If you have a 3D wind field and a geopotential field, you can select
the flow vectors derived parameter and then you should see a Display
option for Streamlines over topography.  When you select that you 
will be prompted for the topography field and at that point you can 
select the 3D geopotential height.  I'm not sure if that's what
you have in mind, but it's one option.  You'll probably want to 
exaggerate the vertical scale.

If you have a 2D surface field, you could do the same thing if you
have a topography field.
