<div dir="ltr">Thanks Mary! I will try these things you mention. Will let you know if I still encounter problems. And to answer your question, no, I didn't get any errors when the program ran.</div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Dec 21, 2015 at 11:56 AM, Mary Haley <span dir="ltr"><<a href="mailto:haley@ucar.edu" target="_blank">haley@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 class="gmail_default" style="font-size:small">Hi Andrew,</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">Setting "trGridType" to TriangularMesh will not work for vectors. This is currently only available for contours. We have it on our list to do this for vectors, but it could be awhile before we get to it. However, you shouldn't need this in your case. You have 2D lat/lon arrays, which you can generate vectors from without needing a triangular mesh.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">Are you getting any kind of error message when you execute this NCL script?</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">To debug this, I suggest first removing this line, since it won't work anyway:</div><div class="gmail_default" style="font-size:small">

I followed the convention for a 2 deg lat/lon grid, since NAM is on a lon2d/lat2d grid. I used gsnAddCyclic = false, declared my vfXArray and vfYArray, and used TriangularMesh for my grid, the same settings I used for plotting the vorticity, which showed up fine. I am thus stumped why the winds won't show up. Any advice is most appreciated.
