Emergency Cloud Seeding in Georgia, Summer, 1977
AbstractThree drought relief cloud seeding programs were conducted ~n Georgia during the summer of 1977 by on-site meteorologists who flew on specially equipped seeding aircraft. Suitable clouds, actively growing cumulus towers reaching at least the -5°C level, were seeded with ejectable silver iodide pyrotechnic flares. The seeding technique was patterned after the National Oceanic and Atmospheric Administration’s Florida Area Cumulus Experiment (FACE) in southern Florida, and followed a dynamic seedability hypothesis.
In limited evaluation of one of the three programs, a target~ontrol comparison indicated an excess of 27 percent in actual July-August precip- itation over that predicted from control area precipitation. A one tailed Student’s t test indicated less than five chances in 100 that this difference could be attributed to chance.
