Scientific Objective
The TC-RMW tool regrids tropical cyclone model data onto a moving range-azimuth grid centered on points along the storm track. This capability replicates the NOAA Hurricane Research Division DIA-Post module.
Version Added
METplus version 3.1
Datasets
Forecast: GFS GRIB2
Observation: Automated Tropical Cyclone Forecasting System (ATCF) A Deck
Climatology: None
Location: All of the input data required for this use case can be found in a sample data tarball. Each use case category will have one or more sample data tarballs. It is only necessary to download the tarball with the use case’s dataset and not the entire collection of sample data. Click here to access the METplus releases page and download sample data for the appropriate release: https://github.com/dtcenter/METplus/releases This tarball should be unpacked into the directory that you will set the value of INPUT_BASE. See Running METplus section for more information.
METplus Components
This use case utilizes the METplus TCRMW wrapper to search for the desired ADECK file and forecast files that are correspond to the track. It generates a command to run the MET tool TC-RMW if all required files are found.
METplus Workflow
Beginning time (INIT_BEG): 2014101312
End time (INIT_END): 2014101312
Increment between beginning and end times (INIT_INCREMENT): 6H
Sequence of forecast leads to process (LEAD_SEQ): begin_end_incr(0, 24, 6)
TCRMW is the only tool called in this example. It processes the following run times:
METplus Configuration
METplus first loads all of the configuration files found in parm/metplus_config, then it loads any configuration files passed to METplus via the command line, i.e. parm/use_cases/model_applications/tc_and_extra_tc/TCRMW_fcstGFS_fcstOnly_gonzalo.conf

MET Configuration
METplus sets environment variables based on user settings in the METplus configuration file. See How METplus controls MET config file settings for more details.
YOU SHOULD NOT SET ANY OF THESE ENVIRONMENT VARIABLES YOURSELF! THEY WILL BE OVERWRITTEN BY METPLUS WHEN IT CALLS THE MET TOOLS!
If there is a setting in the MET configuration file that is currently not supported by METplus you’d like to control, please refer to: Overriding Unsupported MET config file settings
