Cloud seeding operations target clouds with silver iodide to influence rainfall.
Many programs utilise both ground generators and aircraft.
SEEDING FROM THE AIR
In this, the driest inhabited continent on earth, cloud seeding has been carried out in various locations over some 60 years and is seen by some as a potential panacea to the ‘effects of climate change’.
These weather modification programs have traditionally used planes to target clouds and draw out more precipitation, known as cloud seeding, in order to create more rainfall.
In the following video, reporters take a look at Weather Modification International and their traditional cloud seeding program, demonstrating the techniques used during this method:
Cloud seeding experiments began in Australia in 1947, shortly after the classic experiments of Schaefer (1946) in America showing that pellets of dry ice could rapidly glaciate a laboratory cloud.
In recent years, cloud seeding has evolved from aerial-based operations to mountain-tops on the ground.
In the following video, reporters visited one of the longest-running cloud seeding operations in the United States to get a full demonstration of Automated High-Output Ground Seeding Systems (AHOGS).
Ground-based options have become a viable alternative for the industry, citing a more ‘sustainable’ approach to weather manipulation that doesn’t involve the use of planes in the environment.
The DRI Cloud Seeding Research Program, for example, primarily uses ground-based generators.
While most look up to the skies for patterns and movements, a midst leaks down from tall mountains.
