dated February 14, 1956: Inducement of rain

The expert committee, set up by the US President in 1952 to study rain-making and weather modification, has reported that rainfall could be substantially increased through cloud-seeding. The study of cloud-seeding operation on the Pacific Coast, where it is being conducted almost on a permanent basis, has shown that it has increased water precipitation from nine to 17 per cent. Capt.

At present cloud-seeding is done by releasing into the atmosphere dry ice or silver iodide particles.
