| 24 | ! Description: |
|---|
| 25 | ! ------------ |
|---|
| 26 | ! Advection term for scalar variables using the Piacsek and Williams scheme |
|---|
| 27 | ! (form C3). Contrary to PW itself, for reasons of accuracy their scheme is |
|---|
| 28 | ! slightly modified as follows: the values of those scalars that are used for |
|---|
| 29 | ! the computation of the flux divergence are reduced by the value of the |
|---|
| 30 | ! relevant scalar at the location where the difference is computed (sk(k,j,i)). |
|---|
| 31 | ! NOTE: at the first grid point above the surface computation still takes place! |
