Abstract

FACE-2 was a confirmatory weather modification experiment conducted in south Florida in the three summers of 1978, 1979 and 1980. The results of the FACE-2 replicated and pre-specified confirmatory rainfall analyses are presented and discussed in this paper. These results are interpreted in terms of the published criteria for confirmation of the FACE-1 rainfall results. FACE-2 did not confirm the results of FACE-1, although there are indications that seeding did increase the rainfall over the FACE target area. Some explanations for the lack of confirmation are suggested.
