! UNDILUTE (ADIABATIC) UPDRAFT / 1st part |

! (up through ICB for convect4, up through ICB + 1 for convect3) |
| 10 |
! Calculates the lifted parcel virtual temperature at nk, the |

| 16 |
! Differences with convect4: |
| 17 |
! - specify plcl in input |
| 18 |
! - icbs is the first level above LCL (may differ from icb) |
| 19 |
! - in the iterations, used x(icbs) instead x(icb) |
| 20 |
! - many minor differences in the iterations |
| 21 |
! - tvp is computed in only one time |
| 22 |
! - icbs: first level above Plcl (IMIN de TLIFT) in output |
| 23 |
! - if icbs=icb, compute also tp(icb+1),tvp(icb+1) & clw(icb+1) |
