25. wrfv34ptop25z10damp1 3.4 1 0.01 10 Diffusive Damping over 10km layer with top at 25 mb
36. wrfv34ptop25z10damp3 3.4 3 0.2 10 Rayleigh Damping over 10km layer with top at 25 mb
47. wrfv34ptop25z10damp3coef0p5 3.4 3 0.5 10 Rayleigh Damping over 10km layer with top at 25 mb
58. wrfv34ptop25z10damp3kz47 3.4 3 0.2 10 9 more levels in verticals to give 10 in damping layer using Rayleigh Damping over 10km layer with top at 25 mb
69. wrfv34ptop25z10damp3kz47coef0p1 3.4 3 0.1 10 9 more levels in verticals to give 10 in damping layer using Rayleigh Damping over 10km layer with top at 25 mb and a damping coefficient of 0.1
710. wrfv34ptop25z7damp3kz47 3.4 3 0.2 7 9 more levels in verticals to give 10 in damping layer using Rayleigh Damping over 7km layer with top at 25 mb
1011. wrfv34ptop50z7damp3kz38 3.4 3 0.2 7 Rayleigh Damping with 38 levels, but with 7 in the upper damping layer, ptop at 50 mb
This shows the distribution of the vertical levels.
1312. wrfv34ptop50z7damp3kz38t8b4 3.4 3 0.2 7 Rayleigh Damping with 38 levels, but with 7 in the upper damping layer, ptop at 50 mb, 8 layers 1-km deep at top, 4 levels at bottom same as std
This shows the distribution of the vertical levels.
1113. wrfv34ptop50z7damp3kz38t10b5 3.4 3 0.2 7 Rayleigh Damping with 38 levels, but with 7 in the upper damping layer, ptop at 50 mb, 10 layers 1-km deep at top, 5 levels at bottom same as std
This shows the distribution of the vertical levels.
1214. wrfv34ptop50z7damp3kz38t14b3 3.4 3 0.2 7 Smooth depth transitions.
Rayleigh Damping with 38 levels, but with 7 in the upper damping layer, ptop at 50 mb, 14 layers 1-km deep at top, 3 levels at bottom same as std
This shows the distribution of the vertical levels.
