Re: confidence interval

Dear lei,

Try something like this.

;significance contours
  pres = True
  pres_at_cnFillPattern = 6
  pres_at_cnLinesOn = False
  pres_at_cnLineLabelsOn = False
  pres_at_cnLevelSelectionMode = "ManualLevels"
  pres_at_cnInfoLabelOn = False
  pres_at_cnMinLevelValF = 0.0
  pres_at_cnMaxLevelValF = 0.25
  pres_at_cnLevelSpacingF = 0.05
  pres_at_cnLineThicknessF = 2.0
  pres_at_NoHeaderFooter = True

        contour = wrf_contour(a[ifile],wks,diff(:,:),res)
        contourT = wrf_contour(a[ifile],wks,Tavg(:,:),opts)
        contoursig = wrf_contour(a[ifile],wks,prob(:,:),pres)
        contoursig = ShadeLtContour(contoursig,0.051,6)
plot=wrf_map_overlays(a[ifile],wks,(/contour,contourT,contoursig/),pltres,mpres)

It assumes a 95% confidence.
