This temperature is much higher than most other known ice nucleate material. , first developed in the 1940s, involves spraying fine particles of silver iodide and dry ice into a cloud system. Under NSW legislation, Snowy Hydro can only cloud seed when precipitation is likely to fall as snow to elevations below 1,400 metres. The PUB should constantly monitor the weather patterns and warn the people when a flood is about to occur. Prof Bofu Yu, of Griffith Universitys Australian Rivers Institute, says in 2011 rainfall was concentrated in the west and not as widespread as the current flooding. They vary in size. 2022 AFP. 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. Do not sell or share my personal information. FILE - Buildings are surrounded by flood waters in Londonderry on the outskirts of Sydney, Australia, Thursday, March 3, 2022. Recent research suggests that the decades-old approach can be effective, though questions remain about how much water it can wring from the sky. Companies covered in Cloud Seeding Market are RHS Consulting, Ltd North American Weather Consultants, Inc. Dr. Zou: It is a challenge area and I have collaborated with the Cloud Microphysics Modeling International team. Pilots get "really violent" threats after online rumors wrongly pin devastating floods on cloud seeding. Towards New Zealand, Domensino says, an area of high pressure known as a blocking high stops the system from moving away into the Tasman Sea. As the trough is expected to move slightly east, computer models show that by Friday there is a bit of a bullseye over Brisbane, a BoM forecaster says. So it has a huge possibility to improve its efficiency. In the midst of an historic megadrought, states in the American West are embracing cloud seeding to increase snow and rainfall. The higher you move up to the atmosphere, quickly moving into subzero and very cold. To help advance the science, in 2015 the UAE government launched a new initiative, the UAE Research Program for Rain Enhancement Science. 'The Gold Coast and surrounds is currently under a government weather warfare attack,' he told his army of devoted followers. [2] [3] Around 85,000 people were displaced by the flooding or requested to leave their homes by authorities. In Australia, a La Nia increases the likelihood of rain, cyclones, and cooler daytime temperatures. Farm Heroes Saga, the #4 Game on iTunes. Dr. Zou: Yes. Wivenhoe has never dealt with that volume of water but it was lucky it was down at 60% at the start. APS ASSESSMENT: False. While scientists have blamed the. We designed and fabricated a porous nanocomposite of 3D reduced graphite oxide and silica dioxide nanoparticles. 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. Here are the tales of two unsuccessful Queensland rainmaking experiments -Brisbane, 1882 Advertisement, The Brisbane Courier, January 31, 1882In January . 2022 . To achieve this, we use the nanotechnology to deposit titanium dioxide nanoparticles as a shell layer and sodium chloride crystal core. The information and techniques are out of date and their effectiveness is not well understood. A look at aerial and ground-based cloud seeding techniques. Defence and National Security Intelligence. A La Nia develops when strong winds blow the warm surface waters of the Pacific away from South America and towards Indonesia. 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. In the open environment, it's more challenging. The language they are using such as "rain bombs" is clear enough for me,' a commenter said. Iran has already accused Israel of stealing its water by using cloud-seeding that reduces rainfall over its territory. How do those compare to cloud seeding materials? This data describing my new seeding materials property and their interactions in atmosphere. one wrote. Cloud seeding can also, in some cases, cause the cloud to grow larger and last longer than it would have without the modification. The flight lasted an hour and 34 minutes over the Upper Derwent catchment, targeting Lake Echo. 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. A high tide on Sunday evening pushes the river higher as the rising ocean water effectively holds back the freshwater. As the water spreads to northern New South Wales, how did the so-called rain bomb develop? Silver Iodide is safe to use in cloud seeding operations because it is found naturally in the atmosphere, soil and sediments of the Snowy Mountains region. As a result, flooding this time has been much more extensive from small creeks and large rivers, he says. Dr. Zou: The conventional cloud seeding materials include mostly hydroscopic salt mixture, which can change from salt crystals into water droplets at the right condition. 