HWRF Online Tutorial V3.9a | Merge

Run Merge

Start by entering the wrappers directory:Once the HWRF atmospheric initialization has been completed with the use of the vortex relocation and data assimilation, the adjusted ICs on all grids must be merged to provide the final ICs for the HWRF 5-day forecast.  

cd ${SCRATCH}/hwrfrun/wrappers

Next, copy and edit the qsub template according to the example.

Finally, submit the job:

qsub run.merge.csh

The merge job should take approximately 5 minutes to run. However, your runtime may vary.

Status Check: In the standard output file from the batch script, you will find the line INFO: exhwrf_merge has completed.

Visualization of output
