Santa Barbara Pyrotechnic Seeding Device Test Program 1969-70 Season and 1967-70 Summary.
Abstract
Tests of the effectiveness of ground-released pyrotechnics in enhancing precipitation have been continued for the third consecutive winter season in the mountains and valleys of Santa Barbara County. A pyrotechnic candle of the LW-83 formulation was ignited just prior to and during the passage of convection bands over the seeding site in the Santa Ynez mountains. The bands were detected upwind of the test area and tracked into the test area by use of telemetered raingages and weather radar. This year's sample consisted of 13 seeded and nine non-seeded bands bringing the three year sample to a total of 43 seeded and 42 non-seeded bands. A computerized seeding area of effect model has been developed and used to predict an envelope of seeding area of effects for the various statistical categories. (Author)
