---|
| 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. |
