Question about wrf_vector

Hello everyone,

I tried to make a simple wrf vector plot, but got blank. The following
is the code (I copied from ncl webpage and made some small modification
to replace the nc file). WRFUserARW.ncl was newly downloaded from ncl
webpage.
Does any have any idea where the problem is?
By the way, I am using NCLVersion 5.0.0
Thanks a lot!

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
; load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl"
load "./WRFUserARW.ncl"
begin

a = addfile("wrfout.10km.lonlat.nc","r")

wks = gsn_open_wks("x11","test")
res=True
u10 = wrf_user_getvar(a,"U10",0) ; U component of the wind at 10m
v10 = wrf_user_getvar(a,"V10",0) ; V component of the wind at 10m
; respect to speed use False

vector = wrf_vector(a,wks,u10,v10,res)

end
