the most successful work in this area so far was recently done by Saudi Arabia, or was it UAE, idk, somewhere around there... it's basically a very high powered negative ion generator mounted on a light plane

what makes clouds form is negatively charged dust particles. that's it!

this happens naturally in massive amounts when we get solar winds or coronal mass ejections hitting hard enough to get through the magnetic field, also ultraviolet light and several other forms of high energy photons also do this, they ionize oxygen, which leads to a electric potential

part of this is why the most intense type of rain always includes electrical discharges, because the clouds are fully loaded up with negative charge (electrons), and where there is sufficient positive charge and the conductivity of the space between the clouds and the ground is sufficient, you get an electrostatic discharge aka lightning

there's no way that this kind of cloud seeding could seriously alter the natural bias caused by the shielding or absorption of solar energy into the upper atmosphere but at the same time it could tip a borderrline flood situation into a full out flood

the military/intelligence agencies have made much hoo-hah about their ability to do this stuff, but it's fake... sorry, not sorry, most of what you hear about is fake, they did experiments, they didn't really work well, and they puffed it up and then sent it out as a limited hangout

the ONLY thing we can do about the weather is use more energy to do stuff like store bumper crops, to build shelters against weather, to power lighting systems to grow plants when the energy from the sun has caused massive constant cloud cover and light blocking

changing the weather is a fool's game, and at absolute worst, can possibly cause an unintentional catastrophe by tipping a delicate balance over into a state change such as enough extra rain to cause sinkholes and landslides, or triggering earthquakes that were almost going to happen, or causing an otherwise benign volcanic area to bust open and burn everything
