Dear ncl-talk members,
I am having trouble producing the pennants on the wind barbs with the correct orientation for the southern hemisphere.
Here is the relevant part of my code:
; --- Create background skew-T and plot sounding----------------
vcres = True ; plot mods desired
vcres@vcGlyphStyle<mailto:vcres@vcGlyphStyle> = "WindBarb"
vcres@vcWindBarbTickAngleF<mailto:vcres@vcWindBarbTickAngleF> = -62. ;Southern Hemisphere wind barbs
skewtOpts = True
;skewtOpts@DrawColAreaFill = True ; default is False
skewtOpts@DrawColAreaFill<mailto:skewtOpts@DrawColAreaFill> = False ; default is False
;skewtOpts@tiMainString = "Cluster Average Soundings"
skewtOpts@tiMainString<mailto:skewtOpts@tiMainString> = ""
skewtOpts@DrawFahrenheit<mailto:skewtOpts@DrawFahrenheit> = False
skewtOpts@PrintZ<mailto:skewtOpts@PrintZ> = True
skewtOpts@vcGlyphStyle<mailto:skewtOpts@vcGlyphStyle> = "WindBarb"
skewtOpts@vcWindBarbTickAngleF<mailto:skewtOpts@vcWindBarbTickAngleF> = -62.
skewt_bkgd = skewT_BackGround (wks, skewtOpts)
draw (skewt_bkgd)
dataOpts = True ; options describing data and ploting
dataOpts@DrawFahrenheit<mailto:dataOpts@DrawFahrenheit> = False ; default is True
dataOpts@PrintZ<mailto:dataOpts@PrintZ> = True ; do not print Z
dataOpts@ThermoInfo<mailto:dataOpts@ThermoInfo> = False ; print thermodynamic info
dataOpts@vcGlyphStyle<mailto:dataOpts@vcGlyphStyle> = "CurlyVector"
dataOpts@vcWindBarbTickAngleF<mailto:dataOpts@vcWindBarbTickAngleF> = -62.
As you can see, I have tried setting the vcWindBarbTickAngleF = -62.0 which is correct for the southern hemisphere. No matter which variable I associate this attribute with, nothing happens. The wind barbs stay in the northern hemisphere orientation.
Can anyone help me? I have only used ncl to produce skew t plots, so I may have missed something obvious.
Cheers,
Justin
