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! |