'If you also know this, comment on your awareness of unnatural weather below. more time. Dr. Zou: In the natural water cycle on the earth, the sun irradiates on the surface of our planet and the water on the surface is evaporated by the heat as the vapors. As Brisbane starts a long and costly clean-up, hundreds of cars are stuck on the main M1 highway to the south. It has been used in Australia intermittently since 1947. Published: 00:57 EDT, 31 March 2022 | Updated: 00:57 EDT, 31 March 2022. As well as the rising river levels, the amount of rain falling locally causes flash floods all across the city and its outer suburbs as creeks swell, inundating areas that escaped the 2011 floods. This material can initiate ice nucleation followed by rapid growth starting from a temperature of minus 80 degrees. This salt vapor then will recondense as very small particles. About as much as eight months' worth of rain has come down in just four days, bringing parts of Australia's largest city to a standstill. The information and techniques are out of date and their effectiveness is not well understood.. Trials in Tasmania were also successful and since the 1960s, Hydro Tasmania has continued cloud seeding over the state. [4] [5] The floods' damage was significant because rain fell on . Social media users are sharing a news clip from 2016 about cloud seeding the day before a severe flood in Southern Tasmania. The term 'rain bomb' was coined by Daily Mail Australia in 2017 to describe sudden and intense rainstorms, and has since been picked up by politicians and even the Bureau of Meteorology. Many of the accounts seen by the BBC posting this type of content have also shared other conspiracy theories involving global warming, Covid vaccines, and the Moon landings. 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. The costs are split among state agencies in Colorado, Utah and Wyoming, where the . According to Domensino, some 611.6mm of rain fell on the city between 9am Friday and 6pm Sunday the highest three-day total in records dating back to 1840. The BoM has said heavy rainfall events will get more intense as the world gets hotter. That hasn't stopped some TikTok users from denouncing "weather engineering". 'It is very obvious. I'm the Director of Insights, the custom publishing division of MIT Technology Review. Cloud seeding trials continued through the late 1950s and early 1960s by the CSIRO in the Snowy Mountains, in the New England district of NSW, the Warragamba catchment near Sydney and in the York Peninsula in SA. This cloud seeding area spans over the high elevation areas of the Snowy Mountains within the Snowy Hydro water catchment area, covering approximately 2110 square kilometres. Cloud is an effective and safe way to enhance rain and snowfalls above natural levels. The small one could be 20 meters and the large one could be like a building. For cloud seeding to produce rain you need moisture to begin with. Since the 1940s, scientists have studied ways to increase rainfall with the goal of increasing precipitation in arid and semi-arid climates. 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.

Once this water is released from the hydropower lakes, downstream river catchments can also benefit from increased water to irrigate crops. . Clouds form when water vapor in the atmosphere cools and condenses to form tiny water droplets or ice crystals in the sky. For general feedback and enquiries, please contact us through our Help Desk. "These aerial captures are commissioned after major weather catastrophes and natural disasters, including following the recent east coast flooding," the NearMap spokesman said. Cloud seeding aims to protect flood-hit Jakarta. Reuters quoted the Bureau of Meteorology, which said Sydney had received 1,227 mm (48 inches) of rain so far this year, more than its average annual rainfall of 1,213 mm adding that many coastal towns could see up to 180 mm (7 inches) of rainfall. 3 January 2020. Conspiracy theorists . The delivery of this salt is to vaporize them by ignition by a flare device. Cloud seeding involves modifying a cloud's structure to increase the chance of precipitation. However, both are far overshadowed by the disaster of 1804, whose water discharge, with a peak discharge of about 1,200 m3/s, was twice as massive as the 1910 event. An amusement ride is seen inundated by floodwaters in Sydney. The claim is false. As you know, cold clouds with sub-zero temperatures are also present in the atmosphere. (Audience submitted: David Bradley)"The extent to which cloud seeding has exaggerated the flood is still . Despite the online claims, cloud seeding is not responsible for any of the east coast floods, said weather modification expert Simon Siems. Cloud seeding programs in the upper Colorado River Basin, for instance, cost around $1.5 million each year. Why Is the Government Cloud Seeding in NSW's Over the Areas That Have Just Been Ravaged by Floods? THE FACTS: In recent months, Australias southeastern coast has experienced some of its, in more than a decade, leading some social media users to highlight a previous instance of flooding and spread false theories about what caused, Twitter users are sharing a clip from a 2016 news broadcast about flooding in Tasmania to claim it proves that. Share. A decades old idea, with todays innovation, might be the answer to help drought-stricken countries and to fight climate change. 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. This type of microphysical response is very unlikely to produce such an overwhelming change in the cloud.. "Cloud seeding is a . This is done by firing small particles (usually silver iodide) into clouds . Dr. Zou: The cloud seeding materials used today have been around for many decades. Flashes into the high RF appear on RADAR sometimes in the same geometric modulation patterns spoken about in HAARP research papers they appear coordinated with other stations, and not all stations in the same area produce the flash. 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 . The comments below have not been moderated. April 8, 2022 / 6:52 AM / AFP .

