This paper represents some of Dr. Graeme Mather’s final unpublished ideas and work in South Africa. Graeme passed away on 15 August 1997. On 13 January 1999, Mr. Rob Parsons, our coauthor and Graeme’s successor at CloudQuest, also passed away. We sadly miss them and their contributions, especially in the light of the challenges faced by the scientific community regarding weather modification in the new millennium.
The Northern Province Tzaneen experiment was funded by the South African Weather Bureau, (Department of Environment Affairs and Tourism), the Water Research Commission, the Department of Water Affairs and Forestry, and the Northern Province Government. The authors are grateful for the dedicated contributions by the scientific and technical personnel and the pilots of the project.
