Experts say no single factor can explain this extreme weather, pointing instead to warmer oceans and saturated soils as contributing factors. How do those compare to cloud seeding materials? Cloud seeding has strict requirements. The map above depicts shallow groundwater storage in Australia from November 11-14, 2022, as measured by the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) satellites. 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 small one could be 20 meters and the large one could be like a building. Multiple posts on Facebook - as seen here, here and here - attempt to link Australia's floods with cloud seeding and possible government manipulation of the weather. 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 . Siems, a professor who leads a Monash University team studying clouds and precipitation, said the practice is not conducted in the Northern Rivers region and it cannot cause flooding. Researchers have been trying to . 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. Social Credit? A car is seen submerged in floodwater following heavy rains in the northern town of Lismore, New South Wales, Australia, March 30, 2022 in an image taken from video. It involves manipulating existing clouds to try and help them produce more rain or snow. Source: Snowy Hydro. The extra water produced from cloud seeding can sit in water storages for multiple years. Hotter atmospheric conditions and oceans are driving much heavier rainfalls, scientists say. 15 February 2014. Prime inner-city areas including much of the South Bank precinct are underwater. Additionally, silver iodide, a common agent . Feast to Famine: Mass Floods and Australia's High-Speed Rail. The claim is false. At the moment, all possible solutions that could resolve the water shortage issue should be examined carefully. 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. Cloud seeding is a real thing. In the 1950s, another scientist named Bernard Vonnegut proposed his cloud seeding idea in which he noted that clouds need other particles like bacteria or algae to produce precipitation. Copyright 2023 CBS Interactive Inc. All rights reserved. Cloud seeding gives these clouds a lot more ice crystals (or cloud nuclei). Top Stories. The area of cooler air in the upper atmosphere drifts into the low pressure trough and starts to deliver record-breaking downpours over Brisbane and its surrounds.

If we had started where we started from in 2011 we would be in serious trouble.. . Conspiracy theorists claim the motive for'elites' carrying out a 'weather attack', which submerged communities around Byron Bay and Lismore, was to move people into 'smart cities'. NSW's Snowy Mountains region. The first cloud seeding trials were carried out by Kraus and Squires (1947) near Sydney. "Cloud seeding is not that effective, people do it only under very special circumstances," he said. 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. At Gympie, 200km north of Brisbane, a flood warning is issued for the Mary River. These small droplets and crystals usually form around even smaller particles of dust, salt and other aerosols floating in the atmosphere, which are called cloud condensation nuclei. 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. 2023 BBC. Cloud seeding is still practiced in the Snowy Mountains in NSW today, carried out by Snowy Hydro Limited. Get in touch. [2] [3] Around 85,000 people were displaced by the flooding or requested to leave their homes by authorities. Dr. Zou: Yes. UAE is in the arid climate zone, and the government has already taken the initiative of this UAE research program for re-enhancement science. But experts say the flooding has been worsened by climate change and a La Nia weather phenomenon. Domensino says while several features in the atmosphere combined to deliver the rain, climate change likely made the event worse. 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.". So they form super cool vapor and crystallize into ice particles. Unfortunately, such material is unpredictable, where and how much available. 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. "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.". 2022. A 2016 news clip was associated with the recent floods in Australia. Ice nucleation is important. It is important to note that the American Chamber of Commerce in South China (AmCham South Thousands of residents were ordered to leave their homes. The flight lasted an hour and 34 minutes over the Upper Derwent catchment, targeting Lake Echo. 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. 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.

Handel said he tasked his operations manager, Anthony Berko, with responding to each email and calling people who provided their phone numbers. A really strong storm, she explained, will already have a very strong updraft and windflow characteristics that help create the cloud to begin with. BBC. Cloud seeding was conducted a day before the recent floods in Australia. A flooded road is seen in Lismore, New South Wales, Australia, following heavy rains on March 2, 2022.

Cloud seeding can use either ground based generators and / or aviation for operations. Others pointed to terms used in media coverage as proof the floods were part of an 'attack' and not natural. It never developed in . It can enhance precipitation in areas experiencing drought, among other uses. 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. 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. Cloud seeding is used in parts of Australia to enhance rain, snowfall and water security. The natural occurring condensation nuclei are such as dust particles, volcano flash, or pollens. They say it's all part of a government plan to "weaponise" the weather against its own people - a popular conspiracy trope that has been around for years. Formerly, cloud seeding was rejected in Australia on environmental grounds because of concerns about the protected species, the pygmy possum.

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. Laurel: Could you describe that weather chamber that you used in your experiments? In my project, we have changed the surface of the material to make it more reactive so it can work at a lower and wider relative humidity to make it more likely to happen. Cloud seeding can also, in some cases, cause the cloud to grow larger and last longer than it would have without the modification. 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.
