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