METplus Practical Session Guide (Version 5.0) | Session 6: Track and Intensity > METplus Use Case: TC-Stat

The TCPairs use case utilizes the MET TC-Pairs tool.

Optional: Refer to the MET Users Guide for a description of the MET tools used in this use case.
Optional: Refer to the METplus Config Glossary section of the METplus Users Guide for a reference to METplus variables used in this use case.

Change to the ${METPLUS_TUTORIAL_DIR}

1. See what TCPairs use cases are available in met_tool_wrapper directory and run one

There is an example of using TC-Stat with no delineation between Extratropical Cyclones as well as Tropical Cyclones

This use case is focused on summarizing the ASPEED data including data from 24 hours before landfall. Keep in mind the summary information will be written out. Also, because the -dump_row flag was set, output will be placed in the file {TC_STAT_OUTPUT_DIR}/tc_stat_summary.tcst

2. Run the use case:

3. Review the output and input files:

Look at the output written to the directory specified as TC_STAT_OUT_DIR

You will notice this looks very similar to output from TCPairs, confirmed by noting the LINE_TYPE is TCMPR. While this is helpful, the outcome of the SUMMARY job is part of standard output from the tool, unless the -out flag is used when calling the tool. Standard output will be found in the location specified by the TC_STAT_OUTPUT_TEMPLATE. For this example, the file will be named job.out

Open the standard output file in ${METPLUS_TUTORIAL_DIR}/output/TCStat/, with the filename job.out. Inside, you'll find:

The headers indicate that this information includes details about the distribution of data as well as measures to generate plots of Frequency of Superior Performance. The description of each column can be found at: https://met.readthedocs.io/en/latest/Users_Guide/index.html. The other notable result is that most columns are listed as NA. This is because the -column setting is listed as 'ASPEED' with quotes around the column name. The quotes appears to be an error, probably a remnant of a previous METplus version. Let's change that and see what happens.

4. Copy METplus config file, modify and re-run

5. Review output

The values of ASPEED and TK_ERR are now available. Let's take one more step to demonstrate additional capability.

6. Copy METplus config file, modify and re-run

7. Review output

Open standard output file in ${METPLUS_TUTORIAL_DIR}/output/TCStat_run3 under the name job.out and scroll down to the bottom.

There are now 48 lines with lines summarizing AMAX_WIND and TK_ERR across 24 STORM_NAMEs. The information for FSP columns is zero because there is only data for 1 model being summarized.
