I think it could be true, here is the evidence:
I live in Iran. Based on news, after missile war, most of U.S. radars in middle east is damaged.
It was suprising that after those radars goes off, we had much more rain here in comparison to last weather year. maybe 4-5 times more rain versus same season in last year!
...
I don't think radio waves of any frequency can affect clouds, or we would see them jumping around independent of wind. But there is a technological way any country can deny another's rain - cloud seeding. Make fall
before it was ready to in your territory.
Condensation leading to precipitation requires a nucleating particle (e.g., a microscopic particle of dust.) With an overabundance of nucleating particles, so many droplets form that none of them gain enough mass to fall. Some years ago when I was studying this stuff 'they' basically claimed 'accidental' geo-engineering by use of commercial aircraft. The hydrocarbon and sulfur jet engine exhaust was providing nucleating particles.
Yes, very expensive radars placed in the gulf monarchy bitch nations have been rendered junk complements of Iran's military technology, but another change can be seen by looking at what is happening vis-a-vis commercial aircraft over Iran. Check it out on flightradar24.com; it has been near zero for a while now.
It strikes me that knowing commercial aircraft schedules with precision, a slight tweak to fuel additives during fueling half way around the world on a per-aircraft basis could have profound change on what ends up in the sky over a geographic area. There would be no need for precision.
I would hypothesize that the function of the radars would be primarily to gather various kinds of data for mission planning. I also doubt that the radars could produce enough power put much energy into the atmosphere, although by use of beam-forming (a-la your modern home wifi) it might be possible on very focused points in space.
I have with my own eyes seen 'orbs' in an area suspected of geo-engineering and coinciding with a drought in California. The drought ended up resulting in legislative changes and resource 'takings' by the state. One time I saw one flash directly inside a newly laid down 'contrail' in an otherwise clear sky, and it lingered for a few seconds. I suspect that it was some form of state excitation, probably in order to take readings, but whatever technology put pin-point energy into a location should also be able to initiate chemical reactions I would suppose.
