CLAIM: A rain-enhancing process known as cloud seeding caused historic flooding in Tasmania, Australia, in 2016 and along Australias southeastern coast this year. The post's caption states, "There were no flood warnings for the area in Tasmania targeted by a cloud-seeding operation the day before floods devastated the town of Ouse." Hundreds replied to his post with comments claiming 'the government' was using experimental technology to carry out 'cloud seeding' - a weather modification process that theoretically alters the microphysical state of clouds, causing rain. A really strong storm, she explained, will already have a very strong updraft and windflow characteristics that help create the cloud to begin with. It involves manipulating existing clouds to try and help them produce more rain or snow. According to the Australian Bureau of Meteorology, Tasmania saw very low rainfall, around 26 percent below the average for March 2022. The first three months of 2022 brought a year's worth of rain to Sydney. in response calling the claims misinformation and denying that it conducts cloud seeding flights, stating that it only operates an aerial photography aircraft. All Rights Reserved. Clouds form when water vapor in the atmosphere cools and condenses to form tiny water droplets or ice crystals in the sky. 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. In a 2016 news report from the Australian TV network 7News, the broadcasters discuss Tasmanians' worries that cloud seeding might have contributed to the state's worst floods in forty years. The global water shortage has continuously intensified by rapid population growth and economic development around the world. Covered in this AustraliaOne Update -. Nobody has ever seen this amount of rain in such a short period of time over our south-east catchment, says the Queensland premier, Annastacia Palaszczuk. The first cloud seeding trials were carried out by Kraus and Squires (1947) near Sydney. Laurel: Could you describe that weather chamber that you used in your experiments? 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. Brisbane has two features that make it susceptible to flooding. Is that correct? Were not altering the updraft of the clouds. 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. In Australia, water can be a scarce commodity, with variousareas of the country suffering through prolonged droughts at times. NOTE: Dry ice used for cloud-seeding = solid carbon dioxide = CO2. 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. Of these four experiments, the Snowy Mountains saw statistically significant increases in rainfall during the experiment. While scientists have blamed the. 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. 'I have known for years they have been using this technology!' China is developing a weather-modification system that aims to divert water vapour thousands of miles through the sky and bring rainfall to the country's driest regions. Dr. Zou: It is a challenge area and I have collaborated with the Cloud Microphysics Modeling International team. This is done by firing small particles (usually silver iodide) into clouds. As floods devastated Australia's east coast, social media posts accused a pilot of causing the disaster through cloud seeding, a weather modification technique that involves dropping a rain-inducing chemical into clouds.
