|---|
| 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! |
