Seeding Results Favor Small Clouds in China, South Dakota, and Yugoslavia
AbstractA comparison four cloud seeding projectson three continents of indicates that smaller clouds may give much greater percentage increases in rainfall than do larger ones in weather modification efforts. Project Cloud Catcher, randomized a single-cloud project in South Dakota1969-1970 (Denniset al., 1975) is compared here to a randomized two-area projectin Fugianprovince, China,1975, 1977,1981 (Yeh et al., 1982). Also compared are rainfall results from two non-randomized, hail suppression efforts South Dakota, in 1972-1976 (Pellett et al., 1977) and in Serbia, Yugoslavia, 1970-1979 (Curic, 1981).
