Abstract: This study is based on the radar-evaluated rainfall data from 52 south Florida cumulus clouds, 26 seeded and 26 control clouds, selected by a randomization procedure. The fourth root of the rainfall for both seeded and ...

Abstract: In the summer of 1965, a series of tropical cumulus cloud experiments was carried out by Project Stormfury, a joint program of the U. S. Navy and Environmental Science Services Administration. Of twelve clouds seeded with ...

Abstract: The scientific and technological aspects of weather modification are addressed, emphasizing the need for physical understanding, sequential development, predictor variables and an interdisciplinary approach. The experience ...

Abstract: Downdrafts are postulated as a primary linkage dynamically seeded invigorated cloud towers and those events near and below cloud bases which cause enhanced inflow, new tower growth leading to cloud expansion, and frequent ...

Abstract: A one-dimensional numerical cumulus model was tested against data from a randomized seeding experiment made in South Florida in 1968. Fourteen GO clouds were studied. Nine were seeded by pyrotechnics with 1 kg of silver ...

Abstract: This paper presents a model of the growth of cumulus clouds. The water content and maximum height of rising towers are calculated using a buoyancy equation with consideration of effects of entrainment and water load. The ...
