  ! --- ARGUMENTS
  ! -------------------------------------------------------------------
  ! --- On input:

  ! t:   Array of absolute temperature (K) of dimension ND, 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 ND, 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 ND, 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 ND, 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.

  ! tra: Array of passive tracer mixing ratio, of dimensions (ND,NTRA),
  ! where NTRA is the number of different tracers. If no
  ! convective tracer transport is needed, define a dummy
  ! input array of dimension (ND,1). Tracers are defined at
  ! same vertical levels as T. Note that this array will be altered
  ! if dry convective adjustment occurs and if IPBL is not equal to 0.

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

  ! ph:  Array of pressure (mb) of dimension ND+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 ND-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 ND, defined at
  ! same
  ! grid levels as T, Q, QS and P.

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

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

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

  ! ftra: Array of forcing of tracer content, in tracer mixing ratio per
  ! second, defined at same levels as T. Dimensioned (ND,NTRA).

  ! 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.

  ! tprime: A convective downdraft temperature perturbation scale (K).
  ! For use in surface flux parameterizations. See convect.ps
  ! file for details.

  ! qprime: A convective downdraft specific humidity
  ! 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 ND.
