This stored water can help ensure renewable energy generation and downstream water availability during future drier years, when inflows are lower. Experts say no single factor can explain this extreme weather, pointing instead to warmer oceans and saturated soils as contributing factors. Laurel: Back to your technology, you filed a patent on the cloud seeding material itself. out 'cloud seeding' - a weather . On the other hand, cloud seeding practice is to release artificial seeding materials as nuclei to initiate the water vapor in the cloud to condense into droplets and promote the formation of large droplets until they grow big enough to fall as rain. Prof Stuart Khan, an expert on water management at the University of New South Wales, says Wivenhoe gained about 1,450 billion litres of water, which all came in under three days.

The report did not find evidence to prove that the cloud seeding flight contributed to the flood. 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. 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. one follower wrote. 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.

Four police officers knocked down the former bodybuilder's door when he refused to open it, claiming they didn't have authorisation to be on the property. Conversely, she said cloud seeding would not dramatically worsen clouds that are already forecast to produce severe weather. So we can use them as input to develop one-dimensional and three-dimensional modeling of precipitation enhancement caused by cloud seeding, and the results prove quite successful. "These aerial captures are commissioned after major weather catastrophes and natural disasters, including following the recent east coast flooding," the NearMap spokesman said. 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.. 'Surprisingly, they have talked about cloud seeding and weather manipulation on the mainstream media so it's coming from multiple sources now.

Sarah Tessendorf, a project scientist at the Colorado-based National Center for Atmospheric Research 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. A few decades later, the US military brought cloud-seeding to the battlefield. 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. These particles act as additional condensation nuclei. As the rain falls, the Brisbane River hits moderate flood levels.

Mr Bartolo's followers claimed aircraft leaving 'chemtrails' in the sky across NSW is how the cloud seeding process is being administered. 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. 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 comments below have not been moderated.

Were not altering the updraft of the clouds. One reason for the wetness is likely La Nia, which for the first time this century has returned for three consecutive years. At Gympie, 200km north of Brisbane, a flood warning is issued for the Mary River. 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. This salt vapor then will recondense as very small particles.
