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. According to the clouds' different physical properties, this can be done using airplanes or rockets to sow to the clouds with catalysts such as dry ice, silver iodide and salt powder, to make clouds rain or increase precipitation, to remove or mitigate farmland drought, to increase reservoir irrigation water or water supply capacity, to increase water levels for hydropower generation, or even to solve the global warming problem.
In the United States, rainmaking was attempted by traveling showmen. It was practiced on the American frontier, but may have reached a peak during the dust bowl drought of the US west and midwest in the 1930s. The practice was depicted in the 1956 film The Rainmaker. Attempts to bring rain directly have waned with development of the science of meteorology, laws against fraud, and improved weather forecasting, with some exceptions such as cloud seeding and forms of prayer including rain dances, which are still practiced today. Prayers for rain is also a common cultural practice for Christians and Muslims.
The term is also used metaphorically to describe the process of bringing new clients into a professional practice, such as law, architecture, consulting, advertising, or investment banking—in general, processes that bring money into a company.
It is also used to describe a confidence trick where the scammer takes money from the victim to influence a system over which they have no real control, but a random chance of the outcome happening anyway.
Since the 1940s, cloud seeding has been used to change the structure of clouds by dispersing substances into the air, potentially increasing or altering rainfall. In spite of experiments dating back to at least the start of the 20th century, however, there is much controversy surrounding the efficacy of cloud seeding, and evidence that cloud seeding leads to increased precipitation on the ground is highly equivocal. One difficulty is knowing how much precipitation might have fallen had any particular cloud not been seeded. Operation Popeye was a US military rainmaking operation to increase rains over Vietnam during the Vietnam War in order to slow Vietnamese military truck activity in the region though this claim happened 60 years later by anti-government groups. Rainmaking is not climate engineering, which seeks to alter the climate, but a form of weather modification, as it seeks only to change local weather.#Science #ScienceNews #Rain #Clouds #Rainmaking #cloud_seeding 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.
