Re: ncl wrf_vector

Hi Bin,

There's a bug in wrf_vector that causes gsnFrame and gsnDraw to be False no matter what you set them to.

I have fixed this bug internally, but meanwhile, to work-around this, you need to call draw and frame yourself:

  vector = wrf_vector(fn1,wks,u10,v10,res)
  draw(vector)
  frame(wks)
