ncl画流场图

simon7

下面脚本是官网画流场图的脚本，我把文件换成我自己的，但是画出来内容是空的，也没有经纬度信息，但我的文件有经纬度的啊，请问要怎么改呢？
; stream_5.ncl

begin
  f = addfile("../wrfout_d02_2009-09-16_06:00:00","r")
  ;u1   = f->U(:,0,:,:)
  ;print(u1)
  u    = f->U(0,0,:,:)    ; read in example data [2D only here]
  v    = f->V(0,0,:,:)
; =================================================;

wtype = "x11"
;
; These lines have been commented out due to the fact that they generate
; an excessively large plot.
; wtype@wkWidth = 2500
; wtype@wkHeight = 2500
  wks = gsn_open_wks(wtype,"stream")
; The following line is not needed, and has been commented out.
; wks  = gsn_open_wks("ps","stream")             ; open a ps plot
  res = True

  res@stLineThicknessF      = 5.0         ; default is 1.0
  res@stLineColor = "NavyBlue"
  plot = gsn_csm_streamline(wks,u,v,res)
end

你没有读取经纬度信息怎么有经纬度呢，建议用ncl里的WRF专用函数，可以直接画出wrf的底图
