16  ! vertmix : determines theta, t, q, qs, u and v of the mixture generated by
17  ! adiabatic mixing of air between plim1 and plim2 with weighting w.
18  ! If plim1 and plim2 fall within the same model layer, then theta, ... v
19  ! are those of that layer.
20  ! A minimum value (dpmin) is imposed upon plim1-plim2
