A homogenitus, anthropogenic or artificial cloud is a cloud induced by human activity. Although most clouds covering the sky have a purely natural origin, since the beginning of the Industrial Revolution , the use of fossil fuels and water vapor and other gases emitted by nuclear, thermal and geothermal power plants yield significant ...

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.

2019年2月26日 · Unlike a brightened cloud at sea, which may last for three days, an artificial stratospheric layer would likely linger – like the Mount Pinatubo eruption – for up to two years.

NASA’s cloud creation is not a sinister plot but rather a scientific experiment aimed at advancing our understanding of Earth’s upper atmosphere. These artificial clouds are produced by...

2024年4月17日 · What is cloud seeding and did it play a role? Cloud seeding involves manipulating existing clouds to help produce more rain. This can be done by using aircraft to drop small particles (like...

2016年5月26日 · But in this new study, a group of scientists shows that Earth can actually produce these particles without any help from humans. Instead, it gets made from a mix of tree vapours and highly energetic particles that bombard …

2025年1月16日 · Contrails are cloud-like formations made up of tiny water droplets or ice crystals. They form when the hot exhaust gases from an aircraft’s engine, which contains water vapor, meet the cooler, low-pressure air at high altitudes.

Like natural clouds, artificial clouds can drastically affect the weather: In the daytime they block the sun, creating shade and reflecting some solar radiation back into space. But at night, clouds have a blanketing effect that keeps warm air trapped.

2023年12月21日 · Artificial cloud formation, also known as cloud seeding or cloud modification, is the intentional introduction of substances into the atmosphere to stimulate the formation or modification of clouds.

US1338343A is a U.S. patent for a process and apparatus designed to create artificial clouds, fog, or mist using heat, pressure, and chemicals. US1338343A : Artificial Clouds, Fog, and Mist Production is one of the most revolutionary patents in the …
