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. Social media users are also sharing a separate example to baselessly claim that cloud seeding played a role in. 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. Cloud-seeding is a weather-modification practice used to artificially create or promote additional rain/snow from existing clouds. In Australia, water can be a scarce commodity, with variousareas of the country suffering through prolonged droughts at times. Water vapor in the atmosphere can then adhere to the particles, and condense into raindrops or snowflakes. 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. Formerly, cloud seeding was rejected in Australia on environmental grounds because of concerns about the protected species, the pygmy possum. Singapore should also build more drainage canals to effectively reduce the occurrence of . They vary in size. 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. As the water spreads to northern New South Wales, how did the so-called rain bomb develop? That's it for this episode of Business Lab. "Cloud seeding is not that effective, people do it only under very special circumstances," he said. To achieve this, we use the nanotechnology to deposit titanium dioxide nanoparticles as a shell layer and sodium chloride crystal core. Water that seeps deep into the soil can influence groundwater levels for months. Between 1967 and 1972, during the Vietnam War, it spent roughly $3 million each year on weather modification . 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..
