Hi,

For arrow representation, PARTVELVEC from the IDL Astro library accepts
irregular fields as input
(http://idlastro.gsfc.nasa.gov/ftp/pro/plot/partvelvec.pro)

For windbarbs, I don't know. A good idea would be to start from
PARTVELVEC and implement the barb thing... If you do it, I'm interested
in the final product too ;-)
