Abstract

The Program for Atmospheric Water Supply (PAWS) is a randomized summer rain stimulation experiment utilizing dry ice released by Learjet as the seeding agent. Seeding is done during penetration into growing turrets of convective storms at the -10°C level. The main goal of the PAWS is to increase the water supply to all the people living in the dry climate of South Africa: but particularly to the Eastern Transvaal where rapid industrial and population growth will require additional water within the next generation. The experiment is now examining the physical effects of seeding on individual cloud systems. In the future, it is expected that statistical evaluations will be carried out over predetermined areas on the ground. The PAWS study has been on-going since 1981 and is partially described in Grosh (1988a), Dixon and Mather (1986), Morrison et el. (1986) and Mather et el. (1986), where initial radar and airborne microphysical analyses are briefly discussed. A series of lengthy annual reports supplies more complete and current information (Grosh, 1988b).
