Title:Freezing rate due to heteorogeneous nucleation
Publication:J. Atmos. Sci., 51, 1843-1856
Abstract:The heteorogeneous nucleation of ice from supercooled water is influenced by the nature of the foreign nuclei that serve as the sites for ice embryo formation, and by the stochastic nature of the process of embryo growth to criticla size. The relative roles of these two factors have been the subject of some debate, especially as they influence the way

Abstract:The oxygen 18/oxygen ($^{18}O/^{16}O$) and deuterium/hydrogen (D/H) ratios of snowmelt have been used for esimating the weighted mean temperatures in clouds where ice-phase water capture has occurred during the precipitation-forming process.

Publication:J. Atmos. Sci., 51, 2613-2630
Abstract:A detailed microphysical and chemical cloud model has been developed to investigate the redistribution of atmospheric trace subtances through cloud processes. A multicompoent categorization scheme is used to group cloud particles into different bins according to their various properties. Cloud drops are categorized simultaneously and independently in both their water mass and solute mass components.

Abstract:The results from a recently revised microphysical model are compared with airborne measurements and observations of a small cumulus. The model used was a parcel model with explicit microphysics. A gaseous tracer, sulfur hexafluoride, was used to tag a region of the cloud to help observe the behavior of the one region of the cloud.

The large-scale observations taken together with in situ measurements indicate that the most prevalent growth condition for large ice particles in active convection is sublimation during riming...

Abstract:It is important to properly simulate the extent and ice water content of tropical anvil clouds in numerical models that explicitly include cloud formation because of the significant effects that these clouds have on the radiation budget. For this reason, a commonly used bulk ice-phase microphysics parameterization was modified to more realistically simulate some of the microphysical processes that occur in tropical anvil clouds.

Step formation at crystal edges and vapor diffusion easily explain these observations.

Abstract:This two-part study attempts to find appropriate mass dimension and terminal velocity relationships that, when considered together with particle size distributions (PSD), agree with coincident measurements of ice water content (IWC), and with variables related to higher moments such as the mean mass-weighted fall speed.

Title:Refinements to Ice Particle Mass Dimensional and Terminal Velocity Relationships for Ice Clouds. Part II: Evaluation and Parameterizations of Ensemble Ice Particle Sedimentation Velocities
Publication:Journal of the Atmospheric Sciences, 64, 1068-1088.
Abstract:This two-part study addresses the development of reliable estimates of the mass and fall speed of single ice particles and ensembles. Part I of the study reports temperature-dependent coefficients for the mass-dimensional relationship
