And China's lavish programme is likely to receive even more money; the country has listed weather modification as one of the key projects in its eleventh five-year plan, and says it will introduce the latest equipment for both research and operations.
It is not surprising that European American settlers in the Great Plains, dependent on agriculture and plagued by drought, would develop an interest in rainmaking. The earliest attempts involved the concussion method, which was premised on the theory that gunpowder explosions triggered friction and generated nuclei to produce rain.
James Pollard Espy (or the Storm King) (May 9 1785 – January 24 1860) was a U.S. meteorologist. Espy developed a convection theory of storms, explaining it in 1836 before the American Philosophical Society and in 1840 before the French Académie des Sciences and the British Royal Society.
The cereal manufacturer, C. W. Post of Texas, maintained belief in the concussion method. From 1911 to 1914, Post executed “rain battles” near Post City, Texas, detonating dynamite along the Caprock Escarpment. Inspired by an occasional rain fall, Post optimistically predicted that rainmaking would one day replace irrigation.
Vincent Schaefer (1906–1993) discovered the principle of cloud seeding in July 1946 through a series of serendipitous events. Following ideas generated between himself and Nobel laureate Irving Langmuir while climbing Mt. Washington in New Hampshire, Schaefer, Langmuir’s research associate, created a way of experimenting with supercooled clouds using a deep freeze unit of potential agents to stimulate ice crystal growth
