Re: Error in wrf_Surface1.ncl

Vanesa,

I think the problem is that because PanelPlot is set to True, this causes none of the contour and vector plots to be removed when you call wrf_map_overlays. Thus, when you call wrf_map_overlays again, it's telling you that "vector" (in this case) has already been overlaid on a plot and can't be overlaid again.

Try calling wrf_vector again, but with a different variable on the left side, and overlay this instead. For example:

      vector1 = wrf_vector(a,wks,u10,v10,opts)
      vector2 = wrf_vector(a,wks,u10,v10,opts)

      delete(opts)

    ; MAKE PLOTS
      plot = wrf_map_overlays(a,wks,(/contour_tc,contour_psl,vector1/),pltres,mpres)
      draw(plot)
      draw_shapefile_lines(wks,plot)
      frame(wks)
      plot = wrf_map_overlays(a,wks,(/contour_td,vector2/),pltres,mpres)
      draw(plot)
      draw_shapefile_lines(wks,plot)
      frame(wks)
