Experimental Investigations of Ice in Supercooled Clouds. Part II: Scavenging of an Insoluble Aerosol
Publisher: American Meteorological Society
Abstract: An experimental study of aerosol scavenging by ice growing in supercooled clouds was conducted with a continuous flow cloud chamber. Techniques for detecting insoluble (latex) submicron particles in individual ice crystals ...
Experimental Investigations of Ice in Supercooled Clouds. Part 1: System Description and Growth of Ice by Vapor Deposition
Publisher: American Meteorological Society
Abstract: A continuous flow cloud chamber system was constructed for studies of microphysical and chemical processes in supercooled clouds. An important feature of the cloud chamber was the generation of the components of the ...
The Theoretical Basis for the Parameterization of Ice Crystal Habits: Growth by Vapor Deposition
Publisher: American Meteorological Society
Abstract: A theoretical analysis of surface kinetic and gas-phase diffusional effects permits the growth rates and habits of ice crystals to be specified in a self-consistent way. The analysis makes use of the fact that the difference ...
Visualizing Vapor Pressure: A Mechanical Demonstration of Liquid–Vapor Phase Equilibrium
Publisher: American Meteorological Society
Abstract: ater phase transitions are central to climate and weather. Yet it is a common experience that the principles of phase equilibrium are challenging to understand and teach. A simple mechanical analogy has been developed to ...
The Mechanism of Ice Crystal Growth and Habit Formation
Publisher: American Meteorological Society
Abstract: The formation of multiple layers of adsorbed water molecules on the basal and prism faces of ice may be responsible for the remarkable temperature dependence of all growth variables (linear growth rate, step velocity, and ...
Simulation of Cloud Microphysical and Chemical Processes Using a Multicomponent Framework. Part I: Description of the Microphysical Model
Publisher: American Meteorological Society
Abstract: A detailed microphysical and chemical cloud model has been developed to investigate the redistribution of atmospheric trace substances through cloud processes. A multicomponent categorization scheme is used to group cloud ...
Simulation of Cloud Microphysical and Chemical Processes Using a Multicomponent Framework. Part II: Microphysical Evolution of a Wintertime Orographic Cloud
Publisher: American Meteorological Society
Abstract: A detailed microphysical model is used to simulate the formation of wintertime orographic clouds in a two-dimensional domain under steady-state conditions. Mass contents and number concentrations of both liquid- and ice-phase ...
Influence of Ice Crystal Aspect Ratio on the Evolution of Ice Size Spectra during Vapor Depositional Growth
Publisher: American Meteorological Society
Abstract: The relationship among aspect ratio, initial size, and the evolution of the size spectrum is explored for ice crystals growing by vapor deposition. Ice crystal evolution is modeled based on the growth of spheroids, and the ...
