August 19, 2025 - Hygroscopic seeding adds particles to the cloud with the intent to modify the number and size of liquid drops while glaciogenic seeding targets the number and size of ice crystals. Although cloud seeding technologies for purposes like augmenting precipitation, reducing hail damage, and dispersing fog are still developing, recent research in wintertime glaciogenic orographic cloud seeding has shown significant progress, demonstrating an evidence-based causal relationship for this specific method.

January 24, 2026 - The chemtrail conspiracy theory supposes that jet contrails are chemically altered to modify the weather and other phenomena. Other theories attempt to implicate scientific infrastructure such as the High-frequency Active Auroral Research Program (HAARP). In the franchise of both The Bionic Woman and The Six Million Dollar Man. In 1976, the weather control machine by Dr. Franklin, played by John Houseman featured in the "Kill Oscar" trilogy. Frank Herbert's Dune series features weather control technology, mainly on two planets: Arrakis, where the technology is used by the Fremen to assure privacy from observation and hide their true population and their plans to terraform the planet from the Imperium; and, Chapterhouse, where the Bene Gesserit intend to turn the planet into a desert.

September 29, 2024 - Although weather modification schemes have caused significant impacts to communities such as inducing droughts or causing flooding, they usually don’t intend to alter the climate more broadly and, for that reason, they aren’t considered to be geoengineering. However, there is significant overlap between many geoengineering and weather modification methods, and weather modification technologies are also important precursors particularly to Solar Radiation Modification (SRM) schemes.

August 23, 1998 - In Russia, various other former Soviet republics, and South Africa, the major programs of weather modification were aimed at reducing the fall of damaging hail. Experimentation in this area was apparently successful. Procedures involved introducing ice nuclei into potential hail clouds by means of artillery or rockets.

Weather modification refers to the intentional alteration of weather conditions through techniques such as cloud seeding, which involves injecting particles into clouds to enhance precipitation.

Weather modification (also known as cloud seeding) is an environmentally friendly way to generate more precipitation from clouds in the form of rain or snow. It works through the introduction of tiny particles (“seeds”) that create additional ...

This technology assessment looks at how policies might address challenges such as: ... Cloud seeding is a decades-old approach to modifying weather that uses a range of supporting technologies for research and operations. According to NOAA, the most common uses of cloud seeding are to increase precipitation or suppress hail, usually by adding tiny particles of silver iodide.

Planned weather modification programs benefit from a comprehensive understanding of the physical processes responsible for desired modification effects. Recent improvements in the composition and techniques for dispersion of seeding agents, observational technology, numerical cloud models, ...

February 27, 2026 - Submission Information & Frequently Asked Questions What is "weather modification"? Any activity performed with the intention of producing artificial changes in the composition, behavior, or dynamics of the atmosphere.

Cloud seeding is a weather modification technique aimed at enhancing precipitation from clouds Cloud precipitation efficiency, defined as the ratio of the amount of rain reaching the ground to the amount of water vapor entering the cloud base, is often clearly below unity.

Weather modification, commonly known as cloud seeding, is the application of scientific technology that can enhance a cloud's ability to produce precipitation. Weather Modification, Inc., is on the forefront of scientific technology to maximize water availability worldwide.

April 12, 2017 - Development of autonomous UAS equipped with sensors to improve weather modification operations and research. ... Instrumented UAS target and implement seeding for improved safety and cost effectiveness. ... Similarly equipped UAS fly in tandem for improved targeting. ... UAS facilitate Eulerian and Lagrangian analyses of seeded cloud systems. ... Improved UAS technology and automation may lower the cloud seeding operational footprint.

This includes: Cooling the earth ... the SWMS services include: Weather modifications (cooling, warming, altering precipitations, altering air mass velocity components), supply of energy (direct solar power, indirect wind or ...

We saw, numerous times this summer, and just this past weekend, in Indiana and Kentucky, that weather has a profound impact on the lives of Americans. And this afternoon, the Subcommittees will be discussing weather modification, and, specifically, legislation introduced by my colleague, Senator Hutchison, Senate bill 517, the Weather Modification Research and Technology Transfer Authorization Act.

November 4, 2025 - Rain Enhancement, also known as cloud seeding, offers a sustainable source of fresh water by enhancing rainfall from specific clouds under specific conditions. This technology can boost the rainfall of a specific cloud by up to 25% under optimal ...

September 10, 2024 - WM refers to various techniques, such as cloud seeding, that attempt to enhance or suppress precipitation, for example to combat droughts. WM aims to change local or regional weather and precipitation, but not overall climate patterns.

Weather Modification, Incorporated is the leader in atmospheric assessment and evaluation. Since 1961, we have been working in the sky, providing unmatched, scientifically based meteorological services and atmospheric solutions.

May 6, 2019 - Cloud seeding is a weather modification technique that improves a cloud’s ability to produce rain or snow by introducing tiny ice nuclei into certain types of subfreezing clouds. These nuclei provide a base for snowflakes to form.
