The Role of Entrainment in the Diurnal Cycle of Continental Convection (2010, methodology): “The Neggers et al. (2002) approach proposed for shallow convection might also be applied to congestus and deep convection, but only if one relaxes the assumption of a constant eddy turnover time.”
A Dual Mass Flux Framework for Boundary Layer Convection. Part I: Transport (2009, methodology): “As opposed to constant or case-specific lateral entrainment rates we choose to use the parameterization proposed by Neggers et al. (2002). They derived lateral entrainment rates from the simplified steady-state budget of φui, wui ∂φui ∂ z φui φ τε (24)”
A Combined Eddy-Diffusivity Mass-Flux Approach for the Convective Boundary Layer (2007, background): “An interesting alternative has been proposed by Cheinet (2003) and is a combination of the present formulation (16) and a formulation that has been proposed in Neggers et al. (2002) max 1 wu , c z , 25 where represents the eddy turnover time.”

A mass-flux cumulus parameterization scheme for large-scale models: description and test with observations (2012, background): “…are commonly specified by certain hypothesis such as constant, a designated function of altitude (e.g., Tiedtke 1989), a velocity-dependent rate (Neggers et al. 2002), an inverse-height relationship (Jakob and Siebesma 2003; Zhang 2009), a function with parcel buoyancy and inversely as the…”
A Mass-Flux Scheme View of a High-Resolution Simulation of a Transition from Shallow to Deep Cumulus Convection (2006, background): “base, while narrow, were sufficient to explain the variability in the cumulus clouds (Neggers et al. 2002), implying no role for the cloud sizes.”
Influence of the subcloud layer on the development of a deep convective ensemble (2012, background): “Some plume models can account for a positive feedback between a stronger thermodynamic excess and a reduced entrainment rate, for example by making the entrainment rate depend on vertical velocity (which in itself depends on buoyancy; e.g., Neggers et al. 2002).”
