</div><div class="gmail_default" style><br></div><div class="gmail_default" style>This should work for gridded data which is either on a rectilinear grid, and hence has coordinate arrays attached to the U and V variables, or on a curvilinear grid, in which you have two-dimensional coordinate arrays for the X and Y (or lat/lon) dimensions.</div>
<div class="gmail_default" style><br></div><div class="gmail_default" style>If you have a curvilinear grid that's over a map, then you will need to attach the 2D lat/lon arrays to your u and v variables via the special lat2d and lon2d attributes before you plot:</div>
<div class="gmail_default" style><br></div><div class="gmail_default" style><div class="gmail_default"> u@lat2d = f->lat</div><div class="gmail_default"> u@lon2d = f->lon</div><div class="gmail_default"> v@lat2d = f->lat</div>
<div class="gmail_default"> v@lon2d = f->lon</div><div class="gmail_default"><br></div><div class="gmail_default">The above code snippet will have to be changed, of course, to match whatever the lat/lon variables are called on your file.</div>
<div class="gmail_default"><br></div><div class="gmail_default">If you are not drawing wind barbs over a map, then you need to provide the 2D coordinates via the vfXArray and vfYArrays. See the "meteo_1.ncl" example at:</div>
