Modeling Supersaturation and Subgrid-Scale Mixing with Two-Moment Bulk Warm Microphysics (2008, methodology): “These processes include the following: (i) the activation of cloud droplets on cloud condensation nuclei (CCN) at cloud base; (ii) condensation onto droplets above the cloud base; (iii) changes of cloud droplet spectra due to entrainment and mixing; (iv) additional activation of cloud droplets above”
Formulation of the Dutch Atmospheric Large-Eddy Simulation (DALES) and overview of its applications (2010, background): “7l )3 , (66) andkau= 10.58×109 m3 kg−2 s−1 (Pinsky and Khain, 2002, SB06) andxc is the mean mass of the cloud droplet distribution. νc is parametrized according toGeoffroy et al.(2010): νc = 1580ρqc−0.28, (67) Geosci.”
Representation of microphysical processes in cloud‐resolving models: Spectral (bin) microphysics versus bulk parameterization (2015, methodology): “Since SBM schemes calculate CCN size distributions and supersaturation at each grid point, they describe processes of in-cloud nucleation leading to the formation of small droplets at significant heights above cloud base [Pinsky and Khain, 2002; Khain et al., 2012].”
Spectral (Bin) microphysics coupled with a Mesoscale Model (MM5). Part I: Model description and first results (2005, background): “To take into account the effect of turbulence on drop– drop collision, the collision rate between droplets was increased in clouds following Pinsky and Khain (2002).”
Aerosol Effects on Intensity of Landfalling Hurricanes as Seen from Simulations with the WRF Model with Spectral Bin Microphysics (2010, background): “The inclusion of this process leads to the formation of bimodal droplet spectra with realistic droplet spectra dispersion (Pinsky and Khain 2002; Segal and Khain 2006; Segal et al. 2003).”
Optical properties of terrestrial clouds (2004, background): “Pinsky and Khain (2002) showed that the threshold of the occurrence of drizzle is around aef = 15 Am.”
Global observations of aerosol‐cloud‐precipitation‐climate interactions (2014, background): “Secondary nucleation can occur in convective clouds when coalescence and precipitation scavenging of the cloud drops decrease the combined surface area over which condensation can occur, and hence, S can exceed the maximum S that was reached near cloud base [Pinsky and Khain, 2002].”
Linear relation between convective cloud drop number concentration and depth for rain initiation (2012, background): “small cloud droplets aloft and also broaden the DSD [Pinsky and Khain, 2002; Fridlind et al., 2004].”
Growth of Cloud Droplets in a Turbulent Environment (2013, background): “Pinsky & Khain (2002) demonstrated that an average turbulence enhancement of 2 to 3 in the collision kernel significantly accelerates the process of rain formation.”
Droplet growth in warm turbulent clouds (2012, background): “Pinsky and Khain (2002) demonstrated that collision kernels taking into account the effect of air turbulence on the relative motion of droplets can lead to the acceleration of large droplets and raindrop formation.”
