On the Parameterization of Evaporation of Raindrops as Simulated by a One-Dimensional Rainshaft Model (2008, methodology): “To specify these functions, the collision efficiencies of Pinsky et al. (2001) are used as well as several parameterizations of coalescence and breakup (Low and List 1982; Beard and Ochs 1995; Brown 1997).”
Uncertainty assessment of current size-resolved parameterizations for below-cloud particle scavenging by rain (2010, unknown): “The raindrop-particle collection efficiency E(dp,Dp) has been investigated extensively in a series of previous studies (e.g., Wang and Pruppacher, 1977; Grover and Pruppacher, 1985; Slinn, 1983; Pruppacher and Klett, 1997; Pinsky and Khain, 2001).”
Effects of in‐cloud nucleation and turbulence on droplet spectrum formation in cumulus clouds (2002, methodology): “² The increase of the collision kernels with height, found by Pinsky et al. (2001), was taken into account.”
Aerosol impact on the dynamics and microphysics of deep convective clouds (2005, methodology): “The model uses height-dependent drop–drop and drop–graupel collision kernels calculated by means of the hydrodynamic method valid within a wide range of drop and graupel sizes (Khain et al. 2001a; Pinsky et al. 2001).”
Spectral (Bin) microphysics coupled with a Mesoscale Model (MM5). Part I: Model description and first results (2005, methodology): “The model uses height-dependent drop–drop and drop–graupel collision kernels that are calculated using a hydrodynamic method valid within a wide range of drop and graupel sizes (Khain et al. 2001b; Pinsky et al. 2001).”
PARTICLE-TURBULENCE INTERACTIONS IN ATMOSPHERIC CLOUDS (2003, unknown): “In a later study, Pinsky et al. (2001) extended this type of analysis to higher droplet Reynolds numbers to obtain collision efficiencies for droplets with radii up to 300µm.”
Droplet growth in warm turbulent clouds (2012, background): “Pinsky et al. (2001) recognized that the droplet terminal velocity can increase with height (decreasing ambient air pressure and density) and this will increase the relative motion between a pair of droplets.”
Simulation of effects of atmospheric aerosols on deep turbulent convective clouds using a spectral microphysics mixed-phase cumulus cloud model. Part I: Model description and possible applications (2004, background): “Pinsky et al. (2001) recalculated the collision efficiencies and collision kernels for drops within a wide range of sizes from 1 to 300 mm with a high resolution of 1 mm.”
Growth of Cloud Droplets in a Turbulent Environment (2013, background): “Pinsky et al. (2001) considered a different mechanism concerning the change in the droplet terminal velocity.”
