I can think of two methods, depending on how you want your plot to look.
One way to do this which I "think" would work would be to create 'dummy'
2-d arrays of U and V (with appropriate lat/lon coords), with all values
set to missing except for the locations identified by you 1d lat/lon
fields; the function getind_latlon2d might be helpful in this regard

Another way of doing this would be to plot the winds using the wmbarbmap
procedure over a regular contour map
