Hi Soo-Jin,

You can use the "overlay" procedure to overlay an additional contour
plot. The data for the contour plot must have coordinate arrays in
the same data space as your vector/scalar plot.

Here's an example:

   cnres = True ; Set up resource list for contours
   cnres@... = ...

   do imod = 0, dimsizes(mNames)-1

    plot (imod) = gsn_csm_vector_scalar_map(wks,u850,v850, skew,res)
    contour = gsn_csm_contour(wks,data,cnres)
    overlay(plot(imod),contour)

   end do ; imod-end

You can see some contour on contour overlay examples at:
