Hi Merrill,
Thanks for providing your scripts and data offline.
The issue is that the text associated with wrf_vector is drawn using gsn_text_ndc, and hence it is *not* attached to the "vector" plot.
When you overlay "vector" on "map", then, the titles are long gone.
You are doing the right thing using gsn_text_ndc to add the text yourself.
You can also use gsn_create_text and gsn_add_annotation to attach the text to the top left of the plot. This way, if you need to resize the plot, the text will stay with it.
Finally, I converted your code to use gsn_csm_vector instead of wrf_vector, although this is not absolutely necessary. I did notice that this slightly changes the number of wind barbs that you get.
See the attached modified version of your script, and one of the resultant PNG images.
