[ncl-talk] wind vector

[Kyle Griffin]

I'm not Dave, but I'll go ahead and say "no" - CurlyVectors are more akin
to streamlines in that they don't exist at any one "point" but rather get
longer and turn with the wind as magnitude increases. You can't simply turn
off the CurlyVector in some areas as it would break up the streamline by
falling below an arbitrary magnitude. vcMinMagnitude seems to look the best
with either LineArrow or FillArrow glyphs, in my experience.

Good luck!
