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