Web20 aug. 2024 · The relationship between `absolute_vorticity` and `vorticity` in MetPy is `absolute_vorticity` = f + `vorticity` `vorticity` calculates the vertical vorticity and represents the combination of curvature and shear terms. The equation would be: dv/dx - du/dy I'll go ahead and add that equation to our docs to make that clearer for everyone.