'Cloud seeding is being used to increase rainfall by corrupt governments to act on mother nature. Social Credit? . The 'ice embryos' interact with the surrounding water droplets, and eventually grow to snowflakes. Cloud seeding was conducted a day before the recent floods in Australia. Laurel: Although cloud seeding has been around for decades, how does today's technology move it toward a greater success rate? Its no wonder then that several 'cloud seeding' (rain-making) experiments have been conducted in Australia. "Handel Aviation operates aerial photography aircraft only. There is devastation in northern NSW as Wilsons River rises two metres above previous flood records, inundating the town of Lismore. In just four days, the equivalent of eight months' worth of rain fell, paralysing certain areas of Australia's largest city. 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. It involves manipulating existing clouds to try and help them produce more rain or snow. 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. 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. 'I've been in Wagga Wagga for the last four days and the amount of chemtrails in the sky above the Riverina region is beyond comprehension,' the person commented. Design thinking was supposed to fix the world. It is not yet known whether these findings also apply to wild conditions. Our in-depth reporting reveals whats going on now to prepare you for whats coming next. Bartolo was handcuffed on his lounge room floor in a struggle seconds after the police broke inside. 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. On social media, they blame the extreme rainfall on "cloud seeding" and "weather manipulation". Electric vehicles have been available for decades. All Rights Reserved. "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.". This shows us the risk is real to have two serious flood events in just 11 years is a pretty high frequency for a major city like Brisbane to have to deal with.. It involves manipulating existing clouds to try and help them produce more rain or snow. In Australia, cloud seeding is used in some areas to increase surface water runoff for use in the production of hydropower. James Bartolo, a prominent former Melbourne anti-lockdown activist and Covid denier, promoted the bizarre, false explanation on his Facebook page. This is done by firing small particles (usually silver iodide) into clouds . Dr. Zou: Yes, you are right. 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!. There is already local flooding from the intense and incessant rain that is interspersed with violent thunderstorms. Water vapour gathers around the particles and eventually falls as precipitation. Cloud-seeding is a weather-modification practice used to artificially create or promote additional rain/snow from existing clouds. The report did not find evidence to prove that the cloud seeding flight contributed to the flood. But conspiracy theorists aren't buying it. A subtropical climate naturally suited to big rain events and a city and suburbs built beside rivers and creeks in front of mountain ranges. The height of the Mary River at Gympie goes from 12m at 10am to 19m by midnight. It can enhance precipitation in areas experiencing drought, among other uses. 'I have known for years they have been using this technology!' 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? We know the oceans are getting warmer and that puts more moisture in the atmosphere, and a warmer atmosphere can hold more moisture.. 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. 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. Laurel: To successfully cloud seed, you need a number of things: 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. By James Dinneen March 3, 2022. The BBC is not responsible for the content of external sites. Compared to the current flood, the factor is almost threefold. 2023 BBC. In it, the newsreader reports on concerns by Tasmanian residents that the region's worst floods in 40 years could have been linked to cloud seeding. Through the advancement in nanotechnology and nanoscience, nowadays we are working to design and engineer cloud seeding materials with optimal properties to ensure water vapor condensation will occur effectively and maximize the rainfall achieved. Domensino says while several features in the atmosphere combined to deliver the rain, climate change likely made the event worse. Laurel: 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. The government can also provide flood insurance for the people. 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. "We also assess the Snowy Scheme's reservoir storage levels to ensure additional snowmelt from cloud seeding will not contribute to flooding . Some of those he contacted were surprised or angry, Berko said. It can enhance precipitation in areas experiencing drought, among other uses. The flight was collecting images for aerial maps provided to Australian mapping company NearMap, he said. 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. Dr. Zou's research interests include applying nanotechnology and membrane science to the development of low energy and high efficiency novel desalination and water purification solutions. A really strong storm, she explained, will already have a very strong updraft and windflow characteristics that help create the cloud to begin with. . 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. 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.
