if they can do this in Dubai..
why can’t LA do this during fire season?

Cloud seeding doesn't create moisture. It pulls together existing moisture in the air until it is heavy enough to precipitate and fall out of the sky as rain.

Humidity in LA during the peak of the fires was 5-15%; which is part of the reason the fires were so devasting, most vegetation is heavily desiccated by humidity that low, especially combined with high temperatures, and so highly flammable. 

Humidity in Dubai is routinely between 55-65%.

I think to increase localised humidity you’d need some kind of water atomiser or evaporation system. But the scale would have to be enormous to have any meaningful impact and you’d need access to a lot of water and a lot of energy.

I don’t think it’s something that could be done at short notice or without pre-existing fixed infrastructure. Might be something that wealthy coastal cities in fire prone areas deploy as a climate adaption measure in the distant future.

The strong winds which accompanied these fires (and which simultaneously fanned the flames and further desiccated vegetation) would also increase the difficulty of artificially creating local humidity because they’d rapidly whip away any atmospheric moisture introduced artificially.

But @aviationdoctor.eth is probably more qualified to speak on the topic than me.

Thank you for the insight. I didn’t think about the humidity precondition, but that makes some sense.. so then LA would really just need technology to increase the humidity quickly into similar percentages in collaboration with the other cloud seeding tech
