Note that this experimental outlook is based upon emerging and controversial research which strives to exploit a yet to be ascertained part of the Earth-Solar interface. As these outlooks are purely experimental they should not be used for planning purposes. Electricity has been studied for the last several decades, but it has been in the past 20 years that the weather connection has become clearer.
Basic physics explains how the two interact.
A dialectric is a material that acts as an insulator between two electrically charged bodies. The stronger the dialectric, the stronger the electric change can be. In the atmosphere, water acts as a dialectric between the earths surface and the upper, strongly charged ionosphere. Radiation from the sun is carried to the earth by the solar wind. As solar radiation strikes and interacts with the top of the earths ionosphere, strong electric currents are developed.
