Cloud Seeding

Cloud seeding is a weather modification technique used to either create or increase precipitation by dumping certain types of materials into the sky. T

he purpose of a material used is to facilitate the coalescence of cloud droplets into larger droplets, which will fall as precipitation, such as rain. Some commonly used agents for cloud seeding are silver iodide, potassium iodide, or sodium chloride; all of which can serve as nuclei to allow moisture to condense.

Cloud seeding can be accomplished with respect to clouds having sufficient moisture using aircraft, rockets or ground-based devices that disperse the particles into the atmosphere.

Cloud seeding is particularly beneficial for places experiencing drought, water supply limitations, or unreliable precipitation patterns. It provides a way to improve water availability for uses such as agriculture, drinking, and electric power generation from hydropower.

Cloud seeding has been used to alleviate damaging impacts from hailstorms and to disperse fog at airports to improve visibility and safety. Cloud seeding has been undertaken by countries and India as a potential solution to water management concerns and agricultural productivity.

With its potential benefits come controversy in some sectors. Critics assert that altering natural weather patterns can result in destructive environmental conditions and the distribution of rain and snow. Others criticize the chemicals used to seed clouds and their effects over time as research continues.
