Droplet growth in warm turbulent clouds (2012, background): “Only recently have higher-resolution (∼20 cm) measurements been possible: Siebert et al. (2010a) measured ε ∼ 1 cm2 s−3 in stratocumulus and Siebert et al. (2006a) measured ε ∼ 10 cm2 s−3 in small cumulus clouds.”
The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part 2. Simulations with gravitational effects (2015, background): “owth. It is unclear, however, the extent to which particle collision rates are aected by changes in Reynolds number at conditions representative of those in cumulus clouds (which have R ˘10;000, seeSiebert et al. 2006).Sundaram & Collins(1997) showed that particle collision rates depend on both ”
Representation of microphysical processes in cloud‐resolving models: Spectral (bin) microphysics versus bulk parameterization (2015, background): “The role of turbulent mixing and its effects remains poorly understood, despite a great deal of research effort [Paluch, 1979; Siebert et al., 2006; Burnet and Brenguier, 2007; Andrejczuk et al., 2009; Lehmann et al., 2009; Jarecka et al., 2013; Magaritz-Ronen et al., 2014; Korolev et al., 2013b].”
Growth of Cloud Droplets in a Turbulent Environment (2013, methodology): “These measurements documented that the structure of the velocity field inside studied clouds (shallow cumulus in Siebert et al. 2006a and stratocumulus in Siebert et al. 2010; mean dissipation rates of 10−3 and 10−4 m2 s−3, respectively) was close to the homogeneous isotropic high–Reynolds number…”
A Method for Estimating the Turbulent Kinetic Energy Dissipation Rate from a Vertically Pointing Doppler Lidar, and Independent Evaluation from Balloon-Borne In Situ Measurements (2010, unknown): “The range of values found for ǫ agree well with the wide range of dissipation rates measured by Chen (1975); Siebert et al. (2005) .”
