Abstract: Analysis of three cloud seeding experiments over areas of Australia suggests that results varied with cloud-top temperature; when cumulus and similar clouds had top temperatures ??10C rainfall was increased by seeding, but ...

Abstract: A cloud-seeding experiment was conducted in South Australia from 1957 to 1959 inclusive in which clouds over one of two areas were seeded with silver-iodide smoke released from an aircraft, with random choice of area. No ...

Abstract: A cloud-seeding experiment was conducted in the Snowy Mountains of Australia from 1955?1959 inclusive. The objective was to determine if silver-iodide smoke released from an aircraft into clouds could increase the precipitation ...

Abstract: Finely divided zinc sulfide and freezing nuclei in the form of silver-iodide smoke were released from separate generators at the same time from the same position on the ground. Both were detected simultaneously at distances ...

Abstract: From 1958 to 1963 an experiment was conducted in the New England region of Australia, in which clouds were seeded with silver iodide smoke released from an aircraft. Clouds over two areas were seeded, with random choice ...

Abstract: Isolated cumulus clouds with supercooled tops were seeded from an aircraft. Either a large (20 gm), small (0.2 gm) or zero quantity of silver iodide was used, with random choice of treatment. The amount of rain which fell ...

Abstract: The performance of a silver iodide smoke generator, mounted on an aircraft, was measured in flight. The ice-nucleus output was 1014 per gram of silver iodide active at ?15C and 1012 at ?10C. Considerable variations in the ...

Abstract: A cloud-seeding experiment was conducted in Tasmania using a target area and three control areas. Seeding was on a random basis using silver-iodide smoke released from an aircraft. Evidence is presented that seeding increased ...
