I found the formula changes little when compared to normal magnitude interpolation.
Changes are larger in areas with high vorticity.
In the image below, I inverted the direction of the 25.4 wind arrow to create an extreme situation.
The left side uses regular magnitude interpolation and the right side uses the weird formula.
While magnitude interpolation keeps the magnitude (speed) of the wind vector when
we move between two arrows, the formula goes to 0 and back.
Which one looks better ?
