Overlays multiple plots, created from other ARW WRF plot functions (deprecated in version 5.1.0).
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl" load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl" procedure wrf_overlay ( wks : graphic, plots [*] : graphic, res  : logical )
A plot resource. Set to True if you want to advance the frame before creating the next frame. Set to False if you do not want to advance the frame. Use False only if you plan on adding additional text/lines/symbols to the frame before advancing it.
This procedure overlays a number of graphical plots. This is typically used for idealized ARW WRF model runs.
wrf_overlay is part of a library of functions and procedures in WRFUserARW.ncl written to help users plot ARW WRF model data.
