Hight Altitude Auroral Research Program were a series of patents issued to Roland Esuand for Arco Research while developing a gas field in Northern Alaska. There was no feasible way to transport the gas, so they designed a phase array antenna to be powered locally by the gas for ionospheric heating. Auroral research was just an ancillary mode, by heating the ionosphere with billions of watts of energy and heating the gas to plasma, all sorts of effects can be achieved from over-the-horizon radar to earth penetrating tomography. So much energy can be dumped into the earths core that liquefaction of magma can occur giving rise to earthquakes, similarly by heating the right air mass one can divert the jet stream and cause downstream weather effects on mass scale. Hurricanes, droughts, monsoons, the sky is the limit when you have electroenergetic control over the skies.
