HWRF Online Tutorial V3.9a | Additional Exercises > Alternate Configuration

Create user specific conf file

In this exercise, you will create a configuration of HWRF for a Western Pacific storm, CHABA 21W, initialized on October 4, 2016, at 00 UTC. For this case, you will run a coupled atmosphere-ocean forecast with no data assimilation using GRIB files as input for initial and boundary conditions.NOTE: Sections 3.7 and 3.8 of the HWRF Users Guide will be very helpful when running this exercise!

Each of the above pieces of information is configurable through variables available in either the configuration files in the parm/ directory or in the global_vars.ksh file in the wrappers/ directory.

To write your own configuration file, follow the directions below.

1. Identify pieces of information that will be configured in global_vars.ksh, and edit that file.ANSWER
2. Identify items related to work flow configuration. ANSWER
3. Open a new file for editing in parm/ named hwrf_tutorial.conf
4. Include sections, variables, and values for each of items identified above.ANSWER

Open a file for editing, named hwrf_tutorial.conf and include the following:

• [config]
  run_gsi=no
  run_ocean=yes
  use_spectral=no
  gfsinit_type=1

  [prelaunch]
  basin_overrides=no

 

Add this config file to your launcher_wrapper script:

• ${HOMEhwrf}/scripts/exhwrf_launch.py "$YMDH" "$STID" "$CASE_ROOT" "$HOMEhwrf/parm" \
  "config.EXPT=${EXPT}" "config.startfile=${startfile}" \
  "config.HOMEhwrf=$HOMEhwrf" "config.case_root=$CASE_ROOT" \
  "$HOMEhwrf/parm/hwrf_v3.9a_release.conf" \
  "$HOMEhwrf/parm/hwrf_tutorial.conf" \
