! On input: |
| 76 |
|
| 77 |
! t: Array of absolute temperature (K) of dimension KLEV, with first |
| 78 |
! index corresponding to lowest model level. Note that this array |

| 81 |
|
| 82 |
! q: Array of specific humidity (gm/gm) of dimension KLEV, with first |
| 83 |
! index corresponding to lowest model level. Must be defined |
| 84 |
! at same grid levels as T. Note that this array will be altered |
| 85 |
! if dry convective adjustment occurs and if IPBL is not equal to 0. |
| 86 |
|
| 87 |
! qs: Array of saturation specific humidity of dimension KLEV, with first |
| 88 |
! index corresponding to lowest model level. Must be defined |

! u: Array of zonal wind velocity (m/s) of dimension KLEV, witth first |
| 93 |
! index corresponding with the lowest model level. Defined at |
| 94 |
! same levels as T. Note that this array will be altered if |
| 95 |
! dry convective adjustment occurs and if IPBL is not equal to 0. |

| 117 |
! VALUE INTERPRETATION |
| 118 |
! ----- -------------- |
| 119 |
! 0 Moist convection occurs. |
| 120 |
! 1 Moist convection occurs, but a CFL condition |
| 121 |
! on the subsidence warming is violated. This |
| 122 |
! does not cause the scheme to terminate. |
| 123 |
! 2 Moist convection, but no precip because ep(inb) lt 0.0001 |
| 124 |
! 3 No moist convection because new cbmf is 0 and old cbmf is 0. |
| 125 |
! 4 No moist convection; atmosphere is not |
| 126 |
! unstable |
| 127 |
! 6 No moist convection because ihmin le minorig. |
| 128 |
! 7 No moist convection because unreasonable |
| 129 |
! parcel level temperature or specific humidity. |
| 130 |
! 8 No moist convection: lifted condensation |
| 131 |
! level is above the 200 mb level. |
| 132 |

| 133 |
! then the level NL-1. |

| 163 |
