On the Analysis of a Cloud Seeding Data Set over Tasmani

An analysis of the cloud seeding activity for the period 1960-2005 is presented on a hydroelectric (objective) capture area, located in central Tasmania. The analysis was done through a double relationship in the average monthly area of precipitation in the months of May to October. The results indicate that increases in monthly precipitation are observed within the target area relative to nearby controls during periods of cloud seeding activity. The values of increase of precipitation found ranged from 5 to 14% according to the statistical results.
