GSI CYCLING RUN ARW BACKGROUND

Set up WRF-ARW run at 12Z

For this step of WRF-ARW run at 12Z of August 12, 2018, we will use the GSI analysis output wrf_inout from the online exercise 05 as the initial fields to launch 6-hour WRF forecast.

First, make sure you have a compiled code of the latest WRF-ARW code (V4.0). You can download the boundary condition for WRF from link . 

Please follow the WRF tutorial and documents for the details of the WRF system application. 

Here we provide the namelist file for reference of WRF run: 
namelist.input

Running the ARW and checking the forecast results

The ARW can be run by creating a run script run_wrf.ksh and submitting it in the run directory: 

bsub < run_wrf.ksh

It will take a few minutes to finish. Once done, users should see the forecast files in each forecast hour from 12z to 20z like 
wrfout_d01_2018-08-12_HH_00:00:00.

The contents of this run directory are provided in the following list .

The ARW standard output file rsl.out.0000 is povided for reference.
