overlay sparse wind vectors on a contour plot

Hi all,

I have some observations data at sparse locations. I would like to plot
the wind vectors observed at these surface stations overlaid on a
contour plot. The lat, lon, U and V are 1D arrays.
It seems that the functions gsn_csm_vectors* requires more dense data or
regular grid, or monotically lat and lon...
I tried to reorder my data: I built 2D arrays of U and V with 1D arrays
of increasing lat and lon. It does not work.
I'm sure lots of people have already done this kind of graphs.

Can you help me?

Thanks
Sophie
