46! Description:
47! ------------
48! Advection term for scalar variables using the Piacsek and Williams scheme
49! (form C3). Contrary to PW itself, for reasons of accuracy their scheme is
50! slightly modified as follows: the values of those scalars that are used for
51! the computation of the flux divergence are reduced by the value of the
52! relevant scalar at the location where the difference is computed (sk(k,j,i)).
53! NOTE: at the first grid point above the surface computation still takes place!
