Detailed explanation-1: -Vincent Schaefer, a researcher with General Electric, is often credited with the first cloud seeding experiments in the 1940s. Much of Schaefer’s work during and after World War II centered on preventing aircraft from icing over in midair.

Detailed explanation-2: -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.

Detailed explanation-3: -While Texas uses cloud seeding to help irrigate fields for farmers, it’s more common in the West, where states like Idaho, California, Colorado, Utah and Wyoming use it to help fill up their rivers and reservoirs. Most programs use planes for cloud seeding, but some use ground-based flares.

Detailed explanation-4: -During winter, the clouds are mostly exacted with western disturbances. The widespread fog occurs after the passage of western disturbances. Generally, the moisture in the air is too less during winter in northern India, which limits the scope of cloud seeding.
