""" CyclonePlotter: Extra-TC Tracker and Plotting Capabilities ========================================================== model_applications/tc_and_extra_tc/CyclonePlotter_fcstGFS_obsGFS_UserScript_ExtraTC.conf """ ############################################################################## # .. contents:: # :depth: 1 # :local: # :backlinks: none ############################################################################## # Scientific Objective # -------------------- # # Once this method is complete, a user-created extra TC track file # for the valid date of interest (YYYYMMDDHH) will have been created, # paired up by TCPairs, and global storm tracks # for the valid date of interest will be plotted by CyclonePlotter (PlateCaree projection) ############################################################################## # Version Added # ------------- # # METplus version 5.1 ############################################################################## # Datasets # -------- # # | **Forecast:** Automated Tropical Cyclone Forecasting System (ATCF) Adeck # | /path/to/{init?fmt=%Y}/trak.gfso.atcf_gen.glbl.{init?fmt=%Y} # # | **Observation:** Automated Tropical Cyclone Forecasting System (Bdeck) # | /path/to/{init?fmt=%Y}/trak.gfso.atcf_gen.glbl.{init?fmt=%Y} # # **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 :ref:`running-metplus` section for more information. ############################################################################## # External Dependencies # --------------------- # # You will need to use a version of Python 3.6+ that has the following packages installed: # # * cartopy # * matplotlib # ############################################################################## # METplus Components # ------------------ # # This use case utilizes Python user script-created output files that are accessible via the TCPairs wrapper. # Due to the nature of the source file (already tracked extra TCs), the TCPairs wrapper is passed the "Adeck" file for each storm twice: # once as the adeck or forecast file, and once as the bdeck or analysis file. Essentially, TCPairs is matching a forecast to itself. # It then uses the CyclonePlotter wrapper to create a global plot of storm tracks for the desired day of interest (YYYYMMDDHH). ############################################################################## # METplus Workflow # ---------------- # # **Beginning time (INIT_BEG):** 20201007 # # **End time (INIT_END):** None # # **Increment between beginning and end times (INIT_INCREMENT):** None # # **Sequence of forecast leads to process (LEAD_SEQ):** None # # TCPairs is the first tool called in this example, then CyclonePlotter # is the second (and final) tool called in this example.

These storms are put into separate storm files, to better mimic how TC storms are # typically passed to TCPairs. # # .. dropdown:: parm/use_cases/model_applications/tc_and_extra_tc/CyclonePlotter_fcstGFS_obsGFS_UserScript_ExtraTC/extract_opc_decks.py # # .. highlight:: python # .. literalinclude:: ../../../../parm/use_cases/model_applications/tc_and_extra_tc/CyclonePlotter_fcstGFS_obsGFS_UserScript_ExtraTC/extract_opc_decks.py # # For more information on the basic requirements to utilize Python Embedding in METplus, # please refer to the MET User’s Guide section on `Python embedding `_. ############################################################################## # User Scripting # -------------- # # User Scripting is not used in this use case. ############################################################################## # Running METplus # --------------- # # Pass the use case configuration file to the run_metplus.py script along # with any user-specific system configuration files if desired:: # # run_metplus.py /path/to/CyclonePlotter_fcstGFS_obsGFS_UserScript_ExtraTC.conf /path/to/user_system.conf # # See :ref:`running-metplus` for more information. ############################################################################## # Expected Output # --------------- # # A successful run will output the following both to the screen and to the logfile:: # # INFO: METplus has successfully finished running. # # Refer to the value set for **OUTPUT_BASE** to find where the output data was generated. # Output for this use case will be found in **tc_pairs/201412** (relative to **OUTPUT_BASE**) # and will contain the following files: # # * decks/adeck/adeck.2020100700.xxxx.dat # * tc_pairs/tc_pairs.2020100700.xxxx.tcst # * cyclone/20201007.png # * cyclone/20201007.txt # # where "xxxx" is the unique four digit storm identifier for TCPairs wrapper to use. ############################################################################## # Keywords # -------- # # .. note:: # # * TCPairsToolUseCase # * SBUOrgUseCase # * CyclonePlotterUseCase # * TropicalCycloneUseCase # # Navigate to the :ref:`quick-search` page to discover other similar use cases. # # # # sphinx_gallery_thumbnail_path = '_static/tc_and_extra_tc-CyclonePlotter_fcstGFS_obsGFS_UserScript_ExtraTC.png'
