Osborn, USDA, Chairman'~ <br />Curtis W. Bowser, USBR <br />Olin H. Foehner, USBR <br />David P.

Mordy, Center for the Study of Democratic Institutions <br /> <br /> <br />and the Center for the Future, Santa Barbara, California, presented a paper <br /> <br />at the IUGG general assembly in France in August, 1974, summarizing weather <br />modification efforts from 1971 through 1974. His summary of current <br />research efforts in weather modification is as follows: <br /> <br />"Current weather modification research is aimed at hazard <br />mitigation, precipitation modifications, and the understanding of <br />inadvertent weather and climate changes. Much of it in the <br />United States in the 1970's has been concentrated on five major <br />efforts, with the following objectives: (1) to determine weather <br />hailstorms can be modified to suppress hail damage in the high <br />plains of the United States (National Hail Research Experiment, <br />directed by the National Center for Atmospheric Research and <br />sponsored by the National Science Foundation); (2) to determine <br />whether the maximum wind speeds in tropical'cyclones (hurricanes) <br />can be modified by cloud seeding and thus reduce the damage <br />potential (Project Stormfury, sponsored by the U.S. Department of <br />Commerce, NOAA); (3) to determine whether practical benefits from <br />increased precipitation or snowfall displacement can be secured <br />with existing weather modification technology or by development of <br />improved technolo9Y (Project Skywater, sponsored b~ the U.S. <br />Department of Interior, Bureau of Reclamation); (4) to determine <br />whether mesoscale precipitation bands entering the West Coast can <br />be seeded to produce substantial increases in precipitation <br />(Santa Barbara Project, sponsored by the U.S. Navy and National <br />Science Foundation); and (5) to determine the reality, extent, and <br />causes of the reported precipitation anamoly produced by the city <br />of St. Louis (Metromex, sponsored by the National S~ience Foundation)." <br /> <br />, <br />
