[..]China is using two massive drones to seed rainclouds in Sichuan province to try to end a devastating drought that has choked power output and disrupted supply chains of global giants like Apple Inc. and Tesla Inc.
The China Meteorological Administration launched drones in northern and southeastern Sichuan on Thursday morning, and the aircraft will eventually cover an area of 6,000 square kilometers in operations lasting through Monday, state-owned CCTV reported. [..]
[..]Seeding works by dropping an ice-forming agent like silver iodide into a cloud that already contains ample moisture. Rain droplets gather around the agent, gaining weight until they begin to fall. China has a long history of using the technology to water crop fields, cool blistering cities and make sure skies are clear for events like the Olympics.[..]
The googles don't have much to say. Try this query:
"china cloud seeding results"
What I got was lots of hits about how China was going to build a weather modification infrastructure - something like half dozen or more years ago.But, the hits continue with more recent ones about how they are going to do more seeding.
Still, is it safe to infer from any lack of evidence that it failed?
I don't know, but when you study those hits, you do find hits which suggest that cloud seeding doesn't work.
