Cloud seeding is a form of weather modification that mimics what naturally occurs in clouds but enhances the process by adding particles that can stimulate and accelerate the condensation process. If we had started where we started from in 2011 we would be in serious trouble.. Laurel: You've also developed another kind of technology, ice nucleating particles. The pilot's aviation company said it was conducting aerial surveys for a . Ben Domensino, a meteorologist at Weatherzone, says the low pressure trough is delivering the rainfall but an area of colder air higher in the atmosphere is drifting in, making the atmosphere unstable and allowing moisture to be lifted up and dropped as rain. Cloud seeding is usually carried out by sprinkling particles from a plane. When doing so, please reference. Laurel: That was Dr. Linda Zou, a professor of civil and environmental engineering at Khalifa University of Science and Technology, who I spoke with from Cambridge, Massachusetts, the home of MIT and MIT Technology Review, overlooking the Charles River.

They've basically lost everything and then someone has then said here's your answer," Berko said. We are no longer accepting comments on this article. Because the coated nanolayers are more hydrophilic and porous, the water can be absorbed easily and increase the local relative humidity of the crystals and increase the probability of forming water droplets. Read about our approach to external linking. Laurel: You were one of the first scientists in the world to explore the use of nanotechnology in cloud seeding. This episode was produced by Collective Next. For more information about us and the show, please check out our website at technologyreview.com. Hydro Tasmania, a hydroelectric corporation, published their analysis after the flood to say that a cloud seeding flight was undertaken on June 5, 2016, which had no measurable impact on rainfall. Cloud seeding is a real thing. It involves manipulating existing clouds to try and help them produce more rain or snow. Social Credit? EPA. Laurel: Back to your technology, you filed a patent on the cloud seeding material itself. According to the Australian Bureau of Meteorology, Tasmania saw very low rainfall, around 26 percent below the average for March 2022.

Adkins said the crew involved in the seeding reported some effect . So they form super cool vapor and crystallize into ice particles. What did you develop and how will it facilitate future research? Although cloud seeding has been around since the 1940s, climate change and population growth are driving scientists to take a closer look at the technology, which could offer a viable cost-effective supplement to existing water supplies, particularly in arid and semi-arid regions, like the United Arab Emirates. Australia One Party (A1) - Update March 3, 2022. The flooding in October 2022 is the latest in a series of major floods to affect eastern Australia since unusually wet conditions began in early 2021. This process is known as glaciogenic cloud seeding. However, experts told AFP the floods were naturally occurring and cloud seeding cannot cause flooding. out 'cloud seeding' - a weather . 15 February 2014. However, there is no evidence that cloud seeding was responsible for the flood. Dr. Zou: Yes. Ouse in the Derwent River catchment was one of the hardest hit areas in this week's floods. 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. Atmospheric water is one such alternative resource. In Australia, cloud seeding is used in some areas to increase surface water runoff for use in the production of hydropower. We are looking forward to moving the seeding materials from laboratory to the commercial venture for not only cloud seeding applications, but wider applications, such as different weather modification efforts, including agriculture or crop protection, hail, or storm suppression, and the artificial snow making at the ski resort. Since the 1940s, scientists have studied ways to increase rainfall with the goal of increasing precipitation in arid and semi-arid climates. If experts complete seeding at the right time, it leads to more moisture supply, which will eventually create rainwater. The colors depict the wetness percentile; that is, how the levels of groundwater compare to long-term records (1948-2012). Conspiracy theorists have claimed that cloud seeding leads to climate change and natural disasters like floods. To "seed" cloud formation, a small aircraft releases a cloud of particulate matter. A high tide on Sunday evening pushes the river higher as the rising ocean water effectively holds back the freshwater. What are the challenges with then deploying the material out in the real world?
