The thermodynamic equation and moisture equations, for temperature and

For QTCM1, we use a version of the Betts-Miller (1986)
moist convective adjustment scheme, with convection restoring temperature
toward convective
profile . The moisture sink and convective heating terms are given by

the
time scale of convection in strongly convecting regions and
a smoothed Heaviside function depending on
, given in square brackets, a quantity related to CAPE projected on
retained structures.
The convective profile of temperature is given as
a reference profile
independent of space, plus departures
following a moist adiabat from the
boundary layer with vertical profile of
. An additional closure
assumption is required, which links

after some
manipulation. Examples of this closure are discussed in [1]
and [],
where the dry stability
and the gross moisture stratification
are the contributions of s and q to

). The sum of these equations yields the moist static energy
equations (
) with the q terms simplified to
