A script for Taylor diagrams in the AMWG diagnostics package uses the pressure data for
vertical interpolation for 300-mb zonal wind, and vertical weighted average of relative humidity
and temperature. In the current script, “lev”, lev = po*(hyam+hybm), is used for pressure, but lev
is not the actual pressure at each grid point.

Thus, pressure should be computed using the NCL function, pres_hybrid_ccm, which
calculates pressure at hybrid levels [pres(i,j)=po*hyam+ps(i,j)*hybm]. Also, a variable at a
specific pressure level should be calculated by a vertical interpolation function (vinth2p) and
should not be a value at a closest pressure level.
