# JHWRF_MERGE -- merges the storm-removed large-scale fields with the
#     new vortex, possibly after GSI has processed the data.  This job
#     waits for the 126hr JHWRF_NMM_REAL to complete, after which the
#     forecast and post-processors should be submitted

# Last modified: Samuel Trahan, April 5, 2012.

# *** Operational Workflow ***

# Submitted: After JHWRF_NMM_GSI_D1 and JHWRF_NMM_GSI_D2 complete,
#     even if one or both fail.  This script recovers from any failures.
# Submits: The forecast and three post-processors:
#
#     JHWRF_FORECAST -- TWO CASES: with or without ocean coupling
#       With ocean coupling if MODEL=COUPLED in
#        the $stormlabel.holdvars.txt,   *AND*
#        the ${COMOUT}/ocean_status.${STORM}${STORMID}.${PDY}${cyc} 
#        contains RUN_COUPLED=YES
#       Otherwise,
#        submitted without ocean coupling
#       See the JHWRF_FORECAST for details.
#
#     JHWRF_TRACK_SWATH -- tracker and swath input job.
#     JHWRF_POST -- three copies of this job with different variables:
#
#       1. Non-satellite synoptic hours: 
#         POST_FIRSTHOUR=0, POST_LASTHOUR=126
#         POST_INCREMENT=6, POST_MODE=NONSAT
#
#       2. Non-satellite intermediate hours: 
#         POST_FIRSTHOUR=3, POST_LASTHOUR=123
#         POST_INCREMENT=6, POST_MODE=NONSAT
#
#       3. Satellite synoptic hours: 
#         POST_FIRSTHOUR=0, POST_LASTHOUR=126
#         POST_INCREMENT=6, POST_MODE=SAT
#
#     See the JHWRF_POST.sms for details.

# Primary scripts and parameter files:
#   scripts/exhwrf_merge.sh.sms -- passes control to hwrf_merge.sh
#   ush/hwrf_merge.sh -- performs various vortex cutting and pasting
#      operations on binary files to produce the final input to
#      the forecast job (wrfinput_d01, wrfanl_d02, wrfanl_d03)

# Primary executables:
#   exec/hwrf_bin_io -- creates flat fortran binary files containing
#      data taken out of a WRF output (wrfout, wrfanl or ghost) file
#   exec/hwrf_diffwrf_3dvar -- para-only; needed to do the same for
#      WRF NetCDF output files
#   exec/hwrf_inter_2to1 -- inter-domain interpolation code
#   exec/hwrf_inter_2to2 -- inter-domain interpolation code
#   exec/hwrf_inter_2to6 -- inter-domain interpolation code
#   exec/hwrf_guess -- produces a first guess "fake" cyclone
#      based on a bogus storm
