| 22 | ! Advection term for w velocity-component using Piacsek and Williams. |
|---|
| 23 | ! Vertical advection at the first grid point above the surface is done with |
|---|
| 24 | ! normal centred differences, because otherwise no information from the surface |
|---|
| 25 | ! would be communicated upwards due to w=0 at k=nzb. |
