Blame it all on:
https://geopolitics.co/2015/06/06/us-air-force-admits-they-can-control-weather/The US Air Force and DARPA would like us to believe that they have stopped using HAARP in Alaska for research and experiment. Even then, we all know that there are other HAARP systems out there in the form of radar communication and surveillance systems that are rigged on top of mobile platforms that are deployable in any international waters around the world.
All they need to do is twist a button to change the frequency to microwave range and increase the frequency modulated [FM] transmission power enough to reach and heat up the atmosphere above the target.
The technology is covered under US Patent 4,686,605 on the “Method and Apparatus for Altering a Region in the Earth’s Atmosphere, Ionosphere, and/or Magnetosphere.”
An increase of 1 Celsius in the atmosphere is more than enough to initiate a significant weather perturbation. Bear in mind that all gases move from high to low pressure, and gas pressure is directly proportional to its temperature.
In short, if one heats up at least three points in the atmosphere, the center region having relatively lower pressure than those three heated points will become the eye of the storm. Three competing forces moving towards a common region can only be resolved through a downward spiral rotation, the cooler gases being heavier than the former. Depending on the amount of energy being used, the whole process could take days.
