Thank you! Food Ingredients Does cloud seeding really work? Almost extinct in the US, powdered laundry detergents thrive elsewhere in the world. In this simulation, water molecules red and white form a pentagonal lattice when they stick to a copper surface. Weather modification firms launch silver iodide flares from planes or from the ground into cloud formations to try to increase rainfall or mitigate hailstorms.

When one considers the percent of rain evaporated before rain it reaches the ground, evaporated by the soil, plants and after reaching the ground, it will be difficult to conclusively prove the cloud seeding benefits, let alone all the legal issues and claims of damages that may have taken place irrespective of cloud seeding.
The density of a cloud water aerosol in the cloud air is one in a million at best. That aerosol is in a dynamic states of evaporating and condensing all the time.
How much additional nuclei does silver iodide add to that already present in the atmosphere? Is the atmosphere really short of nuclei? The mechanism of cloud formation from forest volatile is not clear. But not every cloud can be seeded, and the process is as much art as science.
On a cold day on the ski slopes, when a cloud is hovering on the mountain, you can see evidence of this in the ice that forms on objects. All sounds good to me, anything we can do to increase our chances of powder days.
What do you reckon? How cloud seeding works. Credit: sanjindumisic. Aircraft seeding clouds. Credit: foodevolution Cloud seeding is most commonly done out of airplanes. With three-quarters of the US west gripped by a seemingly ceaseless drought, several states are increasingly embracing a drastic intervention — the modification of the weather to spur more rainfall.
We are probably looking at increased fire dangers, water restrictions and also impacts to ecosystems, such as small rivers and streams and the wildlife living there. Cloud seeding involves using aircraft or drones to add small particles of silver iodide, which have a structure similar to ice, to clouds. Water droplets cluster around the particles, modifying the structure of the clouds and increasing the chance of precipitation. Cloud seeding experiments have taken place since the s but until recently there was little certainty the method had any positive impact.
