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: Preliminary results of a chemical analysis of hailstone slice residues are reported. The radial pattern of Fe particles shows a marked outer ring of relatively high concentration. The possible causes are discussed and it ...

Abstract: A detailed analysis is made of the environmental conditions existing on each of the declared hail days during the randomized seeding experiment. From the many soundings available each day, the one most representative of ...

Abstract: Measurements of ice-forming nuclei and other components of the atmospheric aerosol (cloud condensation nuclei, Aitken nuclei, giant particles) were made at two ground stations in the operational area of a Colorado field ...
