WEATHER MODIFICATION TECHNOLOGY(WMT) Artificial rain also known as cloud seeding is a form of weather modification that involves injecting substance into cloud to enhance precipitation. This article explores the science behind cloud seeding , its various methods, the several processes involved, as well as its effectiveness and environmental impact. Cloud seeding creates artificial rain by injecting substances such as silver iodide, potassium iodide, dry ice (solid carbon dioxide), liquid propane, or salt into clouds in order to induce precipitation. By dispersing these substances the microphysical processes within the cloud are altered and precipitation is improved. Clouds are composed of tiny water droplets or ice crystals that form when water vapor in our atmosphere cools and condenses around a particle of dust or salt floating in the air. Cloud seeding stimulates this process by introducing particles that act as ice nuclei, allowing ice crystals to form, which w...
