Upshear and Downshear Evolution of Cloud Structure and Spectral Properties
Publisher: American Meteorological Society
Abstract: A dynamical model, in conjunction with a microphysical model designed to predict evolution of cloud droplet spectra, is employed to perform two-dimensional simulations of a small nonprecipitating cumulus cloud in the ...
Microscopic Approach to Cloud Droplet Growth by Condensation. Part I: Model Description and Results without Turbulence
Publisher: American Meteorological Society
Abstract: Recent observations have shown that even in adiabatic cloud cores, the cloud droplet size distributions are broader than what is expected if all droplets were exposed to the same supersaturation. This suggests the existence ...
Microscopic Approach to Cloud Droplet Growth by Condensation. Part II: Turbulence, Clustering, and Condensational Growth
Publisher: American Meteorological Society
Abstract: The goal of this work is to answer the question of whether nonuniformity in the spatial distribution of sizes and positions of cloud droplets and/or variable vertical velocity in a turbulent medium can contribute to the ...
Effects of Turbulence on Upper-Tropospheric Ice Supersaturation
