Intro: As some of you may know, the character shown in this picture is none other than the Weather Wizard, one of the Flash's most dangerous adversaries. With the help of rod-like device in his hand (or his "weather wand" as he calls it), he can do just about anything with the weather, such as summon lightning bolts from the sky, create powerful tornadoes or even hurricanes, and even be precise enough to change the air pressure and the temperatures in specific areas of his choosing, just to name a few of his abilities he uses to keep the Scarlet Speedster on his fast-moving toes.
Explanation: Obviously, the idea of manipulating and controlling the weather in real life is nothing new. In fact, there are many conspiracies theories that the US government has had control of a weather machine since the 70's to create monsoons in Vietnam to help their armed forces in the war (look up "HAARP weather machine"). Some people even believe part of our current problem with climate change is due to man-made weather manipulation.
Suggestions: Regardless, what I'm trying to figure out is how one of these things could actually work because many sources on these weather machines aren't really specific on the science behind it. And even if we could deduce the science behind one of these machines, is it possible we could turn it into a portable device like the Weather Wizard has here? Many sources I've looked up on this say that this kind of machine would use intense microwave radiation through lasers from below to heat up the atmosphere in a similar fashion to what the sun does to our atmosphere from above, such as in this video here: https://www.youtube.com/watch?v=hm1_TfTgUag. The Earth's electromagnetic field is also said to be responsible in affecting the weather (like this document here: https://ieeexplore.ieee.org/document/7112935), so is there maybe a way a device like this could affect electromagnetic fields? Either way, this would probably require a significant amount of energy, so I'm not even sure it could fit into a device the size and the shape of a metal rod.
Question: So yeah, how could, in theory, a real-life "weather wand" that can summon tornadoes, rain, and lightning bolts, and manipulate air and wind currents and temperature (just to name a few) all at the drop of a hat?
Please feel free to call me out on any scientific inaccuracies I have stated or other aspects of science related to this that I have either overlooked or seem less knowledgeable about. Thanks.
