A subtropical climate naturally suited to big rain events and a city and suburbs built beside rivers and creeks in front of mountain ranges. "Cloud seeding is not that effective, people do it only under very special circumstances," he said. Given climate change is a background to all weather events, its hard to say that it does not play a role, he says. Cloud seeding was conducted a day before the recent floods in Australia. So, what is cloud seeding, how does it work and where is it used in Australia? 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, explains Dr. Zou. To help advance the science, in 2015 the UAE government launched a new initiative, the UAE Research Program for Rain Enhancement Science.

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. If experts complete seeding at the right time, it leads to more moisture supply, which will eventually create rainwater. Vivek Ramaswamy: The Indian . 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. 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 . According to Snowy Hydro, their Cloud Seeding Program increases precipitation by an average of 14 percent. Cloud seeding is a real thing. Cloud seeding has strict requirements. In Australia, a La Nia increases the likelihood of rain, cyclones, and cooler daytime temperatures. Ben Domensino, a meteorologist at Weatherzone, says the low pressure trough is delivering the rainfall but an area of colder air higher in the atmosphere is drifting in, making the atmosphere unstable and allowing moisture to be lifted up and dropped as rain.
