The technique known as weather modification is utilized in various countries to manipulate atmospheric processes to influence local weather conditions. A key method in meteorological modification involves the introduction of substances such as Silver Iodide, Sodium Chloride, and Carbon Dioxide into clouds to act as condensation nuclei, facilitating the formation of raindrops. This process heavily relies on factors like wind patterns and atmospheric temperature.
The process of cloud seeding is intricate, starting with specialists identifying suitable clouds, conducting thorough assessments, and then loading a drone with the necessary substances. Upon dispersal over the cloud, the cloud's size increases, leading to water accumulation and eventual rainfall.
The objectives of cloud seeding can vary depending on prevailing weather conditions. The technique was pioneered by Vincent Joseph Schaefer in the United States, marking the beginning of meteorological experimentation and weather manipulation for agricultural purposes.
Despite undergoing numerous research studies, cloud seeding has shown potential benefits in specific scenarios, with its effectiveness being contingent on particular weather conditions. However, concerns regarding environmental and ethical implications arise due to potential changes in rainfall patterns, water quality, and the risk of global conflicts over water resources.
In certain countries, cloud seeding presents challenges to established protocols and guidelines aimed at mitigating adverse environmental impacts.
While cloud seeding is practised in various countries, its long-term effectiveness remains a subject of ongoing evaluation and discussion.
