The problem is that the u and v are on different lat/lon points so the
IDV needs to resample the v to the u points.  To do that, you need to
have more than one level selected.  By default, the IDV only selects
the first level for plan views to avoid a lot of data downloading.
You can select 2 or more levels from the Levels subset tab or select
All levels.  If you are going to look at several levels, I would suggest
the latter.  However, be aware that you will have to download a lot
of data for all the timesteps/levels.
