Detailed explanation-1: -In India, cloud seeding operations were conducted during the years 1983, 1984–87, 1993-94 by Tamil Nadu Govt due to severe drought. In the years 2003 and 2004 Karnataka government initiated cloud seeding. Cloud seeding operations were also conducted in the same year through US-based Weather Modification Inc.

Detailed explanation-2: -In 1946, Schaefer conducted the first true cloud seeding experiment by aircraft. He dropped 6 pounds of crushed dry ice into a cloud in the Adirondack Mountains of New York. Almost immediately, snow began to fall.

Detailed explanation-3: -Cloud seeding is the process of spreading either dry ice or more commonly, silver iodide aerosols, into the upper part of clouds to try to stimulate the precipitation process and form rain. Cloud seeding uses planes to spray clouds with chemicals to condense smaller particles into larger rain droplets.

Detailed explanation-4: -Cloud seeding is perhaps the ultimate silver bullet, in which literal silver in the form of silver iodide is infused into clouds, causing ice crystals to form and water to condense into rain or snow. Cloud seeding is a form of planned weather modification.
