Now we are bringing in the ensembles & as a reminder to folks why @metpy.bsky.social is a powerful tool since vorticity isn't a field in the ensembles like it is in the deterministic models. However, we can use metpy.calc to calculate vorticity from the u & v wind components in the ensemble field.

I strongly recommend to any professors who teach Computer Applications in Meteorology to show MetPy to the students. The way to get more meteorology students interested in Python is to show them how to make cool weather maps via data analysis so students can see how Python relates to meteorology.
