Yes, such type of applications. Today, that endeavor is making . Since silver iodide and not elemental silver is the cloud seeding material, the claims of negative environmental impact are disputed by peer-reviewed research as summarized . China, which already artificially alters its weather over major cities, plans to be able to modify weather over half its territory by 2025, to the alarm of neighbours including India. Twitter users are sharing a clip from a 2016 news broadcast about flooding in Tasmania to claim it proves that cloud seeding provoked the heavy rainfall. A spokesman for the state's water authority says the dam doesn't have a flood mitigation component, so no water was released ahead of the downpour, which came when the state's dam network . Iran has already accused Israel of stealing its water by using cloud-seeding that reduces rainfall over its territory. In the open environment, it's more challenging. Thanks for listening. An independent investigation sought by Tasmania's parliament into the causes of the 2016 flooding found that cloud seeding, a process aimed at increasing precipitation, had no impact on the severe weather. Singapore should also build more drainage canals to effectively reduce the occurrence of . "Cloud seeding is not that effective, people do it only under very special circumstances," he said. Cloud seeding experiments began in Australia during 1947 after American scientists made the discovery in 1946. How do those compare to cloud seeding materials? Two words for you: nanoengineered materials. A Facebook post with over 23K views asserts this claim with footage from a news broadcast about cloud seeding before a severe flood in Southern Tasmania. Dr. Zou: As we know, the global water shortage has continuously intensified by rapid population growth and economic development around the world. Trains are cancelled, bus services limited, the main Bruce Highway is closed at multiple locations and 51,000 people are without power.

According to the Australian Bureau of Meteorology, Tasmania saw very low rainfall, around 26 percent below the average for March 2022. The most common particulate used in cloud seeding is silver iodide, which has a similar structure to ice crystals and helps supercooled liquid water droplets cluster together. Experts say no single factor can explain this extreme weather, pointing instead to warmer oceans and saturated soils as contributing factors. Steven Siems, from Monash University's School of Earth Atmosphere and Environment, is a cloud expert. They are made of many super cooled water vapors, so although they are below zero, they remain as vapor. Once such cloud encounters the ice nucleation particles, they rapidly form a large number of ice crystals and bypass the liquid water phase. Cloud seeding aims to protect flood-hit Jakarta. Additionally, silver iodide, a common agent . At the moment, I'm working collaboratively on a project to evaluate the effects of these materials in the open air. Some of the natural sources include bushfires, volcanoes and dust storms, while artificial sources of condensation nuclei include industry emissions and cloud seeding operations. It will initiate from the thin water layer formed on the surface of the ice nuclease, and the ice will grow rapidly at the expense of the water vapor in the cloud. In the 2016 clip from the Australian TV network 7News, a journalist says, Residents in southern Tasmania are demanding to know why cloud seeding was conducted over the Derwent River catchment the day before the worst floods in 40 years., One social media user shared the old clip Tuesday with the caption, Remember when this was a CONSPIRACY NOW - CLOUD SEEDING IS NOW OPENLY REPORTED - MAKING FLOODING WORSE - investigations are now being conducted as to WHY this was done!. Theres no evidence to suggest it played a role in the 2022 floods in southeastern Australia, either. Recent social media posts claim that the 2022 floods in Australia were caused or exacerbated due to cloud seeding. Cloud seeding is a real thing. Queensland Premier Annastacia Palaszczuk has expressed her concern over the impact of the floods as the state is inundated by rain. Laurel: Your research signifies a milestone toward achieving greater water security in the world. 2022 AFP. NearMap confirmed to AFP the photos taken by Handel Aviation were commissioned to map disaster-affected areas for insurers and emergency services. The claim is false. We know the oceans are getting warmer and that puts more moisture in the atmosphere, and a warmer atmosphere can hold more moisture.. A Hydro Tasmania spokesperson told the AP that it has since stopped conducting cloud seeding. Conventional water resources such as rivers, lakes, and groundwater have become very limited, which is driving scientists and engineers to look for alternative water resources. In partnership withUAE Pavilion Expo 2020 Dubai. We call them UAEREP [United Arab Emirates Research Program for Rain Enhancement Science]. Snowy Hydro also has other criteria for cloud seeding which includes; In addition to these atmospheric conditions, Snowy Hydro also takes into account the amount of water already in the landscape. The unsubstantiated claims have been spreading at a concerning rate on social media, with thousands seemingly convinced the record rain in northern NSW and Queensland are a 'man made' phenomenon. in response calling the claims misinformation and denying that it