This episode was produced by Collective Next. 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. The aim is to get other innovative projects from scientists in the field of rain enhancement from all over the world, with the winning ideas obtaining a grant of $5 million to work and improve on concepts for a period of three years.

In Gympie, the towns central business district is inundated. A look at aerial and ground-based cloud seeding techniques. So it is a synergistic effect. On the other hand, cloud seeding practice is to release artificial seeding materials as nuclei to initiate the water vapor in the cloud to condense into droplets and promote the formation of large droplets until they grow big enough to fall as rain. A planned factory marks a major milestone in the US for new batteries that enable lower-cost, longer-lasting EVs. A conspiracy theorist claims destructive rain and flooding in south-eastern Queensland and northern NSW are the result of man-made weather manipulation from "cloud seeding".. So far, there are no reports of cloud seeding or floods in Tasmania in 2022. If experts complete seeding at the right time, it leads to more moisture supply, which will eventually create rainwater. Cloud seeding adds small, ice-like particles to clouds.

The 'ice embryos' interact with the surrounding water droplets, and eventually grow to snowflakes. As the water spreads to northern New South Wales, how did the so-called rain bomb develop? It involves manipulating existing clouds to try and help them produce more rain or snow. Welcome, Dr. Zou. Everything from wind speed, air movement and updraft, or a current of rising air, can affect a storms strength, Tessendorf said. Because the process is random and uncertain, the form and size of the particle cannot be controlled and most are probably too small to be effective cloud seeding materials. March 28, 2022.
