<div dir="ltr">Thanks Adam,<div><br></div><div>Is there any example for this in which I can plot the tropopause height (single line contour) on top the zonal mean wind (shading). I tried to use overlay but it seems to be complicated and the axis is not matched. Please find an example below using matlab.</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jul 16, 2015 at 11:16 PM, Adam Phillips <span dir="ltr"><<a href="mailto:asphilli@ucar.edu" target="_blank">asphilli@ucar.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div><div><div>Hi Chang,<br></div>As you likely know there are numerous height/latitude examples here: <br><a href="http://www.ncl.ucar.edu/Applications/height_lat.shtml" target="_blank">http://www.ncl.ucar.edu/Applications/height_lat.shtml</a><br><br></div>If you want to overlay a zonal mean on top of a height (Y-axis) by latitude (x-axis) plot I would recommend creating each plot separately, and then using gsn_add_annotation to add the zonal mean plot to the height/latitude plot. <br><a href="http://www.ncl.ucar.edu/Applications/annotate.shtml" target="_blank">http://www.ncl.ucar.edu/Applications/annotate.shtml</a><br><br></div>You will have to work on getting the <a href="http://www.ncl.ucar.edu/Document/Graphics/Resources/am.shtml#amJust" target="_blank"><em>amJust</em></a>,
