Diagnostic for calculating Lamb Weathertypes #3691

thomaskroi1996 · 2024-06-27T08:52:52Z

Hello everyone!

At the Wegener Center in Graz, Austria, we have been doing some research with Lamb Weathertypes for quite some while now, and recently started developing a diagnostic for ESMValTool to make things easier, and potentially be of use for others!

The features are:

Calculate the 27 Lamb Weathertypes over a region specified in the corresponding recipe
Plot means, anomalies as well as standard deviations for those weathertypes for psl, tas and prcp
Combining the weathertypes based on precipitation patterns over an area specified in the corresponding recipe as done here: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020JD032824 (Table 2)
Create the same plots for those combined weathertypes

The weathertypes are calculated for ERA5 and model data, and the precipitation data for correlation calculations are taken from ERA5 and E-OBS.

The branch we are working on is called weathertyping_wegc.

We are happy to discuss this project with the community, get some feedback and features you would like to see!

Thank you very much and with kind regards,

Thomas Kroißenbrunner and Martin Jury

@thomaskroi1996 glad to see this in PR form, well done 👏 🍺 I can perform a technical review of it, but for a scientific review, I'd suggest we think who's the closest expert amongst us to perform the review. Just a couple questions before the review, please:

are you happy to have this reviewed now, or you still working on it? If work is still to be performed, then I'd recommend you convert this PR to a Draft PR, and when it's ready, make it back ready for review;
to find the best scientific reviewers, it'd be good if you could suggest one or more folks that already have experience with this type of diagnostic, if not maybe we can ask the list (scientific reviewers, which I can invoke via a GitHub tag)

Cheers 🍺

thomaskroi1996 · 2024-06-27T14:42:52Z

@valeriupredoi Hey there! I am still doing some work, and definitely have to do all the tests, therfore I will convert it to a draft now, thank you so much!
As for the 2nd point, I can talk to my supervisor next week, and then maybe we have some suggestions for scientific reviewers, in which case I will reply to you here again!

Cheers! 🍻

thomaskroi1996 · 2024-08-19T08:51:17Z

@valeriupredoi Hello! :) I have now finished all the main work now, and implemented everything we wanted to! Now I think it is time for the technical review, correct? Thank you so much for all the help!

valeriupredoi · 2024-09-19T16:04:47Z

@ESMValGroup/scientific-lead-development-team any of you good folk want to have a look at this new diagnostic, and sign up for a scientific review, please? It looks very cool, but unfortunately, I am no expert in weather types, all I know is "rainy" in Britain 🇬🇧 😁

bettina-gier · 2024-09-19T16:08:54Z

I'll look at it tomorrow, not an expert in weather types but can still see if each part is scientifically sound, esp if there's a linked paper to compare it to!

wonderful, many thanks, Tina 🍺

This looks like a great contribution to the ESMValTool! I gotta admit I didn't read all the python code in the utils file, but the formulas seem like the paper you linked and the plots my run got looked like the ones you put in the documentation - units look fine to me and patterns reasonable. So general scientific review gets a big check. I've got some general points though:

On the technical side (YO @valeriupredoi I thought I was doing the sci review!):

Your provenance doesn't seem right, I got the files in the wrong folder (where I started the diagnostics), and I'm not sure which of your output files they actually belong to, calling them the same as your output files is recommended. I think provenance for the plots is missing (best to include it in your plotting functions).
You're outputting both pdf and png files hardcoded, while we have the input_file_type variable in the User config, would be cool to use that instead

On the scientific side, I've got less required changes since the output looks reasonable, but maybe some more quality of life:

Your two observational datasets seem pretty hardcoded, how much of that is that required or could you (within reasonable time) check if you could support other observations/reanalysis? The more modular the better.
Could you put more information on the selection of the extracted region, what is necessary for the computation, what for the output? The recipes use two different extract_regions. It might be nice to know for the user which of these they can change.
Similarly, some of your recipes use different timeframes - obviously to account for the available data - but none of your filenames or plot titles mention the period used for the computation, just "mean". I think this would be nice to add. Maybe also the name of the dataset in the plottitle, the first two plots in the documentation is very similar until you read the caption.

+        plt.savefig(f'{output_path}/{dataset_name}_{ensemble}_'
+                    f'{wt_string}_rel_occurrence.pdf')


I would suggest to only output one plot filetype using the cfg['output_file_type'] from the user_config. You could use the get_plot_filename function from esmvaltool.diag_scripts.shared

"Figures should be saved in the plot_dir, either in both .pdf and .png format (preferred), or respect the output_file_type specified in the [User configuration file]."
I found this in the "Making a New Diagnostic or Recipe", which is why I decided to hardcode it in the first place! Writing only one plot with output_file_type would certainly save some time though!

Huh, that shows you how much I read the documentation =D I personally prefer using the output_file_type but if it says so in the documentation you can keep it if you want to make as few changes as possible.

:D Thank you for the quick reply! I think it certainly makes sense to let the user have a say in the output file type! I will also talk to my supervisor, and then decide! Thank you!

All your calls to log_provenance are only giving filenames without the paths, resulting in the provenance files being created in the folder where I start the tool, not together with the files.

@valeriupredoi @bettina-gier Hello both of you and thank you so much for the replies! Not sure how I missed that, so sorry for the late reply!

Thank you so much for the input, I will correct everything as soon as i have some time on my hands! Unfourtunately I have switched to a different project, but it should be fine to allocate some hours throughout the next weeks to work on the mistakes/improvements!

thomaskroi1996 · 2024-09-29T11:50:37Z

@valeriupredoi @bettina-gier Hello! Currently the Circle CI test seems to fail because I use "from wt_utils import *", just thought i would comment that here!

Also the minor things are dealt with now, leaving only including the possibility for more observational datasets (for which I will talk to @mwjury), and compacting the recipes!

I also need to rerun the recipes so that I can update the documentation with the new plots etc., however since I currently need our computational resources for another project, hopefully next week I can tend to it!

Thanks again for the great input! :)

valeriupredoi · 2024-10-02T15:58:33Z

@thomaskroi1996 take your time, no rush at all! I can help sometime next week too, knock off some of those Flake8 issues. You are absolutely correct - and my bad - Flake8 flags star imports - always discouraged people do that, but looks like Flake8 is now the Punisher 😁

thomaskroi1996 · 2024-10-03T11:41:28Z

@valeriupredoi Alright, over the next couple of days I will import only the necessary functions, and I only just discovered that there were more issues with the code, even though flake8 didn't output any anymore, I should have also run pytest!

One issue is "too many local variables". Those started popping up because I tried to fix "too many arguments" by passing Dicts and then reassigning them to local variables in the functions! Those are all marked as minor issues, should I fix those issues? In my opinion I think the way I have it now makes it a bit more readable and less clustered, and if I remember correctly I once saw a PR where it was said that a few of these issues are okay!

That's great you tried to clean up, but don't worry too much about the "too many variables" linter message, scientific computing for ESMs is bound to have lots of variables anyway 🍺
