Reconstructing the wind field from vorticity and divergence over finite domains
Sep 21, 2023
@dopplershift We have a preliminary version of the vectorized code that reproduces the Clark Evans notebook. What indeed are the next steps ? |
The first step is to open a draft PR so we can see concretely the code and give better design feedback, including addressing some of the issues above. |

What should we add?
We suggest to add the following new functionality which implements a reconstruction of the wind field from vorticity and divergence over a limited domain. It can be used to quantify, among others, how clouds induce a far-field circulation around them – see for example [Oertel and Schemm 2021](https://doi.org/10.1002/qj.3992 .)
Specifically equation (8) and (9) of that paper.
How
We suggest to follow the notebook [Clark Evans notebook](https://github.com/evans36/miscellany/blob/main/Vorticity%20and%20Divergence%20Inversion.ipynb .) The interface will support xarray data structures as is used by other APIs of MetPy.
What's next
While I am looking to implement a first version of this myself I do welcome support and inputs.
Specifically the first version of this functionality will cover these aspects
Future versions could possibly include
