In Australia, cloud seeding is used in some areas to increase surface water runoff for use in the production of hydropower. . Water that seeps deep into the soil can influence groundwater levels for months. The BBC is not responsible for the content of external sites. Scientists blame intense rainfall on a combination of factors - but, on social media, unfounded allegations of "weather manipulation" have spread widely. Nanotechnology can engineer material and design the material with well controlled size, shapes, and properties. Handel Aviation operator Mark Handel told AFP on Thursday that the company does not seed clouds. Play it now! Electric vehicles have been available for decades. Smart Cities World Forum. What kind of effect can cloud seeding potentially have on a country, like the UAE, which typically only records four inches of rain in a year? Water vapor in the atmosphere can then adhere to the particles, and condense into raindrops or snowflakes. Dr. Zou: It is a challenge area and I have collaborated with the Cloud Microphysics Modeling International team. Hotter atmospheric conditions and oceans are driving much heavier rainfalls, scientists say. I used an eight cubic meter chamber with controlled humidity and temperature. 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. Social media users are sharing a news clip from 2016 about cloud seeding the day before a severe flood in Southern Tasmania. 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.
