Weather. Weather modification is the act of intentionally manipulating or altering the weather. The most common form of weather modification is cloud seeding, which increases rainfall or snowfall, usually for the purpose of increasing the local water supply. [1]
Prior to the Environmental Modification Convention signed in Geneva in 1977, the United States used weather warfare in the Vietnam War. Operation Popeye saw the use of cloud seeding over the Ho Chi Minh trail. It was hoped that the increased rainfall would reduce the rate of infiltration down the trail.
Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation, mitigate hail or disperse fog. The usual objective is to increase rain or snow, either for its own sake or to prevent precipitation from occurring in days afterward.
It opened for signature on 18 May 1977 in Geneva and entered into force on 5 October 1978. The Convention bans weather warfare, which is the use of weather modification techniques for the purposes of inducing damage or destruction. The Convention on Biological Diversity of 2010 would also ban some forms of weather modification or geoengineering.
Rainmaking is a weather modification ritual that attempts to invoke rain. Among the best known examples of weather modification rituals are North American rain dances, historically performed by many Native American tribes, particularly in the Southwestern United States. Some of these weather modification rituals are still implemented today.
Weather modification via cloud seeding has a long history in perennially dry Southern California. [1] Santa Barbara County has been cloud seeding with both ground-based machines and dedicated cloud-seeding airplanes since the 1980s. [1] In 2016, Los Angeles County rebooted its cloud seeding program (with ground-based machines) for the first ...
Climate engineering (or geoengineering) is the intentional large-scale alteration of the planetary environment to counteract anthropogenic climate change. [1][2] The term has been used as an umbrella term for both carbon dioxide removal and solar radiation modification when applied at a planetary scale. [3]: 168 However, these two processes ...
Rainmaking. Rainmaking, also known as artificial precipitation, artificial rainfall and pluviculture, is the act of attempting to artificially induce or increase precipitation, usually to stave off drought or the wider global warming. [1] According to the clouds ' different physical properties, this can be done using airplanes or rockets to sow ...
