Using Regrid2 to display wind barbs

[ricardo marcelo da silva]

I'm not sure if regrid2 recognizes vector expressions like "u;v".
Probally you'll need do define new regridded vars or use a long
line.

long line:
d regrid2(ugrdprs(t=1,lev=1000),0.5,0.5,bl);regrid2(vgrdprs(t=1,lev=1000),0.5,0.5,bl)

;)
