Among the studies
on PBL statistics,
Moyer and Young [1993] reported various buoyancy-flux profiles
that existed during the FIRE, where PBLs spanned pure surface-heating
to pure cloud-top-cooling forcing regimes, with a majority of
flows driven by a combination of both buoyancy sources.
LES has also been used as an alternative data source for studying
turbulent fluxes within the stratus-topped PBL.
Based on four simulated flow fields,
Moeng et al. [1992] were able to separate the contributions of
cloud-top longwave radiative cooling, entrainment,
and surface heating to the vertical distribution of
heat and moisture fluxes within a nocturnal stratus-topped PBL.
