    Andres,

    Just to make sure, you have set gsnDraw = False in the vector/scalar resources,
    right? Assuming you have, you might try setting cnFillDrawOrder = "PreDraw"
    under the shaded topography resources. (Or, you can set cnLineDrawOrder =
    "PostDraw" and vcVectorDrawOrder = "PostDraw" under the vector/scalar
    resources.)

    The other option I would try would be to manually shade the topography using
    cnFillColors, and draw the topography with the vector field using
    gsn_csm_vector_scalar_map_polar. Then I would draw the scalar field with
    gsn_csm_contour and overlay....

    Let us know if neither of these work...
