Update WW3 cap for 2-way ocean-wave coupling

[binli2337]

Pull Request Summary

The file wav_import_export.F90 located at model/src will be updated to convert a missing value to zero for the HAFS application.

Description

The HAFS application in the ufs-weather-model will be updated to include 2-way ocean-wave coupling capability. The related CMEPS component will be updated to interpolate ocean-current fields from MOM6 grid to WW3 grid. Since regional MOM6 domain and regional WW3 domain do not completely overlap, a missing value is assigned to the interpolated fields in the non-overlapped regions. In the CMEPS component, the missing value is 9.99e20.
To prevent a model crash, a short-term solution is to convert the missing value to zero in the file model/src/wav_import_export.F90. In the future, the ocean-current fields in the non-overlapped regions can be provided from a global MOM6 output.

Commit Message

Converting a missing value to zero for the imported ocean-current fields.

Check list

• Branch is up to date with the authoritative repository (NOAA-EMC) develop branch.
• Checked the checklist for a developer submitting to develop.
• If a version number update is required, checked the updating version number checklist.
• If a new feature was added, a regression test for testing the new feature is added.

Testing

• How were these changes tested? These changes have been tested using the ufs-weather-model regression test system. Five HAFS tests with the regional WW3 component will change results since a modified mod_def.ww3 file is used to include additional output fields.
• Are the changes covered by regression tests? (If not, why? Do new tests need to be added?)
• Have the matrix regression tests been run (if yes, please note HPC and compiler)?
• Please indicate the expected changes in the regression test output, (Note the list of known non-identical tests.)
• Please provide the summary output of matrix.comp (matrix.Diff.txt, matrixCompFull.txt and matrixCompSummary.txt):

This needs to be isolated so as to not to affect other users of the WW3 mesh cap.

@binli2337 is there a corresponding ufs-weather-model PR or did I miss it?

[JessicaMeixner-NOAA]

@binli2337 We need a ufs-weather-model PR to correspond with this. I did a quick test and my log is here:
/work2/noaa/marine/jmeixner/hercules/PR_WW3/ufs-ww3pr1348/ufs-weather-model/tests/logs/RegressionTests_hercules.log

I did not get the same results as you - all tests were the same, which honestly I was a little surprised about. I agree with @DeniseWorthen though- it would be best if this was isolated with a flag to turn on/off this feature.
