Abstract: By melting concentric layers of ice, the size distribution and concentration of solid water-insoluble particles accumulated in hailstones were determined for three hailstorms in Colorado. It was found that in approximately ...

Abstract: Population of cloud droplets in a cloud may be decreased under some circumstances by their removal (along with other particles) by an ice crystal growing on an ice-forming nucleus. Further condensation of water vapor should ...

Abstract: Varying concentrations of different sized, solid, water-insoluble particles in rainwater and hailstones collected during thunderstorms indicate the existence of several scavenging mechanisms of micron-size particles. It ...

Abstract: Silver iodide particles deposited on vegetation may photolyse and combine with natural terpenes from tree oils to form compounds which either themselves become aerosols, or become attached to aerosol particles. In either ...

Abstract: Variable concentrations of different sized water-insoluble particles were found in bulk rainwater and single raindrops (liquid phase) and in hailstones (solid phase) collected from severe thunderstorms in the Colorado-Nebraska ...

Abstract: A field technique was developed to detect silver iodide seeding agent in snow samples. The technique consists of collecting snow during a snow storm, forming liquid drops by melting pellets made from the snow, and refreezing ...

Abstract: The size distribution of secondary particulate matter, formed from condensing vapors in meteoric trains in the meteoric evaporating zone, was calculated. The diameters of the particles were found to be approximately ...

Abstract: Silver chloride, bromide and iodide hydrosol particles were studied as freezing nuclei. Ice nucleation was enhanced through the exchange of iodine ions on the surface of solid silver iodide, using iodine monobromide. Drops ...

Abstract: Laboratory work showed that organic compounds have considerable promise as cloud-seeding agents. The following substances gave complete nucleation: phloroglucinol at ?2C, trichlorobenzene at ?12C, D(+)-Raffinose at ?14C, ...
