I am familiar with the concept of cloud seeding, where precipitation can be induced with aerosols, thereby altering storm intensity further downwind. Are there methods that could be used to drastically alter storm wind intensity or storm direction? What technology could theoretically be developed in the future that used satellites, ocean networks, balloons, or other devices to curb strong winds (e.g. tornadoes or hurricanes) so that populated areas could be protected. Or is a strong storm simply too large scale of an event to be altered significantly by humans?
IRI's (Ionospheric Research Instrument or HF Radio Transmitter) can be used to excite specific areas of the ionosphere. The resulting heat creates a high pressure system that can be then be used to push the jet stream or prevent it from moving. This is the type of equipment that world powers had in mind when they signed the Kyoto Protocol 50 years ago (banning weather warfare). Its also what the USAF had in mind when they wrote the manual "Weather as a Force Multiplier. Owning the Weather by 2025".
According to the USAF and the Defense Advanced Research Projects Agencies (DARPA) very own website, HAARP is designed to excite the ionosphere. This results in a super heated mass that expands outward, and therefore creating a high pressure system.
High pressure systems whether natural or man made have a direct impact on the path that a weather system will take. The jet stream will take the least path of resistance for example. When it encounters a high pressure system it is forced to take a different path. A high pressure system acts like the bumpers on a pin ball machine. This isn't a theory, it is meteorological science.
Whether or not the system is used for good or evil is another, unrelated topic.
I provided several references to credible sources that explain this technology in my previous answer. I will add to the list as you requested and hope that the additional references and citations adequately address your concerns.
USAF manual “Weather as a force Multiplier. Owning the Weather by 2025” can be found here:
United States Patent # 4,686,605 can be viewed on the US Patent offices website and offers a full description of the capabilities of the system:
The USAF’s official website that describes the installation has apparently been removed in anticipation of the planned disassembly of the installation. But archives of the website can still be found here:
Wikipedia's article on the topic can be found here:
And here's another article on Wikipedia that should illustrate the seriousness of weather warfare technologies and the precautions that various countries have taken to prevent abuse of the technology.
