../dcpam5-exp/p04-exp
Then, pleaase create the directories for executable files and configuration files as follows:
$ mkdir bin $ mkdir conf
Finally, executable files and configuration files are copied as follows:
$ cp ../../dcpam5-YYYYMMDD/src/main/dcpam_main bin $ cp ../../dcpam5-YYYYMMDD/src/main/init_data bin $ cp ../../dcpam5-YYYYMMDD/exp_setup_files/*.conf conf
Note that you can perform an experiment in any directory by using executable files and configuration (NAMELIST) files.
Create initial data file "init_T21L20.nc" using "bin/init_data" and "conf/init_data_p04_T21L20.conf"
$ ./bin/init_data -N=./conf/init_data_p04_T21L20.conf

Using an executable files 'dcpam_main' and a NAMELIST file dcpam_p04_T21L20.conf, execute 'dcpam_main' as follows. This program will be finished in few minutes - tens of minutes.
$ ./bin/dcpam_main -N=./conf/dcpam_p04_T21L20.conf | tee p04.log

In this case, 12 days integration is performed. Resolution is T21L20 (Number of grid points of longitude, latitude is 64, 32, and number of vertical layer is 20). History data are output to 'U.nc' and 'Temp.nc' etc., and a restart data is output to 'restart.nc'.
If you would like to keep the results of the numerical experiment, please create a sub directory ("data01" for example), move the files, and keep the current directory neatly.
$ mkdir data01 $ mv *.nc *.log data01/
You can output the results of the numerical experimet concurrently with the execution. Please refer to "Change output settings" in Change experimental setup and try to configure "FilePrefix" variable in NAMELIST ">ool_historyauto_nml".
