500mb geopotential and storm tracks in ERA5 #66

Closed sandrocalmanti closed 1 year ago

sandrocalmanti commented 1 year ago

Notebook description

This is the quasi-final form of the notebook on storm-tracks as seen from ERA5.

The code is complete, it does everything it has to do, but needs to be optimized. For example a mapping function would be more efficient and readable than repeating the same lines of code.

In the notebook, the user can select the season of interest soi to visualize the corresponding season

Meanwhile, I'm working on the description of the results and take-home messages to complete the notebook

Best!

Hi @sandrocalmanti,

Looks good, and the way you are caching data is correct.

I think we can make use of plot.projected_map to make the plots, but I need to try. I'll take a look this afternoon and I'll probably add a template for this use case.

Hi @sandrocalmanti,

Sorry about the delay, busy times. I've added a template for this use case. I didn't change much, I mainly tried to avoid repeating the same code.

Here is the template: https://github.com/bopen/c3s-eqc-toolbox-template/blob/main/notebooks/wp5/era5_storm_track.ipynb

Here is the notebook executed: https://gist.github.com/malmans2/f9148b6288de510b47495d19be30fc6e

Thank you @malmans2

After some discussion with my collegues I have implemented a small extention to this notebook, in order to compare the present climate with the backward extention of ERA5 to 1940.

I have added a new dimension period as done in other notebooks on the reanalysis.

It seems to work nicely quite to the end until I get a Memory error.

I have tried to clear the kernel and restart, in case anything went wrong. Is there anything we can do about that? Am I using the caching correctly?

Cheers

Sandro

Hi @sandrocalmanti,

Especially when there are many users logged in, the VM is struggling to compute all seasons at once. Let's cache seasons separately.

I've updated the template: https://github.com/bopen/c3s-eqc-toolbox-template/blob/main/notebooks/wp5/era5_storm_track.ipynb Here is the template rendered: https://gist.github.com/malmans2/c662d0899b9a7bb8d38542611e32124c

Let me know if it works OK.

sandrocalmanti commented 1 year ago

I have checked the rendering and it's just fine.

Theank you.
