|
|
! FIND THE REST OF THE LIFTED PARCEL TEMPERATURES |
| 14 |
|
|
! & |
| 15 |
|
|
! COMPUTE THE PRECIPITATION EFFICIENCIES AND THE |
| 16 |
|
|
! FRACTION OF PRECIPITATION FALLING OUTSIDE OF CLOUD |
| 17 |

! & |
| 18 |
|
|
! FIND THE LEVEL OF NEUTRAL BUOYANCY |
| 19 |
|
|
! |
| 20 |
|
|
! Main differences convect3/convect4: |
| 21 |
|
|
! - icbs (input) is the first level above LCL (may differ from icb) |
| 22 |
|
|
! - many minor differences in the iterations |
| 23 |
|
|
! - condensed water not removed from tvp in convect3 |
| 24 |
|
|
! - vertical profile of buoyancy computed here (use of buoybase) |
| 25 |
|
|
! - the determination of inb is different |
| 26 |
|
|
! - no inb1, only inb in output |
