Re: how to modify the code for using wrf output

You already have the vertical velocity (w, not omega).
At each grid point, you have or can calculate the pressure levels
(bottom_top_stag) ... call it p(Time,bottom_top_stag,south_north,west_east)

You can not use the {...} syntax because the grid is curvilinear and not
rectilinear, You must use standard indexing.

    t = 5
    n = (/32, 73/) ; lat index values of the points you want
    m = (/52, 105/) ; lon

    x = w(t,:,n,m)
    p = p(t,:,n,m)

    plt = gsn_csm_xy (wks,x,p,resxy)
