MHD is a more extensive application of plasma physics. My point was to indicate that I have an education in the subject. The ionosphere is all plasma.

I don't know where you get your information about power level, but HAARP's own website only claims 3.6 MW of transmit power. A megawatt is slightly more than a thousand horsepower. This is absolute peanuts compared to any weather phenomena, and there is no way that events in the ionosphere affect events in the troposphere.

No, HAARP was NOT designed to "bounce off the ionosphere." The power beam is absorbed by the ionosphere as heating...which is dissipated within minutes by the ionosphere's natural turbulence. By the way, antennas are designed for one wavelength, or a narrow wavelength band. Why is that? Because the antenna has to be a certain harmonic ratio with the wavelength for efficient transmission. I would say "this is basic physics here," but you have beat me to that punch line. And, yes, they would build a dedicated multi-million-dollar facility with a transmitter designed specifically to excite the ionosphere, if they were doing phenomenological research on the ionosphere. Why would you want to "change wavelengths" when that would confer no benefit to your research program?

What you have done here is to manufacture a fantasy of your own imagination and superimpose that on a facility whose purpose and technology you don't understand.
