The discussion confirms that lightning in the tropics contributes to the creation of AC, DC, and neutral fields/currents in the Earth, primarily through the ionospheric layer's electrical conductivity. Thunderstorms function as giant Van de Graaff generators, charging the ionosphere and creating a constant electric field across the Earth's surface. The Schumann Resonance phenomenon, linked to low-frequency atmospheric electromagnetic waves produced by lightning, is also highlighted as an area of interest. Additionally, a continuous influx of charged particles, including dust and precipitation, contributes to the Earth's net positive charge, with an average worldwide current flow of approximately 1800 amps.
PREREQUISITESAtmospheric scientists, electrical engineers, environmental researchers, and anyone interested in the interactions between lightning, atmospheric electricity, and Earth's electromagnetic fields.
Tyger said:The ionospheric layer of the atmosphere is electricaly conductive and can transport charges anywhere on the planet. Thunderstorms act like giant VanDeGraff generators and charge up the ionosphere-earth as though it were an enormous Leyden jar. This produces a faily constant electric field over the whole surface of the earth.
