This material can initiate ice nucleation followed by rapid growth starting from a temperature of minus 80 degrees. A dangerous and bizarre conspiracy theory is circulating that the devastating floods which have torn through Australia's east coast are part of a 'government weather warfare attack'. The first trials were carried out near Sydney by Kraus and Squires in 1947. Scientists blame intense rainfall on a . To be successful, scientists need the right air temperature, the right humidity, a surface that attracts water and keeps it, and then the correct size material to allow condensation to form on the particle. This is done by firing small particles (usually silver iodide) into clouds. The condensation nuclei that give birth to clouds are extremely small, measuring around two micrometres, which is about 1/100th the size of a single cloud droplet. Compared to the current flood, the factor is almost threefold.

A team of pilots is conducting an investigation by releasing the seeding materials and in real time capturing and analyzing them. The pilot's aviation company said it was conducting aerial surveys for a . We know the oceans are getting warmer and that puts more moisture in the atmosphere, and a warmer atmosphere can hold more moisture.. The silver iodide causes water droplets in the clouds to form ice crystals that become heavier and fall faster, releasing precipitation. Cloud-seeding is a weather-modification practice used to artificially create or promote additional rain/snow from existing clouds. Snowy Hydro's Cloud Seeding Program boasts that it has been able to increase rain or snow by 14 percent over the colder months. EPA. So, what is cloud seeding, how does it work and where is it used in Australia? Cloud seeding is a form of planned weather modification. Do you have a story for me? Is that correct? Everything from wind speed, air movement and updraft, or a current of rising air, can affect a storms strength, Tessendorf said. reach out to us at 7.4 Cloud seeding from a plane uses silver iodide burners, dry ice pellets or hygroscopic flares. If we had started where we started from in 2011 we would be in serious trouble.. one wrote. "Handel Aviation operates aerial photography aircraft only. Second, having the efficient seeding material for water droplet formation. One widely shared post singled out an aviation company to make the unfounded claim that it ran a cloud seeding flight that was contributing to large-scale flooding in the city of Lismore. 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. It's very promising to know more about the effects of this seeding material. At the moment, all possible solutions that could resolve the water shortage issue should be examined carefully. NearMap confirmed to AFP the photos taken by Handel Aviation were commissioned to map disaster-affected areas for insurers and emergency services. Conspiracy theorists claim the floods devastating Australia's east coast are a 'government weather warfare attack' triggered by 'chemtrails' James Bartolo, former Melbourne anti-lockdown leader . Silver iodide is an ice-forming agent, which causes supercooled water droplets to freeze in the clouds. There are scenes of devastation in low-lying suburbs, along creeks, and in the river itself where pontoons break free and ferry terminals are littered with smashed boats and debris. Mass Floods and Australia's High-Speed Rail. Laurel: Certainly, a number of possible commercial ventures. One patent is filed on the titanium dioxide, sodium chloride material for warm cloud seeding, and another patent is filed for porous graphite oxide, silica dioxide, nano compensated for cold cloud seeding. Conspiracy theorists spread the false claims after weeks of torrential rains led to deadly east coast floods over the past two months, engulfing homes and sweeping cars from the roads. Australia, March 30, 2022 in an image taken from video. He was charged with incitement for allegedly encouraging his social media followers to attend an illegal rally. Handel Aviation operator Mark Handel told AFP on Thursday that the company does not seed clouds. Play it now! 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. This temperature is much higher than most other known ice nucleate material. At 10pm, Seqwater starts to release some of the water building up in Wivenhoe Dam. Cloud seeding is used in parts of Australia to enhance rain, snowfall and water security. My research work has been supported in their first cycle and received excellent worldwide exposure. There was a high degree of luck in terms of where we started from [with Wivenhoe Dam], he says, adding that the climate crisis will only raise the risk of future events. Singapore should also build more drainage canals to effectively reduce the occurrence of . (AP Photo/Rick Rycroft), Connect with the definitive source for global and local news. Cloud seeding can use either ground based generators and / or aviation for operations. The government can also provide flood insurance for the people. Could this all just be a . An amusement ride is seen inundated by floodwaters in Sydney. Mr Bartolo's followers claimed aircraft leaving 'chemtrails' in the sky across NSW is how the cloud seeding process is being administered. Seeding clouds as a way to change weather began its history as a serious science during WWII, originally as a way to interrupt severe storms or to produce rain and snow. Cloud seeding was first trialled in Australia in 1947 when the CSIRO got up in a light plane and released crushed dry ice into promising-looking clouds. The 2022 eastern Australia floods were one of the nation's worst recorded flood disasters with a series of floods that occurred from February to April in South East Queensland, the Wide Bay-Burnett and parts of coastal New South Wales. 