| dc.description.abstract | A description is given of a program of randomized seeding of orographic cumuli over southeastern Arizona. This investigation, started in 1957, is still in progress. The aims have been to learn more about natural cloud processes and to ascertain if airborne silver iodide seedings can modify them. It will be shown that analyses of cloud photographs, radar observations, lightning observations and rainfall data suggest that cloud seeding modified the natural cloud processes. However, the changes observed so far have not been large enough to conclude that effects have positively been established. | |
| dc.description.sponsorship | The major support for the research discussed in this report was supplied by the National Science Foundation under Grants NSF-G4175 and NSF-G5607 and the State of Arizona. The Geophysical Research Directorate of the Air Force Cambridge Research Center under Contract AF 19(604)-1134 and the U. S. Forest Service under Contract Number 12-11-332-58 also contributed materially to the research. The U. S. Weather Bureau played a major role in this research through the loan of equipment and through the efforts of the Tucson office in making observations readily available at all times. | |
