In the future, we could snuff out cyclones. But weather control comes with new risks

It may soon be possible to reduce cyclone formation and intensity by spraying particles into the atmosphere above a forming storm. But the technology opens up a can of worms

Cloud seeding can increase rain and snow, and new techniques may make it a lot more effective – podcast

Cloud seeding – spraying materials into clouds to increase precipitation – has been around for nearly 80 years. But only recently have scientists been able to measure how effective it really is.
Sometimes air goes up past the condensation level then falls back below the condensation level, then up, then below, again and again. This creates clouds that are stripy, often with lines between the clouds. Robert Lawry/Author provided

Curious Kids: where do clouds come from and why do they have different shapes?

Clouds formed by rising warm air currents are called ‘convection clouds’. Because of all the rising air coming up, these clouds can be bumpy on top, sometimes looking like cotton wool or cauliflower.

Making rain with lasers

Shooting lasers into the air can trigger the formation of water droplets, a technique that could be used to help stimulate…
