Hi Chad,
You are correct in that you should use gsn_csm_pres_hgt_vector.
we just don't have an web examples of that template wrt time but it
certainly can handle that.
you will need to change your vector style to windbarb
res@vcGlyphStyle = "WindBarb" ; select wind barbs
etc.
note that when putting vectors or barbs on a vertical plot it may be
necessary to scale your vertical velocity so that u and or v does not
overwhelm it. I have seen OMEGA used over W in these situations as well.
if you plan to do this via time, what wind components do you plan to use?
the advantage of lat/lon on the x axis is that choosing the component is
simplier.
cheers,
sylvia
