47 | ! ------------ |
---|
48 | ! Advection term for v velocity-component using Piacsek and Williams. |
---|
49 | ! Vertical advection at the first grid point above the surface is done with |
---|
50 | ! normal centred differences, because otherwise no information from the surface |
---|
51 | ! would be communicated upwards due to w=0 at K=nzb. |
