WRF warm-start steps

Warm-starting in WRF involves using a previous model run as initial conditions for a new run, rather than starting from scratch. This can save computational time and improve accuracy by providing a more realistic starting point.
Here are the general steps for warm-starting in WRF:
1. Run a baseline simulation to generate initial conditions for the model.
2. Save the output from the baseline simulation, including the initial conditions and any other necessary files (e.g. namelist.input, met_em* files, etc.).
3. Modify the namelist.input file for the new simulation to specify the start time and end time for the new simulation, as well as any other necessary settings (e.g. boundary conditions, physics options, etc.).
4. In the new simulation, set the restart flag to .TRUE. in the namelist.input file.
5. Copy the necessary files from the baseline simulation (including the initial conditions) to the new simulation directory.
6. Run the new simulation, which will use the previous simulation's output as initial conditions.
7. If desired, repeat steps 2-6 to continue the warm-start process for additional simulations.
It's important to note that there may be some additional steps or considerations depending on the specific setup and requirements of your model runs. It's always a good idea to consult the WRF documentation and/or seek advice from experienced WRF users or developers if you're unsure about any aspect of the warm-start process.
