Because the coated nanolayers are more hydrophilic and porous, the water can be absorbed easily and increase the local relative humidity of the crystals and increase the probability of forming water droplets. We will revisit our evidence and verdict and conduct additional research to verify new information. Reuters quoted the Bureau of Meteorology, which said Sydney had received 1,227 mm (48 inches) of rain so far this year, more than its average annual rainfall of 1,213 mm adding that many coastal towns could see up to 180 mm (7 inches) of rainfall. I used an eight cubic meter chamber with controlled humidity and temperature. Cloud seeding is perhaps the ultimate silver bullet, in which literal silver in the form of silver iodide is infused into clouds, causing ice crystals to form and water to condense into rain or snow. 'I have known for years they have been using this technology!' Cloud seeding involves adding small particles into existing clouds to help them grow. Clouds form when water vapor in the atmosphere cools and condenses to form tiny water droplets or ice crystals in the sky. The area of cooler air in the upper atmosphere drifts into the low pressure trough and starts to deliver record-breaking downpours over Brisbane and its surrounds.
