! Differences with convect4: |
| 12 |
! - specify plcl in input |
| 13 |
! - icbs is the first level above LCL (may differ from icb) |
| 14 |
! - in the iterations, used x(icbs) instead x(icb) |
| 15 |
! - many minor differences in the iterations |
| 16 |
! - tvp is computed in only one time |
| 17 |
! - icbs: first level above Plcl (IMIN de TLIFT) in output |
| 18 |
! - if icbs=icb, compute also tp(icb+1),tvp(icb+1) & clw(icb+1) |
