;-- open file and read variables
  f    =  addfile(diri+fili, "r")
  u    =  f->u10(0,:,:)              ;-- first time step

;-- define the workstation (graphic will be written to a file)
  wks =  gsn_open_wks("png","plot_vector_default")

;-- draw the vectors
  plot = gsn_csm_vector_map_ce(wks,u,v,False)
