On the Growth of Layers of Nonprecipitating Cumulus Convection (2007, background): “…sources such as radiation are active, then the linearity constraint of quasi steadiness applies to the sum of the radiative and turbulent fluxes. cipitation, or sedimentation, fluxes appear to reduce the entrainment rate (e.g., Stevens et al. 1998; Ackerman et al. 2004; Bretherton et al. 2007).”
Controls on precipitation and cloudiness in simulations of trade‐wind cumulus as observed during RICO (2011, background): “Less cloud-top entrainment is associated with enhanced cloudtop droplet sedimentation ( Ackerman et al., 2004; Bretherton et al., 2006 ;A ckerman et al.,2009).”
Aerosol indirect effects – general circulation model intercomparison and evaluation with satellite data (2009, background): “On the other hand, enhanced entrainment of dry air at cloud tops or increased below-cloud evaporation of smaller precipitation drops for clouds with more and smaller cloud droplets has been demonstrated by large-eddy simulations or conceptual models to potentially lead to a decrease in L (Ackerman e”
Formulation of the Dutch Atmospheric Large-Eddy Simulation (DALES) and overview of its applications (2010, neutral): “The cloud droplet sedimentation process has an impact on cloud evolution by reducing entrainment at stratocumulus cloud top (Ackerman et al., 2004; Bretherton et al., 2007).”
Modeling Aerosol Impacts on Convective Storms in Different Environments (2009, background): “However, several situations have been studied in which this is not the case (Jiang et al. 2002; Ackerman et al. 2004; Lu and Seinfeld 2005).”
Constraining the aerosol influence on cloud liquid water path (2018, methodology): “Phys., 19, 5331–5347, 2019 black line), supports the model-based results of Ackerman et al. (2004), Xue and Feingold (2006) and Xue et al. (2008), where increasing the Nd can result in a LWP reduction in clouds in which precipitation does not reach the surface.”
Efficacy of climate forcings (2005, background): “Cloud-resolving models [Ackerman et al., 2004] suggest that the increase of cloud water content due to aerosols may be less than portrayed in global models that yield large aerosol indirect effects, which would reduce AIECldAlb but not necessarily AIECldCvr.”
Understanding macrophysical outcomes of microphysical choices in simulations of shallow cumulus convection (2008, background): “…Kogan 2000; Seifert and Beheng 2001; Morrisson and Grabowski 2007, among others), and the use of large-eddy simulation to study aerosol-cloud interactions from the perspective of climate (e.g., Kogan et al. 1995; Stevens et al. 1998; Jiang and Cotton 2000; Ackerman et al. 2004; Xue et al. 2008).”
Cloud droplet sedimentation, entrainment efficiency, and subtropical stratocumulus albedo (2007, background): “Since we depends directly on the droplet concentration through wsed, this entrainment closure can reproduce Ackerman et al.’s [2004] key result that enhanced aerosol can cause thinning of a nondrizzling stratocumulus layer capped by a dry free troposphere.”
Moisture and dynamical interactions maintaining decoupled Arctic mixed-phase stratocumulus in the presence of a humidity inversion (2011, background): “For example, in subtropical boundary layers, sedimentation removes water near cloud top resulting in less entrainment of dry, warm air and a more persistent cloud (Ackerman et al., 2004; Bretherton et al., 2007).”
