A New Parameterization for Shallow Cumulus Convection and Its Application to Marine Subtropical Cloud-Topped Boundary Layers. Part I: Description and 1D Results (2004, methodology): “As the nature of the turbulence is very different in a dry convective subcloud layer and in a cumulus layer, the use of two different parameterizations to represent the turbulent transports in these two layers is a sensible choice, though a unified scheme (e.g., Lappen and Randall 2001 ) is also ap”
A Dual Mass Flux Framework for Boundary Layer Convection. Part I: Transport (2009, methodology): “This motivates parameterizing both PBL cloudiness and transport in terms of the same reconstructed joint-distribution, an approach demonstrated by Lappen and Randall (2001) and Golaz (2002) to enable a unified, integrated representation of subgrid transport and clouds for different regimes.”
The Cumulus Parameterization Problem: Past, Present, and Future (2004, background): “[For relations between the basic closures in mass-flux models and those in higher-order turbulence closure models, see Lappen and Randall (2001a–c).] c. Nondiagnostic and nondeterministic nature of cumulus mass flux In a model with a relatively coarse horizontal resolution, the problem of cumulus…”
An eddy‐diffusivity/mass‐flux parametrization for dry and shallow cumulus convection (2004, methodology): “The mass-flux approach was introduced in the framework of cumulus convection (Ooyama 1971; Betts 1973; Yanai et al. 1973; Arakawa and Schubert 1974; Betts 1975; Lappen and Randall 2001a ), as a result of observational evidence showing that the vertical transport is dominated by narrow cloudy updrau”
A Prognostic Parameterization for the Subgrid-Scale Variability of Water Vapor and Clouds in Large-Scale Models and Its Use to Diagnose Cloud Cover (2002, methodology): “…have shown that PBL distribution can also exhibit signiﬁcant skewness (e.g., Bougeault 1982), and therefore future development of the scheme may also incorporate the effect of nonprecipitating convection on the skewness budget, possibly using a mass ﬂux approach as in Lappen and Randall (2001).”
ATMOSPHERIC MOIST CONVECTION (2005, background): “Although some recent work has attempted to unify the representation of cloud and subcloud processes (Lappen & Randall 2001, Golaz et al. 2002a,b, Cheinet 2003, 2004), these models require a vertically resolved representation of the trade-wind layer.”
Using Probability Density Functions to Derive Consistent Closure Relationships among Higher-Order Moments (2005, methodology): “64 This differs from the mass-flux formulas of Mironov et al. (1999), Abdella and Petersen (2000), and Gryanik and Hartmann (2002), who instead propose a formula that can be derived from a triple delta function PDF.

A Combined Eddy-Diffusivity Mass-Flux Approach for the Convective Boundary Layer (2007, methodology): “Therefore, virtually all attempts to model turbulent transport in the convective boundary layer with a mass-flux approach utilize a decomposition in updrafts (w w) and downdrafts (w w) (Chatfield and Brost 1987; Randall et al. 1992; Lappen and Randall 2001a; Petersen et al. 1999; Wang and Albrecht”
