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