<div dir="ltr"><div><div>I have a script that I run in real-time to generate NAM forecast output at various pressure levels and plot variables. Attached is my script. I also attached a plot of the 500 mb heights/vorticity from the program.<br><br></div>For some reason, I cannot get the u and v winds to plot, meaning the wind barbs will not show up on the plot. 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. Sorry for the long ncl code. <br><br></div>Thanks,<br><br><div><div><div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div>Andrew Kren, PhD<br>