conducts cloud seeding flights, stating that it only operates an aerial photography aircraft. NOTE: Dry ice used for cloud-seeding = solid carbon dioxide = CO2. In the U.S., studies have found a few percentage points of increase in precipitation. This is a black-and-white photograph of a cloud-seeding operation over the Pacific Ocean near Sydney. Cloud seeding has strict requirements. Today, that endeavor is making incredible leaps and bounds as scientists and engineers apply nanotechnology to improve the effectiveness of cloud seeding. Laurel: In the past, one of the challenges scientists encountered when researching cloud seeding was the lack of a simulation environment. Image: How cloud seeding works in the NSW Snowy Mountains. So they form super cool vapor and crystallize into ice particles. TOTT News March 8, 2022. Laurel: You were one of the first scientists in the world to explore the use of nanotechnology in cloud seeding. Cloud seeding is still practiced in the Snowy Mountains in NSW today, carried out by Snowy Hydro Limited. Australian Broadcasting Corporation (ABC News) quoted the Department of Premier and Cabinet's report on the flood in 2018. We also assess the Snowy Schemes reservoir storage levels to ensure additional snowmelt from cloud seeding will not contribute to flooding downstream, Snowy Hydro said. Cloud seeding is used in parts of Australia to enhance rain, snowfall and water security. "We don't have a co-ordinated effort to change the weather, because it's just physically and financially unfeasible," says Dr Gilbert, who adds that even if cloud seeding played a role, it would have "an absolutely minuscule effect.". Could you explain in more detail how cloud seeding works? Scientists blame intense rainfall on a combination of factors - but, on social media, unfounded allegations of "weather manipulation" have spread widely. The language they are using such as "rain bombs" is clear enough for me,' a commenter said. . Dr. Zou: It is a challenge area and I have collaborated with the Cloud Microphysics Modeling International team. The delivery of this salt is to vaporize them by ignition by a flare device. UAE Research Program for Rain Enhancement Science, New UAE cloud seeding test in Texas shows 'promising results', Roomba testers feel misled after intimate images ended up on Facebook, How Rust went from a side project to the worlds most-loved programming language. New video piece available now! Cloud seeding involves adding small particles into existing clouds to help them grow. My research work has been supported in their first cycle and received excellent worldwide exposure. The innovation of my project is the characteristics data we obtained from the experiment. This is done by firing small particles (usually silver iodide) into clouds . The first trials were carried out near Sydney by Kraus and Squires in 1947. An independent investigation sought by Tasmanias parliament into the causes of the 2016 flooding found that cloud seeding, a process aimed at increasing precipitation, had no impact on the severe weather. Dr. Zou: We want to move the materials, as I mentioned, from laboratory already and scale up, so it has a chance of reaching the market and to reach many different parts of the world as well, because there are so many countries worldwide that practice weather modification. Why Is the Government Cloud Seeding in NSW's Over the Areas That Have Just Been Ravaged by Floods? The flight path of the Handel Aviation aircraft VH-JIL criss-crossing over flooded areas was also shared online by Australian fashion designer Alice McCall alongside claims it was dropping chemicals to "activate rain.". The silver iodide causes water droplets in the clouds to form ice crystals that become heavier and fall faster, releasing precipitation. This data describing my new seeding materials property and their interactions in atmosphere. Conventional water resources such as rivers, lakes, and groundwater have become very limited, which is driving scientists and engineers to look for alternative water resources, says Dr. Linda Zou, a professor of civil and environmental engineering at Khalifa University of Science and Technology. 1. A six-year study that Wyoming conducted from 2008 to 2013 among the most ambitious done thus far estimated that cloud seeding can boost precipitation within seedable clouds by about 3.3 . EPA. But there is no evidence to suggest cloud seeding has anything to do with the current rainfall in Sydney. Australia's path towards Agenda 2030. Cloud seeding adds small, ice-like particles to clouds. He was charged with incitement for allegedly encouraging his social media followers to attend an illegal rally. It involves manipulating existing clouds to try and help them produce more rain or snow. That hasn't stopped some TikTok users from denouncing "weather engineering". Some areas that flow into the river have had 300mm of rain in just six hours. Archives of Handel Aviations website dating back to 2008 show that cloud seeding services have never been mentioned or offered on its site and there is no evidence that the company has been involved with the process. What kind of effect can cloud seeding potentially have on a country, like the UAE, which typically only records four inches of rain in a year? one follower wrote. Personalise your weather experience and unlock powerful new features. Cloud seeding. It's obvious when viewed on the radar.'. Dr. Zou: Yeah.
