Hi Lei,
You can create another array in which you put 0 for below 90% confidence and
1 for above 90% confidence. After, you can plot this array as filled
contours, without its contour, then plot above this field, the rainfall
field.
As a result, you'll have your rainfall field with shades where it is above
90% significant.
See below
mapa = True
mapa_at_gsnFrame = False
mapa_at_gsnDraw = False
mapa_at_gsnAddCyclic = False
mapa_at_cnFillOn = True ; c/ preenchimento
de cores
mapa_at_cnLinesOn = False ; s/ linhas
mapa_at_cnLineLabelsOn = False ; s/ rotulos nas
linhas
mapa_at_cnMonoFillColor = True ; uma unica cor =
sombreado
mapa_at_cnFillColor = "grey" ; cor do sombreado
mapa_at_lbLabelBarOn = False ; s/ barra de cores
plot0 = gsn_csm_contour_map_ce( wks, mask, mapa ) ; plota sombreado
mapa2 = True
mapa2_at_gsnFrame = False
mapa2_at_gsnDraw = False
mapa2_at_gsnAddCyclic = False
mapa2_at_cnFillOn = False
plot1 = gsn_csm_contour( wks, contourField, mapa2 )
overlay( plot0, plot1 )
draw( plot0 )
As you can see, plot0 is the shaded field and plot1 is the contour plot.
See, also, an attached figure showing the result of this plot.
I hope I could help you
Best regards,
Mateus
