1,000 balloons Scientists from 10 countries are conducting an experiment to demystify the life cycle of tropical clouds. Under the experiment, 1,000 weather balloons have been released over the past two months in Australia's northern city of Darwin to study cirrus, the wispy white clouds found at high altitudes.

"Cirrus are ubiquitous in the tropics and have a large impact on the environment, but the properties of these clouds are poorly understood,' the organisers said in a statement. These clouds carry heat and moisture from the Earth's surface high up in the atmosphere
