<p style="margin-top:0; margin-bottom:0">I'm using NCL 6.3.0, just noticed there was an issue for the
<span>Wind Barbs cross equator that gsn_csm_vector </span>does not currently automatically change the wind barb tick position to account for the <span>conventional difference for north and south of the equator</span>.
<br>

<p style="margin-top:0; margin-bottom:0"><br>
</p>
<p style="margin-top:0; margin-bottom:0">I knew it could <span>manually change the resource vcWindBarbTickAngleF to a negative value to get wind barbs that conform to the southern hemisphere convention</span>, but <span>this does not help for plots that cross
the equator where both conventions are needed. Please see the attachment for the example.</span></p>

<p style="margin-top:0; margin-bottom:0"><span>Here are my settings for the Wind Barbs</span></p>

<p style="margin-top:0; margin-bottom:0"><span></span></p>
<div> opts@gsnLeftStringFontHeightF = 0<br>
opts@gsnRightStringFontHeightF = 0<br>
opts@vcRefMagnitudeF = 10.0 ; define vector ref mag<br>
opts@vcRefLengthF = 0.030 ; define length of vec ref<br>
opts@vcGlyphStyle = "WindBarb" ; select wind barbs<br>
opts@vcMinDistanceF = 0.02 ; thin out windbarbs<br>
opts@vcVectorDrawOrder = "PostDraw"<br>
opts@vcRefAnnoOrthogonalPosF = -1.08</div>
