It does not have the ability to suddenly produce all kinds of heavy rain and snow, Tessendorf said, adding, That process is just not really set up to take a cloud that may not be an effective precipitation producer and suddenly make it into the most efficient flood-producing cloud.. Wivenhoe Dam Brisbanes main source of water and also a key piece of infrastructure to stop the city flooding starts rising rapidly from 58% capacity. Like: 'we have the pilots' names, we know where you live, you're going to pay for this,' kind of stuff," Handel told AFP. Atmospheric water is one such alternative resource.

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. 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. China, which already artificially alters its weather over major cities, plans to be able to modify weather over half its territory by 2025, to the alarm of neighbours including India. Water vapor in the atmosphere can then adhere to the particles, and condense into raindrops or snowflakes. 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. Domensino says while several features in the atmosphere combined to deliver the rain, climate change likely made the event worse.

Another weapon used to flood everyone,' a third wrote. The delivery of this salt is to vaporize them by ignition by a flare device. An atmospheric research expert told The Associated Press that cloud seeding would not change the dynamics of a cloud enough to cause massive flooding. Cloud seeding can also, in some cases, cause the cloud to grow larger and last longer than it would have without the modification. Cloud seeding involves modifying a cloud's structure to increase the chance of precipitation. 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. We are no longer accepting comments on this article. The increased snowfall can also benefit ski resorts within the cloud seeding areas.
