In the UAE, they’re making it rain by zapping clouds. The idea is that the zap will charge tiny rain drops and cause them to stick together. Larger drops are more likely to fall as rain. I have no idea how it’s actually supposed to work, but all I’ve seen is news reports and those are generally worthless for technical details.
Assuming this works, and apparently it does, we could use this in the US. Zap some of those clouds over the western fires and get some rain on them.
