And by now you must have understood, how significant the limitations of this technology are. Imagine if the wind is blowing from south to north in India. The rainy season moves from south to north. First, clouds form around Karnataka and Kerala. Later, these clouds reach Delhi. By using cloud seeding, we can force the clouds to rain in Kerala and Karnataka. Rather than reaching Delhi.
Imagine if the winds in India are blowing from west to east. Suppose clouds are passing over the desert of Rajasthan. If we use cloud seeding to bring rain in Rajasthan, the clouds will be exhausted. Had cloud seeding not been used, the clouds might have reached Delhi and would have been heavy enough to rain on Delhi.
So, in a nutshell, cloud seeding technology is merely giving us a choice. Do we want the clouds to rain in Rajasthan or in Delhi? Should it rain sooner or can we delay it? We can control only this. We do not have control over creating clouds over Rajasthan if there were none to begin with. This is not possible.