'Moving people into so-called 'smart cities' is likely, I think, considering the World Economic Forum openly talks about these things. Unlock more weather data and layers options. Thanks for listening. For the third time this year, Sydney has been hit by major floods. Conspiracy theorists claim the motive for 'elites' carrying out a 'weather attack', which have seen communities around Byron Bay and Lismore underwater is to move people into 'smart cities'. Is that correct? What are the challenges with then deploying the material out in the real world? As you know, cold clouds with sub-zero temperatures are also present in the atmosphere. Read about our approach to external linking. Why Is the Government Cloud Seeding in NSW's Over the Areas That Have Just Been Ravaged by Floods? However, there is no evidence that cloud seeding was responsible for the flood. Why are you interested in this type of research? Australia One Party (A1) - Update March 3, 2022. Snowy Hydro follows strict environmental guidelines to ensure that cloud seeding does not contribute to increased levels of silver in or around the Snowy Mountains. Today, that endeavor is making incredible leaps and bounds as scientists and engineers apply nanotechnology to improve the effectiveness of cloud seeding. THE FACTS: There's no evidence to suggest that cloud seeding played a role in either flood, and an atmospheric research expert told the AP that cloud seeding would . Posts shared online alleged aerial survey pilots from Handel Aviation caused a second deluge in the flood-ravaged New South Wales town of Lismore on March 31 by cloud seeding dispersing a substance into the clouds to prompt rain. Hydro Tasmania (HT)s cloud seeding activities on 5 June had no impact on precipitation, with this conclusion having a solid scientific basis, stated the June 2017 independent parliamentary, Hydro Tasmania also denied that its flights were to blame and said in a, shows the operation had no measurable impact on rainfall on that day., Sarah Tessendorf, a project scientist at the Colorado-based. Hydro Tasmania also denied that its flights were to blame and said in a statement that an analysis shows the operation had no measurable impact on rainfall on that day.. Handel Aviation posted a statement in response calling the claims misinformation and denying that it conducts cloud seeding flights, stating that it only operates an aerial photography aircraft. Cloud seeding is perhaps the ultimate silver bullet, in which literal silver in the form of silver iodide is infused into clouds, causing ice crystals to form and water to condense into rain or snow. Usually, silver iodide particles are used. The analysis, which was also supported by the governments independent review, found that based on data collected by the aircrafts instruments and data from the Bureau of Meteorology, the cloud being seeded was already precipitating and contained significant amounts of ice, so efforts to initiate additional precipitation had no effect. But a probe by the Tasmanian government into the 2016 flooding has since been completed, and investigators and expert atmospheric scientists found that cloud seeding by Hydro Tasmania, a government-owned generator of renewable energy, did not contribute to or worsen the heavy rains. Pictured: Large parts of Lismore in NSW are completely underwater after record rainfall, Hundreds replied to the post with messages claiming 'the government' is using experimental technology to carry out 'cloud seeding'. In Australia, a La Nia increases the likelihood of rain, cyclones, and cooler daytime temperatures. Laurel: Then in the real world where we don't have this controlled chamber, it's not quite as easy necessarily to measure that kind of success. This is done by firing small particles (usually silver iodide) into clouds . Some areas that flow into the river have had 300mm of rain in just six hours. But experts say the flooding has been worsened by climate change and a La Nia weather phenomenon. Some conspiracy theorists have been sharing a 2016 news report from the Australian TV network 7News - which has now been watched thousands of times. Nearmap, which analyzes and distributes the companys photos, confirmed in a statement to the AP that the claims associating Handels recent flight with cloud seeding are false.

We only operate aircraft fitted with cameras for aerial photography survey purposes and we are not sure where this misinformation has started, Handel Aviation posted on its website, adding, our recent flights over flooded areas of NSW and QLD are in response to the floods. The increased snowfall can also benefit ski resorts within the cloud seeding areas. Nanotechnology can engineer material and design the material with well controlled size, shapes, and properties. Cloud seeding got its start in 1947, with General Electric scientists working under a military contract to find a way to de-ice planes in cold weather and create fog to obscure troop movements. Laurel: Your research focuses on the cloud seeding material itself, specifically the nanomaterials as you mentioned, which is a more effective tool in generating rain from existing clouds. So it has a huge possibility to improve its efficiency. Oct 15 (Reuters) - Floods caused by torrential rain are hitting large swathes of southeast Australia, inundating hundreds of homes and forcing authorities to urge thousands of people to evacuate . It's obvious when viewed on the radar.'. To achieve this, we use the nanotechnology to deposit titanium dioxide nanoparticles as a shell layer and sodium chloride crystal core. These fall to the ground as snow or raindrops, depending on the surface temperatures. who leads the centers work on cloud seeding, told the AP that claims linking the process to flooding lack an understanding of how cloud seeding works.
