In a short story I am writing I have a magic system that involves nanotech left behind from an ancient advanced civilisation that can allow for magic like effects. In this story the characters primarily use this nanotechnology to control the weather by creating several weather phenomena like tornadoes, thunderstorms, blizzards, and hurricanes. However, I do not know if nanotechnology would ever have the capacity to impact the weather in the ways I have described.
This nanotech has spread across the entirety of earths atmosphere. Given the fact that I got a degree in creative writing and not in physics or technology I lack the knowledge of weather and nanotechnology so I apologise for any mistakes that I have made in my question. Also, this ancient civilisation had a tech level that is around a century ahead of the current world civilisations technology so inter dimensional technology that can cross universes would not exist at the time. So would nanotechnology be able to control the weather in any significant ways? Thank you guys in advance.
