    ! ARGUMENTS

    ! On input:

    ! t: Array of absolute temperature (K) of dimension KLEV, with first
    ! index corresponding to lowest model level. Note that this array
    ! will be altered by the subroutine if dry convective adjustment
    ! occurs and if IPBL is not equal to 0.

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

    ! qs: Array of saturation specific humidity of dimension KLEV, with first
    ! index corresponding to lowest model level. Must be defined
    ! at same grid levels as T. Note that this array will be altered
    ! if dry convective adjustment occurs and if IPBL is not equal to 0.

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

    ! v: Same as u but for meridional velocity.

    ! p: Array of pressure (mb) of dimension KLEV, with first
    ! index corresponding to lowest model level. Must be defined
    ! at same grid levels as T.

    ! ph: Array of pressure (mb) of dimension KLEV + 1, with first index
    ! corresponding to lowest level. These pressures are defined at
    ! levels intermediate between those of P, T, Q and QS. The first
    ! value of PH should be greater than (i.e. at a lower level than)
    ! the first value of the array P.

    ! nl: The maximum number of levels to which convection can penetrate, plus 1
    ! NL MUST be less than or equal to KLEV-1.

    ! delt: The model time step (sec) between calls to CONVECT

    ! On Output:

    ! iflag: An output integer whose value denotes the following:
    ! VALUE INTERPRETATION
    ! ----- --------------
    ! 0 Moist convection occurs.
    ! 1 Moist convection occurs, but a CFL condition
    ! on the subsidence warming is violated. This
    ! does not cause the scheme to terminate.
    ! 2 Moist convection, but no precip because ep(inb) lt 0.0001
    ! 3 No moist convection because new cbmf is 0 and old cbmf is 0.
    ! 4 No moist convection; atmosphere is not
    ! unstable
    ! 6 No moist convection because ihmin le minorig.
    ! 7 No moist convection because unreasonable
    ! parcel level temperature or specific humidity.
    ! 8 No moist convection: lifted condensation
    ! level is above the 200 mb level.
    ! 9 No moist convection: cloud base is higher
    ! then the level NL-1.

    ! ft: Array of temperature tendency (K/s) of dimension KLEV, defined at same
    ! grid levels as T, Q, QS and P.

    ! fq: Array of specific humidity tendencies ((gm/gm)/s) of dimension KLEV,
    ! defined at same grid levels as T, Q, QS and P.

    ! fu: Array of forcing of zonal velocity (m/s^2) of dimension KLEV,
    ! defined at same grid levels as T.

    ! fv: Same as FU, but for forcing of meridional velocity.

    ! precip: Scalar convective precipitation rate (mm/day).

    ! VPrecip: Vertical profile of convective precipitation (kg/m2/s).

    ! wd: A convective downdraft velocity scale. For use in surface
    ! flux parameterizations. See convect.ps file for details.

    ! For use in surface flux parameterizations. See convect.ps
    ! file for details.

    ! perturbation scale (gm/gm).
    ! For use in surface flux parameterizations. See convect.ps
    ! file for details.

    ! cbmf: The cloud base mass flux ((kg/m**2)/s). THIS SCALAR VALUE MUST
    ! BE STORED BY THE CALLING PROGRAM AND RETURNED TO CONVECT AT
    ! ITS NEXT CALL. That is, the value of CBMF must be "remembered"
    ! by the calling program between calls to CONVECT.

    ! det: Array of detrainment mass flux of dimension KLEV.
