Revision 1.1 1997/08/29 08:54:20 raasch ! Initial revision ! ! ! Description: ! ------------ ! Advection term for scalar variables using the Piacsek and Williams scheme ! (form C3). Contrary to PW itself, for reasons of accuracy their scheme is ! slightly modified as follows: the values of those scalars that are used for ! the computation of the flux divergence are reduced by the value of the ! relevant scalar at the location where the difference is computed (sk(k,j,i)). ! NOTE: at the first grid point above the surface computation still takes place! !------------------------------------------------------------------------------!
