Plot new TC-Diagnostics output from TC-Pairs.

[JohnHalleyGotway]

Describe the New Feature

The key targets for plotting development in this issue are (from the 04/07/2023 project-wide meeting):

1. Display the distributions of diagnostics by storm, by season, by model
2. Skew-Ts
3. Time series of diagnostic values for forecasts

More details:
1. Display the distributions of diagnostics by storm, by season, by model

• This will be useful for researchers and forecasters wanting to understand retrospective evaluation of model performance.
• E.g., shear vs. different models
• By default, the filtering is homogeneous.
• METplotpy has transitioned the Rscript codes to do boxplots based on errors, so it’s just a matter of switching these over from errors to diagnostics.
• The new TCpairs line type is TCDiag which comes after MPR has paired values, not columns. Not trivial to adapt.
• This could also be conditioned by errors or thresholded diagnostic value (e.g., low shear).

2. Skew-Ts

• This will be useful for forecasters - sanity check on model’s atmospheric structure, but also to check to see if there are aspects not captured by the standard diagnostics (e.g., mid-level jet, SAL inversion, etc.).
• These are area-averaged values, not a sounding at a point.
• In theory, the point soundings COULD be done from the cylindrical grid and compared to the large-scale.
• But for now, focus on one sounding - the single values out of the diagnostics without regard to the area it has been averaged over (can be read directly from the ASCII or TC-Pairs, if included).
• This low hanging fruit. Just plot the column of single numbers for each forecast hour.

3. Time series of diagnostic values for forecasts

• This is a real-time type of plot for forecasters
• Similar to what CIRA is producing. Representing what is in the current diagnostic file.

More information:

• 1 and 3 would fit under the guise of the TC-MPR plotter (a doable modification).
• 2 would probably be separate from TC-MPR plotter. Probably the most viable task to tackle first.
• Start by using the diagnostic data from TC-pairs.

This issue is related to:

• Create an initial development version of a new TC-Diag tool to support the computation of tropical cyclone diagnostics MET#2168 defines a new MET tool named TC-Diag.
• Enhance TC-Pairs to read hurricane model diagnostic files (e.g. SHIPS) and TC-Stat to filter the new data MET#392 enhances TC-Pairs to read the Tropical Cyclone Diagnostics output from TC-Diag (or other sources) and incorporate it into the output of the TC-Pairs tool.
• Load new TC-Diagnostics output from TC-Pairs. METdataio#87 loads the updated TC-Pairs output into a MET database.
• Support reformatting the TCDIAG line type written by the TC-Pairs tool  METdataio#240
• Create documentation and testing for TCMPR plotting code  #383 creates documentation and testing for TCMPR plotting code
• Enhance TCMPR plotter to read TCDiag lines and filter by one column and plot another column #342 enhances TCMPR plotter to read TCDiag lines and filter by one column and plot another column

For now, this task will focus on developing python-based plotting in METplotpy.
