[ncl-talk] wind vector query

[Kunal Bali]

Dear NCL users


i am trying to plot the wind vector data using attached script but getting
errors (below the scripts )

variables are U and V

;----------------------------------------------------------------------

load "/usr/local/lib/ncl/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "/usr/local/lib/ncl/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "/usr/local/lib/ncl/lib/ncarg/nclscripts/csm/shea_util.ncl"

begin
;---Read data
  a   = addfile("/home/kunal/Pictures/NCL_Scripts/plot/wind.nc","r")

;---Read in zonal [u] and meridional [v] winds
   u = a->U(0,:,:)
   v = a->V(0,:,:)


;---Create plot
  wks_type = "pdf"
  wks_type at wkPaperSize = "A4"
  wks = gsn_open_wks(wks_type, "wind")

  cmap = read_colormap_file("BlAqGrYeOrReVi200")

  res                                  = True
  res at vcMinFracLengthF    = 1.0                 ;-- length of min vector as
  res at vcRefMagnitudeF      = 3.0                 ;-- make vectors larger
  res at vcRefLengthF          = 0.045               ;-- ref vec length
  res at vcGlyphStyle            = "CurlyVector"       ;-- turn on curly
vectors
  res at vcMinDistanceF        = 0.01              ;-- thin out vectors
  res at tiMainString               = "DKRZ NCL Workshop: vector curly"


  plot=gsn_csm_vector(wks,u,v,res)  ; create plot


end
