Can someone please explain the usefulness of the 2PVU maps? I feel as if just recently I’ve noticed them referenced more on the boards. Do you look at them as another way to view the vorticity, similar to looking at the h5 vorts?
I was trying to read a little more here, but this appears to be a slightly different topic.
